如何鑑定田黃 How to evaluate Yellowstone

細:質地細密幼嫩,田黃質極嫩。
結:結構緊密均勻石質軟松,較堅實。
    溫:有老舊感,古董感,沉著而不輕浮,有很強的親和力。
潤:不干澀,飽滿晶瑩潤澤,如具“水色”的玉。
凝:光芒內斂,在光的照射下,其反射出的光不像珠寶鑽石那樣直接,而是好像再透過一層“水晶蠟”折射出來一樣,有一種內向收斂的感覺。
                   田黃素有石帝之稱,其上品價早已超過金價10倍。但由於開門的實物稀少,故收藏者中存在不少有關田黃的一些誤解。
            誤解1:田黃均是黃色
            田黃指福建壽山高山系田坑石中的黃色者。田坑石中不但有黃色,且有白、紅、綠、黑等多種顏色,田黃石帶紅、黑等色者也稱田紅、田黑。
            誤解2:有蘿蔔絲紋的必為田黃
            所謂蘿蔔絲紋,是指石中類似蘿蔔削皮後表面網狀分佈的纖維結構。但實際上田黃中的“蘿蔔絲紋”有多種形態:不但有類似蘿蔔的網狀紋,也有瓜瓤般的瓜瓤紋或如同粽粒融化的融粽紋,亦有通透的水流紋等。有“蘿蔔絲紋”的並不一定就是田黃,不少壽山山坑石亦有蘿蔔絲紋。雖然大多數田黃均有“蘿蔔絲紋”,但有些田黃上品沒有清晰的蘿蔔絲紋(比如故宮博物館的田黃乾隆三聯章)。
            傳統田黃相法是審美鑑賞角度的相法:從蹼狀石皮(黑、黃、白)、格(石裂)、蘿蔔絲紋入手。現代相法又加入了科學:田黃的礦物成分是地開石,非壽山石中常見的葉蠟石。據此,比較全面的鑑別法是結合傳統相法和科學分析,既要有皮格紋,亦要是地開石。有皮格蘿蔔絲則為田黃的候選,但尚待科學分析證實。另外,成分是地開石的並不一定是田黃(如昌化黃石等)。
            誤解3:凡田黃必貴重,大的必比小的好
            田黃中有上、中、下品之分。下品田黃並無大的商業價值,價比上品差幾十倍。大小方面,傳統說法一兩以上成材,二兩以上罕見。一般說來大的當然比小的好,但不是絕對的。一顆石質差、色差大、紋亂的大田黃比不上石質通靈的小田黃。一顆上品田黃必須具有石之六德:細(不粗鬆)、潔(光滑如孩兒面)、潤(油潤不枯燥)、膩(膩如肉凍,黏糕)、溫(寶氣內蘊)、凝(凝靈)。其中以靈氣和溫潤寶氣最重要。
            誤解4:田黃中的格必為血絲紅紋
            血絲紅格在黃金黃田黃中常見,但田黃的格紋還有白色、灰色等其他顏色。作偽者千篇一律將格紋做成紅色,便是基於這種不全面的誤解

出產田黃的一平方公里左右,分為→

田黃的比重2.6克/cm3,摩爾硬度為2~2.9度。


Fine: fine texture tender, very tender Tianhuang quality. Results: compact structure uniformly soft stone pine, more solid.

    
Temperature: There are old sense of antique feeling calm and not frivolous, has a strong affinity. Run: not dry, moist and full of crystal, such as a "water color" jade. Ning: Ray restrained, in the light irradiation, the reflection of the light is not as direct diamond jewelry, but seems to be through a layer of "Crystal wax" reflecting the same, there is a feeling within the convergence.


                   
Tianhuang known as Emperor Shi said its top grade gold price had more than 10 times.
However, due to the scarcity of open objects, so a lot of misunderstandings about the existence of collectors in Tianhuang.
            
Myth 1: tianhuang are yellow
            
Tianhuang refers Fujian Shoushan stone mountains line the yellow field pits were.
Field, not only with yellow stone pit, and a variety of colors white, red, green, black, etc., Yellowstone with red, black and other colors were red, also known as Tian Tian black.
            
Myth 2: There are a must for the Tianhuang Luobosiwen
            
The so-called Luobosiwen refers stone surface mesh after a similar distribution peeled carrot fiber structure. But in fact Tianhuang the "Luobosiwen" There are a variety of forms: not only have similar radish mesh pattern, there are flesh-like flesh as grain or grain rice dumplings dumplings melt melting pattern, patterns, etc. are also transparent water . There are "Luobosiwen" does not necessarily Tianhuang, there are a lot of Shoushan stone Shankeng Luobosiwen.
While most Tianhuang are "Luobosiwen", but some top grade Tianhuang no clear Luobosiwen (such as field 黄乾隆 triple chapter of the Palace Museum).
            
Tianhuang phase method is the traditional aesthetic appreciation angle phase method: From the webbed stone skin (black, yellow, white), Georgia (Stone crack), Luobosiwen start. Modernity has joined the scientific method: mineral composition Tianhuang is dickite, non Shoushan Stone common pyrophyllite. Accordingly, a more comprehensive identification method is a combination of traditional and scientific analysis phase method, which requires both Pigg pattern, also if the dickite. There Pigg radish was Tianhuang candidate, but scientific analysis confirmed yet.
Further, the component is not necessarily dickite is Tianhuang (eg CFF Yellowstone).
            
Myth 3: All fields 黄必贵 heavy, large will better smaller than
            
There Tianhuang upper, middle and low-grade points. Low-grade Tianhuang no big commercial value, lower than the top grade difference a few times. Size, say twelve or more traditional lumber, twenty-two more rare. Generally large course than small, but not absolute. A stone aberration, chromatic aberration big, chaotic pattern psychic field of small yellow stone compare Tianhuang. Tianhuang must have a top grade stone six German: fine (not coarse pine), clean (smooth as a baby face), Run (oily not boring), tired (tired as aspic, sticky rice cake), temperature (Po gas intrinsic), condensate (condensate spirit).
Among Reiki and moist air most important treasure.
            
Myth 4: The grid will be for Tianhuang bloodshot red lines
            
Yellow Yellow 金黄田 bloodshot red cells in common, but there Tianhuang other colors Plaid white, gray and so on.
Check who made the fake red monotony, is not fully based on this misunderstanding

 
Tianhuang produced about one square kilometer, divided → 1 Sakagami Tianhuang, quality spirits pale. 2 Sakamoto Tianhuang, tender quality color concentration. 3 Sakashita Tianhuang, quality condensate tired to make more tung oil colors. Sakamoto Tianhuang under 4 pestle, quality coarse color murky. 1982 Mr. Shi Chao [Indian stone debate] in tianhuang Six German → A fine, fine texture such as baby's skin. 2 knot, endoplasmic fat dense glossy, hand a slippery feel. 3 warm, intimate with the people treasure the gas, no anger. 4 Run in the palm of the hand can generate dew-like moisture, such as dew dripping. 5 condensate, condensate spirits such as translucent jelly-like. 6 greasy, muscles in the oil spill, a little dish play, such as the desire of the oil droplets.

    
Other ores, no such feeling greasy. Mr. Shi Chao [Indian stone debate] in the form of six lines of radish → 1 carrot peeled back like inner texture, mesh long eye by dense and sparse. After two glutinous rice dumplings like steamed rice is not like technology of shape.

