雞血石之十二 (Chicken blood stone example 12)

昌化鸡血石收藏已经有2000多年的历史,近几年来,随着收藏热和需求量的增加,鸡血石的价格更是水涨船高,成为拍卖市场上的宠儿。2007年,一件著名雕刻大师牛克思雕琢的"昌化鸡血石雕楼阁山子"在北京翰海秋拍中以1344万元成交;2011年西泠春拍,一件血色艳红的巴林鸡血石摆件以1207.5万元成交。
        不过今年以来,中低端鸡血石市场出现了量价齐跌的现象。对此,鸡血石藏家杨华说:"有人说鸡血石3年涨了10倍,其实这种说法有炒作之嫌,只有大红袍鸡血石这样的稀有品种出现了大幅的增值,那些普通鸡血石的市场价格没有出现暴涨的情形,而是比较平缓的增长。”
        今年以来,艺术品市场整体不景气,除了个别精品之外,大部分鸡血石的价格都有所下跌。对比去年底到今年初期的高价,鸡血石的跌幅已经超过了30%,且交易量也有所下滑。特别是品相好的精品鸡血石都在藏家手里,市场低迷的时候,他们大都以观望为主,不会轻易出手。
        其实这几年,精品鸡血石的数量和质量都大不如从前,但是另一方面价格却居高不下,这也是不合理的。如今对那些想买高端鸡血石印章的普通藏家来说,可能有点儿晚了。资源匮乏价格飞涨,各种鸡血石作伪也应运而生,市场中充斥着各种假石头。比较常见的造假手法包括镶嵌染色、浸渍、贴皮法等。
镶嵌染色是指选用比较好的昌化鸡血石印章,在其表面挖出一些深深浅浅的小坑,然后用红色的硫化汞嵌入上色,再经过自然阴干后,打磨上蜡。不过这种经过镶嵌染色的鸡血石色泽生硬,没有层次感,比较容易辨识。
        也有直接将没有血色的昌化石,涂抹硫化汞后阴干再涂红色颜料,再阴干,然后放在树脂里浸渍。直接涂抹红色颜料的造假,其血色比较有层次感,但容易老化,表皮易泛黄。在产地,一些边角料、废弃料也充当上好的鸡血石,有的以假石料染上工业颜料冒充鸡血石,还有将粉碎的石粉添加工业染料再塑进行造假的。
        另一种能够以假乱真的作伪树脂合成法,使用矿物岩粉、胶、树脂和红色颜料,人工制成鸡血石纹路,经过高温、高压、打磨、抛光之后,逼真的鸡血石印章就做成了。这种合成鸡血石与真料相似,即便是有经验的藏家也难辨别真伪。当然也并非完全无法辨别,其化学成分特殊,燃烧的时候会有味道,会变色。
        真石贴皮法:造假者把真鸡血石的6面,切割出很薄的6片来包在普通石头上,把胶合处线角磨光。这种假鸡血石,血色自然,纹理分布有天然鸡血石的特性,非常难辨别。在鉴别时仔细观察四条接口看纹路是否能够衔接上。为了利益最大化,造假者往往是一块石头使用一个切割面,而诱人的血色也只能停留在一个平面上。
         拼接造假法大多出现在大型鸡血石雕件上。大型鸡血石原料很难一见,再加上精美的雕工,所以价格比较昂贵,造假者将鸡血石的血色部分镶注在大石头中,做成大型鸡血石摆件欺骗藏家。辨别大型鸡血石摆件时可以观察其纹路走向是否自然合理。
        投资收藏鸡血石首先要看血色,其次是质地。昌化鸡血石以血色浓郁而著称。红色越集中越有收藏价值,血色的面积要大,鲜艳欲滴。现在一方拇指大小、血色占石面面积40%的鸡血石印章,市场行情就在万元左右。其次要看质地,石质要洁净少杂质,手感细润,从质地上来看,羊脂冻最为珍贵,乌冻其次。
 
Chicken blood stone collection has 2,000 years of history, in recent years, with the collection of heat and increased demand, the price is rising Soapstone has become the darling of the auction market. In 2007, a famous sculptor carved cow Marx "Bloodstone pavilion mountain carving child" autumn auction in Beijing Hanhai to 13.44 million yuan turnover; 2011 Xiling spring auction, a bloody red ornaments to 1207.5 Bahrain Soapstonemillion deal. 
        
But this year, the low-end market in the Bloodstone volume and price down phenomenon. In this regard, Yang Hua, Bloodstone collectors, said: "Some people say Bloodstone three years up 10 times, in fact, there is speculation that this argument is suspected, only Dahongpao Bloodstone this rare species has shown a substantial appreciation in the market price of those of ordinary Bloodstone No case of spikes, but relatively flat growth. " 
        
This year, the overall downturn in the art market, in addition to individual boutique, most Bloodstone prices have dropped. Early this year compared to last year's high prices, Bloodstone decline has exceeded 30%, and the trading volume has declined.Especially good friend of the boutique soapstone are collectors hands, the market downturn, most of them to wait and see, will not easily shot. 
        
In fact, in recent years, the quantity and quality boutique Bloodstone are earlier than ever before, but then the price is high, it is unreasonable. Today, for those who want to buy a high-end soapstone seal ordinary collectors, it may be a little late. Resource scarcity prices soaring, a variety of soapstone fake have emerged, the market is flooded with a variety of fake stones. More common fraud practices include mosaic stained, impregnated, skinning method. Mosaic staining is a better choice Bloodstone seal on its surface a number of deep and shallow pits dug, and then embedded with red mercury sulfide color, and then through natural dried, polish wax. However, this color after soapstone mosaic stained blunt, no layering, relatively easy to identify. 
        
There will be no direct fossil bloodless Chang, smear mercury sulfide Reapply after dry red pigment, and then dried, and then placed in a resin impregnation. Direct smear red pigment fraud, its color more layered, but easy to aging, skin yellowing. In origin, some of the scrap, waste material also acts on a good heliotrope, some with fake stone pigment dyed posing soapstone industry, as well as adding the crushed powder for industrial dye remodeling fraud. 
        
Another believable fake resin synthesis, the use of mineral rock powder, plastic, resin and red pigments, artificial lines made of soapstone, high temperature, high pressure, grinding, polishing, the realistic soapstone seal it completed. This synthetic material similar to soapstone and true, even experienced collectors are also difficult to identify the authenticity. Of course, not entirely unable to distinguish its special chemical composition, when there will be burning taste will change. 
        
Real stone veneer law: the true Bloodstone counterfeiters 6 faces, cutting out the thin 6 to pack in an ordinary stone, place the glue line angle polished. This fake bloodstone, natural color, texture distribution characteristics of natural soapstone, very difficult to identify. In the identification of four carefully observed when the interface is able to see the lines converge on. In order to maximize the benefits of a stone counterfeiters often use a cutting surface, and attractive color can only stay on a plane. 
         
Stitching fraud law mostly in large soapstone carving member. Difficult to see a large soapstone raw materials, coupled with exquisite carving, so the price is more expensive, counterfeiters will Bloodstone Bloody part in the big stone inlay Note, made large soapstone ornaments deceive collectors. Identify large soapstone ornaments can be observed when the texture is natural and reasonable to. 
        
Bloodstone Bloody investment collection first look, followed by texture. Bloodstone to Scarlet rich and celebrated. The more red the more centralized collection value, bloody area is big, bright and dripping. Now one thumb size, color stone surface area accounted for 40% of the soapstone seal, the market in the yuan. Followed depends on the texture, stone less to clean impurities, feel nourish, from the texture point of view, the most precious suet frozen, freeze followed by Ukraine