 
Sometimes into stripes. 3 mesh over the circle, but also intermittently dispersed distribution. 4 such as melon heart pattern, overtly or covertly  distribution rules. 5 water corrugated. 6 radishes pattern is basically gone, only a few reticular pattern, is the most

 
Those goods. Proportion Tianhuang 2.6 g / cm3, mole hardness of 2 to 2.9 degrees.

“一两田黄三两金”清代的这种说法到了今天已经过时,因为现在一两田黄(寿山田黄)远远不止“三两金”——上乘田黄每克动辄达五六万,甚至更高。田黄近10年来的身份狂飙,让另外一种有着悠久文化底蕴的“疯狂的石头”——和田玉都望尘莫及。
用“‘物以稀为贵”来解释当今田黄“天价”的原因最为合适。田黄在寿山石品种中属于稀缺的珍贵品种,加上近几年来政府先后出台的种种政策,岁寿山石及田黄的资源进行保护,使得市面上的田黄越来越稀缺。另外,近年来中国艺术品市场的火爆,也让寿山石市场活跃起来,而作为珍贵品种的田黄的价格自然也水涨船高了。目前,就一级市场的成交量来看,田黄仅次于白玉和翡翠,但由于总存量远远小于前两者,所以市场热度要高的多,换手率也频繁得多,价格一路走高。
2000年到2005年,田黄的价格平稳增长。从2006年起,随着中国经济的快速发展,田黄的价格都在攀升。现如今,好的寿山田黄每克已达到20000元,这相对于前几年每克2000~5000元的价格已是翻了几番;一块完整的寿山田黄雕件,如果质优色纯,又出自名家之手,基本每克达到了50000元,甚至更高的价位。尽管如此,田黄的价格仍有上升的空间,因为好石难求。
田黄石的价格已无法以黄金而计,数年前,朵云轩在日本东京分店之石章价目表,其中有一方不定形无皮田黄,印面为1.4×0.9、高为6.2厘米,重量约27克左右,定价为2720000日元,此为不定形印,若是方印,则不可估量。 1999年6月福州市举办的“精品拍卖会”上一块500克左右的不定形田黄起叫价2100万元人民币,合国际黄金价的600倍。这个喊价,创下了国内田黄价格史上的最高记录。至于此价是否合理或能否成交,并不重要也不在这里探讨,重要的是更加说明了“今则田黄久绝,黄金有价,田黄可以无价矣。”

田黄石鉴定方法市场行情怎么样 Yellowstone market value evaluation

田黄石鉴定方法市场行情怎么样
寿山石品种繁多,色彩斑斓,不同的石种从外形、色泽至肌理,都有其独特之处。虽然上佳珍品和粗劣下品之间有天壤之别,外行的人凭着肉眼也能断其优劣,但是,假如把一百多个寿山石品种全部集中陈列在一起,要求一一道出其品名,别说一般的寿山石爱好者,就是行家里手,恐怕也得眼花缭乱,三思而慎言。尽管目前市面上常见的寿山石只有二三十种,但是,色泽相近、品质相似、肌理相似者,也不乏有之。再加上造假技术也渗透到寿山石市场之中,这就使寿山石的鉴别显得更加复杂,从而也增加了鉴别的难度。
怎么鉴定田黄石和寿山石的区别?
培养和提高寿山石的鉴别能力,主要有如下几个渠道。
第一要勤于学习、第二要严谨治学、第三要见多识广、第四要交流切磋、第五要追求精品
二种常见的鉴别法

A、经验识别法 在长期的实践中,寿山石行家们积累了丰富的鉴别经验。虽然不同的鉴别行家,总结的经验和鉴别方法不尽完全相同,但归结起来,其切入点不外乎以下几种:一是外形,包括形状、棱角、皮相;二是色彩;三是质感;四是肌理,包括纹路、裂格。
田黄石的识别

如何鉴别"石中之王"田黄石,这是寿山石收藏家和鉴赏家十分关注的问题,也是他们必备的一种鉴别能力。古今寿山石鉴赏家和研究者鉴别田黄石的经验可归纳为形状、石皮、色相、肌理、格裂形态、手感和比重。

(1)形状 根据田黄石的地质形成和演变历史,一般的田黄石都保持其天然的形状,即鹅卵形状,但在上板坑头附近出产的田黄石,有时也有棱角,这是因为这里接近溪流的源头,田黄石缺少滚动、磨练的机会。此外,还有少部分田黄石,在埋藏地下的过程中,因地壳运动,石身裂碎,分成几瓣,形成棱角,虽然经过泥土的长期滋养,但断面的棱角并未被磨平,因此有时石农在挖掘发现这种断裂性田黄石时,通常还会继续在附近寻找它的"另一半"。

(2)石皮 除了少数田黄石外表无石皮外,一般情况下,田黄石外表都有皮层包裹,因此有无石皮是鉴定田黄石的一个重要依据。

田黄石的皮层,或极稀薄、或稍厚密,石皮颜色主要有黑、黄、白、绿,皮层有单层、双层和三层,皮质比其它掘性寿山石的石皮质地要细结柔嫩,用刀轻刮,刀感流畅而微沉,粉粒细腻均匀。

Yellowstone identification method how to market Shoushan stone variety, colorful, different kinds of stone from the shape, color and texture to have their own uniqueness. Although there between a good and poor treasures beneath contempt worlds apart, lay naked people with their advantages and disadvantages can be broken, however, if the more than one hundred varieties of Shoushan stone all the focus on display together, requiring one tells its name , not to mention the general Shoushan stone enthusiasts, is the expert in, I am afraid they have dazzled, think twice and cautious. Although the common market only two or three dozens of Shoushan stone, but similar color, similar to the quality, texture similar to those, there are some with them. Coupled with fraud technology to penetrate into the market Shoushan Stone, which makes identification of Shoushan stone is even more complicated, thus increasing the difficulty of identification. How to identify the difference between Yellowstone and Shoushan stone? Shoushan stone cultivate and improve the ability to identify, there are several channels. The first to be eager to learn, and the second to rigorous scholarship, and the third to be informed, to exchange ideas fourth, fifth to the pursuit of quality Two kinds of common identification method
A, long-term experience in the identification law practice, Shoushan stone connoisseurs identification accumulated rich experience. Although different identification expert, lessons learned and identification methods are not the same, but it boils down to nothing more than following their entry points: First, shape, including shapes, angular, skin deep; two is the color; Third texture; Fourth, texture, including grain, cracked grid. Yellowstone identification
How to identify the "Stone of the King" Yellowstone, this is an issue Shoushan stone collectors and connoisseurs of great concern, but also a prerequisite for the ability to identify them. Shoushan stone connoisseurs and researcher of ancient and modern identification Yellowstone experience can be summarized as shapes, stone skin, hue, texture, grid crack morphology, texture and proportion.
(1) is shaped according to Yellowstone's geology and evolutionary history, the general Yellowstone maintain their natural shape, that goose egg shape, but in the vicinity of the plate pit head produced in Yellowstone, sometimes angular, because here close to streams source, the lack of rolling Yellowstone opportunity to hone. In addition, there are a small part of Yellowstone, buried underground in the process, due to crustal movement, crushed stone body split, divided stray form edges, although after a long nourish the soil, but the section has not been polished edges, it is sometimes Stone found that farmers in the mining fracture of Yellowstone, usually in the vicinity will continue to find its "other half."
(2) except for a few stone skin Yellowstone no stone appearance of skin, under normal circumstances, have the appearance of skin wrapped in Yellowstone, therefore identify whether the stone skin is an important basis for Yellowstone.
Yellowstone's cortex, or very thin or thicker dense, stone skin colors are black, yellow, white, green, cortex have single, double and triple, to fine leather knot than other excavation of Shoushan stone to stone cortex soft, scuffing knife, the knife feel smooth and slightly heavy, delicate powder evenly.

对于田黄石或称为“上坂”、“中坂”、“下坂”的,过去人们一直不能甚解,尤其是外地人,在概念上总是空泛的,为此,笔者曾于72年、87年、98年三次到寿山田黄产地进行了考察。

田黄石

    产地与现状
    对于田黄石或称为“上坂”、“中坂”、“下坂”的,过去人们一直不能甚解,尤其是外地人,在概念上总是空泛的,为此,笔者曾于72年、87年、98年三次到寿山田黄产地进行了考察。98年在那次考察,在友人的带领下,可谓详尽。在寿山村南面的内外洋隔界的高山山麓中,一股小清流从溪口流出,此溪当地人称为坑头溪。从溪口流出大约五、六百米间和从高山西侧流下的大段溪汇合,汇合后的溪流就是寿山溪。沿溪而下,弯弯曲曲,从寿山村内外洋绕过,又与发源旗山的大洋溪交汇。交汇处,溪中有一巨石,溪面突然狭窄,水流湍急,人们原先在此处设置水车碓米,故称“碓下”。经廻龙、双溪、带下及结门潭后缓缓流入连江县境 内。人们将产田石的沿溪水田分为上、中、下三个地段,俗称以“坂”。对于这个“坂”字,外地人多不解其意,或认为有什么奥妙,其实是地段和地点的意思。将 田黄产区分为上坂、中坂、下坂,这也是当地人的习惯称谓。文人们根据“地名从当地”的习惯原则,著之于书,公之于世,遂成为田黄产地的正式称谓。前人将坑 头溪与大段溪交汇的大段以上的水田,称为上坂,大段到大洋溪交汇处这一段的水田称为中坂,此后至碓下的水田称为下坂,从碓下到结门潭称碓下坂。近年来寿山 石农根据近二十年来所产田黄质地和生意需要又习惯地将中坂、下坂合称中坂,碓下坂称下坂。各坂所产田石分别称之为上板田、中板田和下板田。
    就 产田石而言,据记载,在这“从坑头发源地到下游的结门潭,总长大约七、八公里。数百年来,就在这溪旁或宽或窄、总面积不到一平方公里的水田中曾产过不少珍 贵的田黄宝石”。但是,也就是在这样小的产地里,经过人们数百年的挖掘,在民国时期就有“久不产石”的传闻。我国改革开放后,寿山村民为“寻宝”又掀起了 二十年的扫尾挖掘,在这二十年的挖掘中,可以说是把所有能挖到的田土又重翻了数遍。有时是全村男女老幼齐出动,不分昼夜的挖掘。目前的状况是:除中坂地段 的二亩四分地,由当地政府用石砌起加以保护禁止再挖外,其它田中就连小指头大小的“田黄仔”也遍挖殆尽。当地石农仍在不停地挖掘,他们将地段扩展到上坂的 山边,偶尔能挖到质差的小块田石。
    以地段区分
    三坂田中所产的田石略有区别,但是这种区别,不是本质上的区别,只是色泽与质地显现上的区别,就是同种田石根据质地及色泽微妙的变化可大致分出何坂段所产。
    上坂田、产于上坂,以色泽略浅者为多。林文举先生云:“上坂田质偏嫩,细腻而晶透”、方宗奎先生亦云:“色淡而质灵,酷似坑头水晶冻”。也产色浓黯褐而质如鹿目类的杂田,同时也产白田和带黑皮的乌雅皮田等。
    中坂田、产于中坂地段的水田中,大多色、质俱佳,曾多产色浓而质嫩的标准田黄。也产白田及乌鸦皮田。
    下坂田、产下坂地段,以往给人的印象是质地凝腻,色泽黝黯,多产桐油地田或黑田,但后来也曾产过不少质地灵透的上好田黄冻,该地所产田石常含细黑点。
    —碓下坂田、产碓下坂地段,质地虽灵而多硬黝,乾裂偶带青皮;黄而红褐,外层色浓至里而趋淡、萝卜纹明显、细密而稍直。多有虱卵状的小白点。另外还有一种无皮、无萝卜纹、质地嫩,裂格少质地通灵度稍逊,色泽与下坂田相同,也含有虱卵状小白点者。
    溪管田、在中板溪管屋附近的溪底出土的田石,当地石农称之为“溪中冻”或“溪管田石”或“溪坂独石”,透明度极佳。专家们认为是经山洪冲荡而落入溪底的田石,田石久蕴水中,受其浸蚀,外表泛淡黄或暗赭,石质倍加莹澈。在整个寿山溪底偶能发现。
    搁溜田、即流石当地人称“猴流田”、“滑溜田”。(搁溜为方言滚动之意),田石经田父耕作翻地,山洪雨水的冲刷转移 而露出地面的田石,往往一部份经阳光曝晒而退化,变的粗涩干裂,纹多偏直、偏粗。色泛绿灰,皮黄而少,肌里伴有黑砂钉与小白点。在上三坂及溪田表层及碓下 到回龙、双溪、带下的沙土表层可见,在这些田石中也可见到如染酱油式的田石,或无纹或有如丝状纹,特别细密。
    九手田、产于碓下坂至善伯山脚一带的寿山溪深层砂土中。掘采艰难产量稀少,相传采掘时溪底的土石须倒九道手方能运到 地面,或曰,五人为股,一人因采石断手一只,共剩九手,故称之。该田肌理或无纹或纹细如丝,皮多稀薄,色有褐红色,也有淡黄色而泛白者。质地通灵,偶见零 星小白点与黑钉。
    硬田、各坂所产肌质坚硬而粗劣的田黄,皮泛微绿,质如鹿目皮,甚至如牛旦皮,肌理或无纹,或纹路粗杂,通灵度差且含 硕砂。质地略好的类于杂田。而杂田差的也类“硬田”。无一定标准,然而以硬田制作印章者,仍不失庄重品格,当优于其它山石,兹因属田石家族,无山石火气的 “皇家”风度所致。
    以色泽区分
    田 黄石的色泽普遍泛黄色,无论是白田、红田、黑田、绿田、银裹金、乌鸦皮等,虽色泽各异,但骨子里均带黄味,这是田石泛称田黄的一个重要原因。田黄的各种称 谓是在产地、色泽基础上的称谓。如“上坂田”,即“上坂所产田黄”、“乌鸦皮”即“黑皮田黄”,“白田”即“泛白色的田黄”等。
    橘皮红田、色如红橘皮,即橘皮黄之最浓者,色艳似红,黄中泛红。产三坂田,鲜艳通明,萝卜纹细致入化,文举说“材积不盈两”,占田石产量比例最少,极为稀罕,故材、形俱佳者被列为田石极品。
    煨红田、表皮的一部份为枣红色,其它部份则泛黄,或带黑皮及黑斑,产于上、中坂田中,此为田父烧草积肥等人为原因至使土中小田黄受高热而产生变化的产物。一般质地坚硬、乾涩、无明显萝卜纹,材积极小,不为藏家所重,见有以作随形小印章者,印身刻巧色薄意,也可爱。
    橘皮黄田、色近橘皮红,略泛黄色。三坂田均产,以色泽取名,或有皮,或无皮,多有细密的萝卜纹,质嫩色浓,凝灵润洁,鲜艳通明之标准田黄。邓散木《篆刻学》记载清末田黄价值时说:“其橘皮黄,四方者,两以上,价三倍黄金。”实指此石。用此田作印章可显庄重而堂皇,见帝王气象。为田黄之上品。
    黄金黄田、以色泽取名,即橘子快成熟时其皮之金黄色,明快而灿烂。三坂田均产,或有皮、或无皮,萝卜纹细密而隐现,为黄中带赤的标准田黄。以此田作印章者,可显富贵而雍荣,有敌国巨派,为田黄之上品。
    枇杷黄田、色黄如枇杷色者,有浓浅二色,色浓者,较之黄金黄略带赭意,似桔皮黄,色浅者稍淡,香港、厦门等地人均喜此色,三坂田均产,以色取名。或有皮、或无皮,萝卜纹细密有致,温润可爱,气度典雅之标准田黄。以此田作印章者,端庄而显书卷气,乾隆皇帝不少御书玺印即用此田制成。为田黄之上品。
    桂花黄田、色如桂花,或浅枇把黄。三坂田均产,产碓下坂为多。以色相取名,较之枇杷黄田略淡而泛粉色,石皮或有、或无,萝卜纹或隐或现,色泽虽淡,仍娇艳无比,深受闺中人所爱,巾国夫人或大家闺秀多喜以之为印章,随身雅玩,庄重而清雅,据陈兴邦先生云,宋美龄的“宋氏”小玺即选桂花黄田。
    鸡油黄田、如鸡腹中之块状鸡油者,三坂田均产,以色质取名,灵腻而细嫩、石皮与萝卜纹如桂花田。制为印章,有隐现富贵之感。
    熟栗黄田、以色相取名,色如熟栗,三坂田均产,以制印章,庄重大雅,不失文豪气派。吴昌吉“一月安东令”印,即以此田为之。
    肥皂黄田、色如黄肥皂,较之熟栗黄色淡而滞腻。三坂田均产,有时皮略厚,时有杂质,通灵度也略差,上等肥皂黄田可列为田黄中下品,差者俗称杂田,曩见旧日文人常以之为印,究其原因,价廉而不失格调故也。
    糖粿黄田、以色、质取名,色泽黯褐而质如鹿目,三坂田均产,又如浙江临安之玉山山黄,多不通灵,然不失田黄韵味,多无石皮,或有少量石皮,一般无萝卜纹,时有少量杂纹,不明显。以之作印章,甚为大方,格调高于水坑山坑之石。价廉而能以别尊卑,为文人们欣羡之主要原因。
    蜜蜡黄田、色如蜂蜡,三坂田均产。以色、质取名,较之鸡油黄滞结,人称之为“蜜蜡”,因产量少未见之,旧日曾见一小印,见之愕然,不知其名,主人告之为“蜜蜡印”,索观之,果为蜜蜡黄田。
    蕃薯黄田、色近蕃薯,三坂田均产,以色、质取名,质燥凝,多无纹,不通灵。上等者可列为田黄中下品,差者为杂田。为印者甚多,也倍觉可爱。
    白田、白色田石,以上品者,色近羊脂玉,又似坑头白水晶而泛黄、泛红。多产上、中坂田。有格,似血缕,萝卜纹细致而鲜明。差者色白而浑浊,有白皮深入肌理。此田稀有为贵,旧日以此田为印章者多高官达贵,以显纯洁、清廉,多不注目,行家见之惊然。
金裹银田、白田有黄皮者,罕见。多产上、中坂田。甚名贵。曩在山西太谷见有陈巨来为孔祥熙所制小闲章。即此为之,黄皮薄意为林清卿雕。甚雅。
    黑田、黑色田石。或黑中泛赭,或黑中带灰,带灰常有黄皮肌质较其它田石粗,萝卜纹或粗而显,或细而密,产于三坂田,在铁头岭一带水田中居多。近于杂田,人们多以制不定形闲章者。
    绿田、青绿色田石。肌质细腻而透明,萝卜纹细密而有条理,旧日通常将其列为黑田之中,其实比黑田质优,但极罕见。近日见在善伯山下九手田一带有出土。
    乌鸦皮田、又称“蛤蟆皮田”,为田黄、白田外裹黑皮者,皮微透,略带绿灰,或青绿色,肌理多伴小黑钉,多产于下坂一带。制作印章以不定形闲章为好。
    银裹金田、以外白内黄两种色组成的田石,色泽明快淡雅,质纯净而细嫩,萝卜纹细密隐约,一般材积较小,制印多作不定形之闲章。

Yellowstone



    
Origin and Present

    
For Yellowstone or known as the " Osaka ", " in Osaka ", " Sakashita " in the past, people have been unable to Shen Jie , especially foreigners , are always vague in concept , for which the author was 72 years , 87 years , three to 98 years Shoushan Tianhuang origin were studied. 98 In that study , under the leadership of a friend , described in detail . Alpine foothills in the south of the village and outside Shou every sector of the ocean , a minor clean Xikou outflow from this creek creek known locally as the pit head . Xikou outflow from about five or six meters from the mountains on the west side between the shed and a large segment of the river confluence , the stream is Shoushan Creek confluence . Brook , the winding , Shoushan village from abroad bypassed , and the origin of oceanic Qishan Creek intersection. Interchange, a boulder in the river , the river suddenly face a narrow , fast-flowing , it was originally set waterwheel pestle meters here , so called " pestle under ." After the meter loop dragon, Sungai , vaginal discharge and slowly into the knot door Tan Lianjiang County territory . It will be produced stone brook paddy fields into upper, middle and lower three lots, commonly known as the " Osaka ." For this " Sakamoto " word , more than outsiders understand its meaning , or think there is any secret, in fact, meant lots and locations. Will be divided into areas Tianhuang Osaka, in Osaka , in Osaka, which is the local custom title. Man people under customary principles " from the local place names " and in the book, the public of the world , became the official title Tianhuang origin . The former head of a large segment of the pit with a large section of the river above the paddy Creek intersection , called on Sakamoto , a large segment of the Ocean Creek Interchange in this section of paddy called Osaka , then to under paddy pestle called Sakashita , from pestle tan said the door down to the end pestle Sakashita . In recent years, agriculture has the habit of Shoushan stone will be in Osaka , Osaka Xiabandi collectively in the past two decades produced according Tianhuang texture and business needs, pestle Sakashita said Sakashita . Sakamoto produced each stone were called Tian Tian on the plate , the plate and the lower plate Tian Tian .

    
Stone on the field in terms of production , according to records , in which " the birthplace of the head from the pit to the downstream junction gate Lake, total length of about seven or eight kilometers . Centuries , in this wide or narrow creek , with a total area of ​​not to one square kilometer of paddy fields have been producing a lot of precious gems Tianhuang . " However , that is such a small place of origin where , after hundreds of years of mining people in the Republic of China had " long-suppressed production of stone" rumors. After China's reform and opening up, Shoushan villagers as " treasure hunt" and set off two decades of mop- digging , digging in the past two decades , we can say is to put all of the Land can be dug and turned over several times heavy . Sometimes the village young and old together out day and night digging . The current situation is : In addition to lots of two acres in Osaka quarter , the ban by the local government to protect the dig , the other Tanaka even the little finger sized " Tianhuang earners" are exhausted from stone dug over with . Local farmers still kept digging stone , they will be extended to Osaka lots hillside , occasionally poor quality pieces can be dug field stone.

    
To distinguish the lot

    
Three fields produced by Tanaka Sakai stone slightly different , but this distinction is not fundamentally different , but the difference between color and texture appear on the same farm that is what the stone can be roughly separated according to the texture and color Sakamoto segment subtle changes produced .

    
On Sakata , produced in the Sakamoto , who was slightly lighter in color and more . Mr. Lin Wenju says: " Sakata quality on partial tender , delicate and translucent ," Mr. Fang Zongkui Yiyun: " pale and quality spirits , resembles the pit head crystal jelly ." Also produced dark brown color and the quality of concentrated deer head as miscellaneous class field , but also with the production of white and black of Wu Yapi Tin Tin .

    
In Sakata , Sakata lots produced in the paddy fields , mostly color, quality is superb, the color was thick and tender quality prolific standards Tianhuang . Also produced white skin Tin Tin and crows .

    
Under Sakata , Sakata under production lots, in the past gives the impression that the texture of condensate greasy, dark green color, dark , prolific field or tung oil to Kuroda , but later also produced a lot of texture and spirit through a superbly Tianhuang cold, the ground Tian Shi often produced with fine black spots.

    
- Pestle under Sakata , Sakata pestle under production lots, and multi- texture , although the spirit of hard tetrahedrite , even with dry peel ; yellow and reddish brown , thick outer layer of color to the inside and Qudan , radish pattern evident , delicate and slightly straight . More than a louse egg-shaped white spots . There is also a no skin , no carrot pattern, texture and tender, less crack grid texture psychic degrees less , the same color and the next Sakata , also contain lice ovate white spot on .

    
Pipe Creek field , in the house Banxi pipe unearthed near Sidi field stone, stone local farmers called " frozen brook " or " Pipe Creek Field Stone" or " river Sakamoto monolithic " excellent transparency . Experts believe that a swing and fall by flash floods washed stone Sidi Tian Tian Shi Yun-long water erosion by its appearance pan- yellow or dark ocher , stone doubly Ying Che . Throughout Shoushan Sidi even able to find .

    
Resting slipped fields, namely the local flow stone called " monkey flow field" , " slippery field ." And out of the ground ( scroll resting slip dialect meaning ) , farming plowing fields石经田father , torrential rain washed the transfer of field stone, often a part degraded by sunlight , Cuse becomes dry , straight lines and more biased , coarse . Pan-green color gray, yellow and less skin , muscles in the sand with black nails with white spots . In the three fields Sakamoto and river surface and pestle to return the dragon, Sungai , taken off the visible surface of the sand , stones in these fields can also be seen as a field stone dyed soy formula , or no pattern or like filamentous pattern, particularly fine .

    
Nine hand field, produced in primary pestle Sakashita perfection along the foot of Shoushan Creek deep in sand . Mining excavation difficult yield rare , Sidi earth and rock excavation shall pour Legend nine hands before being transported to the ground , or say , five people share , one person quarrying a broken hand , a total of nine left hand , hence the term . The field no pattern or texture or grain as fine as silk , leather and more thin , brown color has red, yellow and whitened there were . Texture psychic, occasionally sporadic black nails with white spots .

    
Hard fields, each produced by Sakamoto and poor muscle quality hard Tianhuang , Weaver green leather , quality leather such as deer head , even once the skin such as cattle , grain or no grain or grain dockage , poor and with a master psychic sand . Slightly better texture class in miscellaneous fields. The miscellaneous category also Tian poor "hard field ." No fixed standard, however hard field produced by the seal remains dignified character, when better than other rocks, because the case is hereby Tian Shi family , no rocks anger of the "Royal " grace period.

    
To distinguish color

    
Yellowstone color generally yellowish , whether it is white field, red field, Kuroda , green fields, silver wrapped in gold , crow leather , etc., although the color varies, but underneath all with yellow flavor, this is Tian Shi Pan said Tianhuang an important reasons. Tianhuang various appellation of origin is in the title , on the basis of color . Such as " on Sakata ," that " the Osaka produced Tianhuang ", " raven skin" or " black Tianhuang ", "white field" or " pan- white Tianhuang " and so on.

    
Orange red field , the color red orange peel , orange peel that is most concentrated by yellow , bright color like red, yellow and the red. Producing three Sakata , bright brightly lit , radishes into delicate lines of , Wenju say " no gain volume two ," Tin ore production accounted for the lowest percentage , is extremely rare , so the material , shape and taste were classified as field stone Need.

    
Simmer red field, a part of the epidermis is maroon , the other part of the yellowing , or with black and dark spots , produced in the upper, middle Sakamoto Tanaka , this is the father of burning grass fields and other man-made causes manure to make the soil Tianhuang heat generated by small changes in the product. General hard, dry , no carrot pattern, material positive small , collectors are heavy , and saw a small seal for those who are not with the shape of India skillfully carved body color thin meaning, too cute.

    
Orange Huangtian , near Orange color red, slightly yellowish . Three Sakata are produced to color name , or skin, with or without skin, more than a fine grain radishes , tender quality color thick , pour Yun Ling Jie, bright brightly standard tianhuang . Deng scattered wood " carving school ," records the value of the late Qing Tian Huang said: . " Its orange peel yellow , four persons , two or more, three times the price of gold" actually refers to this stone . With this Tianzuo seal can significantly solemn and stately , see emperors weather . Tianhuang the top grade .

    
Huang金黄田to color name , when that orange skin of its fast maturity yellow gold , bright and brilliant. Three Sakata are produced , or skin, with or without skin, fine lines and looming radishes , yellow with standard Tianhuang to deficit . This Tianzuo seal , could be significant wealth and Yung Wing , there are giant enemy faction , the top grade of Tianhuang .

    
Huangtian loquat , loquat yellow color as those who have concentrated shallow two -color , tinted who , compared with slightly golden yellow ocher meaning, like orange peel yellow, paler coloration by Hong Kong , Xiamen, and the per capita hi this color, three Sakata are produced to color name . Or skin, with or without skin, fine lines are caused by radish , gentle and lovely, elegant bearing standard tianhuang . Seal this Tianzuo who dignified and significant bookish , Emperor Qianlong that many Yushu Seals made ​​with this field . Tianhuang the top grade .

    
Osmanthus Huangtian , the color of sweet-scented osmanthus , or pale yellow loquat . Three Sakata are produced under production pestle Sakamoto as much. Named in Hue , calling on slightly lighter than loquat and pan pink, leather or stone , or none, or hidden or radish grain , color and light , though , is still very tender and beautiful , deeply human love boudoir , State or towel lady ladylike is more hi to seal , portable play ya , dignified and elegant, according to Mr. Chen Xingbang cloud shek 's " Soong " Little Xi Huang Tian Guihua that election .

    
Chanterelle Huangtian , such as those massive chicken chicken fat belly , the three Sakata are produced to color quality named , tired and delicate spirit , stone skin and radish grain , such as osmanthus fields. System for the seal, there is a sense of looming Fortunate .

    
Cooked chestnut Huangtian to Hue name , the color of cooked chestnut , three Sakata are produced to manufacture seal, solemn Taiga, losing writer style. Wu Changji " Jan Anton order" India , that this field whom .

    
Huangtian soap , soap colors such as yellow , pale yellow rather than cooked chestnut stagnation greasy. Three Sakata are produced , sometimes slightly thick skin when there are impurities , psychic degree also slightly worse, could be classified as the finest soap Huang Tian Tian Huang in low-grade , poor person , commonly known as hybrid field, snapped the old scholars often refer to them as India , The reason it is also inexpensive yet style .

    
Sugar cake Huangtian to color, quality name , color dark brown and quality such as deer head , three Sakata are produced , and if the Yushan Mountain Lin'an yellow, more is not psychic , and then losing Tianhuang charm , no more stone skin , or a small amount of stone skin , usually without radish pattern, when a small amount of miscellaneous grain , is not obvious. As to the seal , very generous, above the puddle Shankeng style of stone. Cheap and can not hierarchy, mainly due to the envy of the literati .

    
Huangtian beeswax color such as beeswax, three Sakata are produced . In color, quality named , yellow chanterelles than stagnation knot, called the " beeswax ", because no less yield , the old have seen a small print , see the stunned , I do not know his name , told the owner to " beeswax India" , claims of view , calling on the fruit of beeswax .

    
Huangtian sweet potatoes , yams color nearly three Sakata are produced in color, quality name , quality dry condensate , no more lines , not psychic . Fine may be classified as low-grade Tianhuang the poor by miscellaneous fields. To many Indian who also become far more lovely.

    
Tin, Tin white stone above product by color almost white jade , deemed the pit head and yellow crystal white , red. Prolific on the Sakata . There are cells, like blood thread , radish detailed and vivid patterns . With poor white and cloudy, there are white -depth texture . This field is rare and expensive, this field to seal the old officials were more expensive up to substantially pure, honest, and many do not attract attention , experts see the scared then .

壽山石與田黃石的正名 Naming of Shoushan stone and Yellowstone


壽山石的名稱據說是因原始產地福建省福州市壽山鄉而得名。
壽山石在化學分析下,有高嶺石、葉臘石、地開石...等許多不同的礦物組合礦石,有時又會含有不同含量的雲母、珍珠陶石而出現美麗的外觀。
石脈紋
在寶石學的研究,壽山石是屬於集合結晶體類的多晶質的一種,在寶石顯微鏡下,用光纖燈晃動照明觀察,有部份的壽山石會具有其特定的石脈紋,因為極似蘿蔔的絲狀紋路,有人就稱為蘿蔔絲,但並非所有的壽山石都具有此種紋路。
顏色
壽山石既然是屬於集合結晶體類,其顏色的變化程度,就端視其含有的結晶與致色元素,而出現多樣的變化,一般壽山石的顏色有,白色、灰色、黃色、紅色與黑色,大部份在玩石收藏市場上的壽山石顏色,是由淡黃色到較深的褐黃色,一般在金黃色與鮮紅的色調,是被認定為較受到大眾的喜愛,其市場價格也相對較高。
透明度
除了顏色以外,比較特殊的是壽山石的透明度變
化,許多壽山石在地層下成長蘊變時,因為本質的化學成分不同,以及接受的溫度、壓力與溼度不同,同一塊出土的壽山石,在不同的位置,經常會出現不同的透明程度,一般而言,透明度愈高,達到一定透光的程度,就會被稱為凍,這就會大大提升該壽山石的品質。
田黃石的定義
田黃石則是屬於壽山石的種類之ㄧ,市場上對田黃石的定義繁多,有紅色的紅田石、有黑色的黑田石,也有人定義田黃石必須具有一定的蘿蔔絲紋路...等,各路學說均有。
在寶石學所定義的田黃石,就是要先確認壽山石的身分,在確認其顏色的金黃色調程度、在光纖燈照射下,透明度為透光至半透明的程度時,就會在鑑定證書上以田黃石的種類開具,至於有沒有蘿蔔絲,則不會被包涵在定義的考量範圍中。
田黃石的產量不多,外觀美麗無比,加上高級的雕刻藝術,在市場上的價值不斐。
造假的壽山石與人工處理的方法
壽山石的硬度不高,一般石英類或鐵器就能輕易刮蝕,早期許多雕刻藝術師非常喜好用壽山石來雕刻成品,成為美麗的擺飾石種 ,而且每一塊出土的壽山石,顏色分佈與透明度都不一樣,塊塊都具有獨一性,非常作為送禮或收藏的物件。而且中國的許多傳統印章石材, 也是使用壽山石。
在雕刻壽山石時,經常因部份石材的完整性不夠,許多人使用強化的樹旨來黏補,由於科技的進步,現今的填補技術,很難由肉眼就能觀察出來。許多時候,由專業的師傅在填補處施以花紋工藝,或加以著色處理,就 成為一塊美麗的擺飾石。
但經過人工填補或著色的壽山石,時間一久就會呈現腿色或裂紋的現象, 尤其在擺設位置,經年累月用強光照射,更是加速樹旨亀裂的主要殺手,所以在選購壽山石或田黃石,對於這點要特別注意。
 
Shoushan Stone's name Shoushan stone is said to be due to the original name, Fuzhou, Fujian origin Shou Shan named.

 
Shoushan stone in chemical analysis, kaolinite, pyrophyllite, dickite ... and so many different combinations of mineral ores, and sometimes will contain different amounts of mica, pearl stone and pottery appear beautiful outward appearance. Veined stone

 
In the study of gemology, Shoushan stone is part of polycrystalline a collection of crystal class under gem microscope, with fiber optic lights shaking lighting observations, some of Shoushan stone will have its specific stone veins, because mimicking radish filamentous lines, someone called radish, but not all of the Shoushan stone has such lines. Color

 
Shoushan stone since it is part of a collection of crystal class, the extent of the color change, it depends which contains crystals and coloring element, the emergence of a variety of changes, general Shoushan stone colors, white, gray, yellow, red and black, most copies on playing rock collection market Shoushan stone color is from light yellow to deep brown-yellow, usually with red golden hue, is identified as representing adored by the masses, its market price is relatively high. Transparency

 
In addition to color, transparency rather special variant Shoushan Stone

 
Of many of Shoushan stone at formation growth Yun varying because of different chemical composition nature and acceptance of temperature, pressure and humidity is different, the same piece of unearthed Shoushan stone, in different locations, often appear different level of transparency, general and words, higher transparency, to a certain extent transparent, it will be called frozen, which will greatly enhance the quality of the Shoushan stone. The definition of Yellowstone

 
Yellowstone is part of ㄧ types of Shoushan stone, the definition of the market for many Yellowstone, red field with a red stone, with black stone Kuroda, it was also defined Yellowstone radish must have some lines ... and so on, and the brightest doctrines are.

 
In Yellowstone defined gemology, Shoushan stone is the first to confirm the identity, in confirming the extent of the golden hue of its color, in fiber optic light irradiation, transparency transparent to translucent extent, it will on the certificate of authenticity to Yellowstone species issue, as there is no radish, it will not be a consideration in the definition of bear range.

 
Yellowstone yield much, very beautiful appearance, coupled with advanced sculpture, valued in the market is not Fiji. Shoushan stone and artificial method of handling fraud

 
Hardness Shoushan stone is not high, usually quartz class or iron can easily scrape eclipse, many early sculpture art teacher is very like to use Shoushan stone to carve the finished product, to become beautiful ornaments stone types, and each piece unearthed Shoushan stone, color distribution and transparency are not the same, departments and regions have unique properties, as a gift or a collection of very object. And many of the traditional Chinese seal stone, but also the use of Shoushan stone.

 
Shoushan stone carving at the time, often because of the integrity of the part of the stone is not enough, many people use the tree aims to strengthen the sticky patch, due to advances in technology, today's filling technology, it can be observed by the naked eye is difficult. In many cases, imposed by a professional chef at the pattern in filling process, or be coloring treatment, it becomes a beautiful decoration stone.

 
But after artificial fill or colored Shoushan Stone, a long time will be showing color phenomenon leg or cracks, especially in the display position, long years with a bright light, but also accelerate the major killer of trees aimed tortoise crack, so in the purchase of Shoushan stone or Yellowstone, Pay particular attention to this point. ...

田黄石的收藏与鉴定 Collection and identification of Yellowstone

田黄石的收藏与鉴定

                  
  田黄是石中之王,自问世以来一直受到达官贵人、富商巨贾的追捧,而“黄金易得,田黄难求”,“一两田黄三两金”等民间说法也使田黄的尊贵地位得到凸显,甚至让田黄蒙上了一层神秘色彩。如今优质田黄早已以克论价,而一些料好、雕工出色的名家名作更是可遇而不可求了。
  所谓田黄,即寿山石中的特殊品种,因产于福建寿山村坑头溪两岸水田及河流底部的沙砾层中而得名。其质地细腻、温润,手摸有滑感,并常有石皮、红格、罗卜纹等标志。田黄作为我国特有的“软宝石”之一,在全世界范围内只有我国福建寿山一块不到1平方公里的田中出产,因此产量极其有限。需要注意的是,并非任何田黄都具有很高的收藏价值。田黄的质地优劣悬殊,价值高低差异极大,不能一概而论。多数用于收藏与投资的田黄也仅是其中少部分特征明显、各方面俱佳而无可挑剔的上品。因此,如何品鉴上品田黄石材或田黄印章就成为田黄初学者必须掌握的要领。田黄的鉴定标准上好的田黄首先颜色要正,所以田黄的“黄”就要求黄得如同金子般灿烂。上品的田黄还要通透、纯净、细腻,纹理要美。同时作为硬石的代表石材,田黄出土时均为椭圆形,所以上品的田黄应该饱满、浑圆、比例协调。当前的收藏界在辨别田黄上有三大标准,即“有萝卜丝纹、红筋、石皮”。值得注意的是,由于田黄石的品种、样貌多样,如果仅用这几个标准来衡量,难免会以偏概全。因此在鉴定田黄时,除了要观察以下一些常见特征,还要综合考虑质地、色泽等其他因素。
  1.石形
  田黄的母石为山料,呈棱角状,经过重力与水流的搬运及磨蚀作用,其棱角逐渐圆化,形成形态多样、大小不一的卵石(独石),呈次棱角状或次圆状。如果发现棱角尖锐或浑圆光滑的“田黄”就值得怀疑,可能为掘性石或山料磨制而成,但如果在加工过程中破坏了其原形就难以识别了。田黄一般为几十克至几百克,超过千克的非常罕见,几公斤的田黄应值得警惕。
  2.石皮
  田黄长期埋藏在水田中,经风化作用,其外表通常会形成不同特征的皮层。根据皮层的厚薄,可分为厚皮(>1mm)、薄皮(<1mm)和稀皮(细雾状);皮层有单层皮与多层皮。田黄的皮色主要有黄色、黑色与白色。黑色皮俗称“乌鸦皮”;皮为白色而石色为黄色,称为“银包金”;皮为黄色而石色为白色,称为“金包银”。田黄的不同皮色可能与不同颜色的土质有关,即黄色的土壤形成黄色皮,黑色的土壤形成黑色皮。由于田黄普遍发育石皮,有“无皮不成田”之说,故石皮成为鉴定田黄的重要特征之一。
  3.萝卜丝纹
  采用透射光观察田黄的内部,其普遍发育似“萝卜丝纹”纹理,是非常重要的鉴定特征。田黄内部的“萝卜丝纹”多种多样,发育程度不同,按粗细可分为条带状、条纹状与细丝状;按形态可分为直线形、网状形与不规则形;按颜色可分为白色、黄色与棕色;按透明度可分为半透明与微透明。田黄基本上都具有“萝卜丝纹”,“无纹不成田”的说法成立,但不能绝对化。
  4.红格(或红筋)
  田黄的“格”或“筋”实际上是一种裂隙,这些裂隙在地表条件下,特别是水田里,普遍受到Fe2O3溶液的渗入与沉淀,被染成黄红色,故称为红格或红筋。但也有少数没有颜色,为白色裂隙,则称为无色格。田黄有红格(或红筋)的现象较普遍,也有“无格不成田”之说。
  造假方法与真伪鉴别随着艺术品市场的升温和田黄价格的逐年提升,市场上出现了大量的田黄仿制品,种类之多、数量之大,严重影响了人们对于收藏的信心。田黄的造假方式越来越多,如何使其现出“原形”成为考验收藏者眼力的难题。
  1.冒充法
  该方法由来已久,主要用产于寿山一带的其他石种冒充田黄。这些石种的外观类似田黄,但其本身具有一些独特的特点,如鹿目格无“萝卜丝纹”而有“鸽眼砂”,溪蛋无“萝卜丝纹”和红格,牛蛋黄无“萝卜丝纹”且密度大。
  2.拼接法
  拼接法指将许多小块田黄(小于30g)拼接为大块田黄,并在拼接处以工艺手段掩盖其痕迹。这种拼接田黄的鉴别方法是:(1)寻找接合缝。接合缝一般用胶黏合,放大观察可看到胶的存在,或用热针试之会冒白烟;(2)内部的格纹特征。在强透射光下,可发现其内部的不同部分,红格和“萝卜丝纹”的形态不同,粗细与色调相差很大,还有突然断开、不连续等现象。
  3.塑料仿制法
  此法主要是用半透明的浅黄色塑料冒充田黄,其鉴别方法为:(1)外貌特征。颜色与质地较均匀,内外一致,无石皮;(2)内部特征。在强照射光下内部干净、均一,无红格、“萝卜丝纹”和杂质;(3)触感法。将其贴于面部有温感,天然田黄则为凉感;(4)手掂法。因塑料的密度远低于田黄,手掂轻;(5)刀刮法。用刀刮之,呈片状,而田黄则呈粉未状:(6)热针试验。用热针触之,冒白烟,散发塑料味。
  4.山石仿制法

  山石仿制法指利用各种蚀变型黏土类岩石依照田黄的颜色、石形、石皮等特征进行仿制。目前,这类田黄仿制品在市场上数量最大,由于其外观与田黄十分相似,其欺骗性也最大,使不少人上当受骗,鉴别时需结合仪器与感官分析。鉴别方法为:(1)测量石质。运用红外光谱仪等仪器对石质进行测试,以确定其主要矿物组成以及样品的密度。(2)观察石形。山石仿造的田黄砾石形态通常为单调的浑圆状,表面光溜,缺少天然田黄表面的大小不规则状凹坑与沟槽。(3)观察石皮。仿制的石皮质地较干涩,皮色较鲜艳、均一,不自然;而天然石皮质地较细滑,色泽较柔和,颜色不十分均匀,非常自然。(4)观察石色。经染色处理的田黄仿制品总体上颜色较均一,有些过于鲜艳,有些过于色浓,不够柔和




Collection and identification of Yellowstone
   
 
 
Tianhuang is the king of rock, since its inception has been dignitaries, wealthy businessmen sought after, and "easy to get gold, Tianhuang hard to find," "one or two tianhuang couple of gold" and other folk saying also distinguished Tianhuang status has been highlighted, and even Tianhuang cast a mystery. Today, high-quality grams Lunjia Tianhuang long, and some good material, excellent workmanship and famous masterpieces is scarce it.
The so-called Tianhuang that Shoushan stone in special varieties, as produced in Fujian Shou gravel pit village head strait Paddy Creek and named after the river bottom. Its fine texture, moist, slippery hand touch feeling, and often stone skin, red cells, carrots lines and other signs. Tianhuang as one of the "soft gem" of a unique, worldwide only a piece of China's Fujian Shoushan Tanaka produced less than one square kilometer, so production is extremely limited. It should be noted that not any Tianhuang have a high collection value. Tianhuang texture merits of the poor, high and low values ​​vary greatly and can not be generalized. Tianhuang mostly for collection and investment also is one of only a small number of distinctive characteristics, all aspects of impeccable taste and top grade. So how Tianhuang tasting top grade stone or tianhuang seal became tianhuang beginners must master the essentials. The identification of good standard Tianhuang Tianhuang first color to be positive, so Tianhuang "yellow" requires Huang as bright as gold. Top grade Tianhuang also transparent, pure, delicate texture to the United States. At the same stone as the Hard Rock's behalf, are unearthed when Tianhuang oval, so the top grade Tianhuang should be plump, rounded, the proportion of coordination. The current collectors in identifying three criteria Tianhuang there, that "there is Luobosiwen, red bars, stone skin." It is worth noting that, due to the variety Yellowstone, diverse faces, if only these standards, they will be generalized. Therefore, when the identification Tianhuang, in addition to observe the following are some common characteristics, but also considering other factors, texture, color and so on.
1 stone shape
Tianhuang mother stone mountain material, was angular, after handling and abrasive action of gravity and flow, its rounded edges and gradually form varied shapes and sizes of pebbles (monolith), was sub-angular or sub-round shape. If it is found sharp or rounded edges and smooth "Tianhuang" is questionable, excavation of rock or may grinding material from the mountain, its original shape if the damage in the process would be difficult to identify it. Tianhuang usually tens of grams to hundreds of grams, more than one thousand grams of very rare, a few kilograms of Tianhuang should be vigilant.
2 stone skin
Tianhuang long buried in the paddy fields, through weathering, its appearance is usually characterized by the formation of different cortical. According to the thickness of the cortex can be divided into thick (> 1mm), thin (<1mm) and dilute skin (fine mist); cortex single and multi-skin leather. Tianhuang skin color are mainly yellow, black and white. Black leather commonly known as "crow skin"; skin color is white and yellow stone, called "wallets gold"; skin color is yellow and white stone, known as the "Gold Package Silver." Tianhuang different skin color and different colors may be related to soil, yellow soil that formed yellow skin, black leather black soil formation. Due to widespread development Tianhuang stone skin, there is "no skin is not a field," said the stone skin and therefore become an important characterization Tianhuang.
3 Luobosiwen
Identification by transmission characteristics of the light is very important to observe the internal Tianhuang, the general development like "Luobosiwen" texture is. Tianhuang internal "Luobosiwen" variety, different levels of development, can be divided by the thickness of the strip, stripes and filamentous; press can be divided into linear form, mesh-shaped and irregular in shape; Press Color can be divided into white, yellow and brown; press and transparency can be divided into semi-micro and transparent. Tianhuang basically have a "Luobosiwen", "no pattern fails field," saying the establishment, but not absolute.
4 red cell (or red bars)
Tianhuang "grid" or "bar" is actually a fissure, these cracks in the surface conditions, especially paddy fields, generally subject to infiltration and precipitation Fe2O3 solution was dyed red and yellow, it is known as red cells or red bars. But there are a few no color, white fissures, then known as colorless grid. Tianhuang red cells (or red bars) phenomenon more common, there are "no grid is not a field," said.
Fraud methods and the authenticity of identification with the art market increased year by year warming and Tianhuang prices, appeared on the market a lot of Tianhuang imitation, many species, the number of large, serious impact on people's confidence in the collection. Tianhuang false way more and more, how it emerged, "prototype" has become a test of collectors eyesight problems.
1. Posing Act
The time-honored method, mainly produced in other stone posing tianhuang Shoushan area. These stone kind of looks like Tianhuang, but it itself has some unique features, such as deer mesh grid without "Luobosiwen" and the "pigeon eye sand" Creek egg-free "Luobosiwen" and red cells, cow egg yolk No "Luobosiwen" and the density.
2 splicing
Splicing method refers to the many small tianhuang (less than 30g) for bulk Tianhuang stitching and stitching impose technical means to conceal their traces. This method of identifying splice Tianhuang are: (1) Find the joint seam. Adhesive bonding glue joints generally, the presence of gum magnified observation can be seen, or to be white smoke test of the hot needle; (2) Check the internal features. In strong transmitted light, can be found in different parts of its internal, red cell and "Luobosiwen" form different thickness and tone vary greatly, there suddenly disconnected, discontinuous phenomenon.
3 plastic imitation Act
This method is mainly used pale yellow translucent plastic posing Tianhuang, its identification methods are: (1) physical characteristics. Color and texture more uniform, consistent and outside, no stone skin; (2) internal features. In strong light irradiation inside a clean, uniform, no red cells, "Luobosiwen" and impurities; (3) touch method. Be affixed to the face with warm feeling, a sense of natural Tianhuang was cool; (4) Hand weigh method. Due to much lower than the density of plastic Tianhuang hand weigh light; (5) Knife Act. Daogua of use, flaky, and then was powdered Tianhuang: (6) hot needle test. Touch with hot needle, white smoke, distribute plastic taste.
4 rocks generic method
Generic means using a variety of rocks Act clay alteration type rocks accordance Tianhuang colors, stone shape, stone imitation leather and other features. At present, such Tianhuang imitations on the market the largest number, because of its appearance and Tianhuang very similar, is also the largest of its deceptive, so many people deceived, to be combined with the differential instrumentation and sensory analysis. Identification method: (a) measuring the stone. Using an infrared spectrometer instrument on the stone tested to determine its main mineral composition and density of the sample. (2) observe the stone shape. Tianhuang gravel rocks form of imitation is usually monotonous round shape, surface Guangliu lack of size natural Tianhuang irregular surface pits and trenches. (3) observe the stone skin. Imitation stone cortex than, dryness, skin color more vivid, uniform and unnatural; rather than the natural stone to smooth leather, softer color, color is not very uniform, very natural. (4) observation of stone colors. Tianhuang dyed imitation processed more uniform overall color, a little too bright, a little too tinted, not soft
