Experimental Research on Counterfeit Methods of White Soak-induced Colour of Ancient Jade

摘要: 为了验证现代常用的古玉白沁作伪方法的可行性,对市场上常见的作伪方法进行了验证实验,得到了作伪效果最佳的实验方法,为鉴定古玉白沁提供一定的理论依据,并初步探讨了古玉白沁的成因。实验以闪石玉和蛇纹石玉为原料,采用酸处理、碱处理和热处理等方法分别对样品进行了实验研究。结果表明,采用氢氟酸溅洒法和蜡封斑沁法可达到白色斑沁的效果,采用碱处理法伪作沁色的效果不明显,采用高温热处理方法的效果较理想。对比伪作玉器样品与真品古玉的白沁特征发现,酸处理样品的表面可见均匀分布的蚀坑;碱处理样品有似霜状白沁浮于其表面;热处理样品的表面局部存在火烧裂痕,加热至1000℃时稳定物相为辉石类矿物。Abstract: In order to validate the common counterfeit methods of the white soak-induced colour of the ancient jade,the counterfeit methods of the ancient jade on market are studied by the experiments and the best experiment method is gotten for the counterfeit,providing the theoretical foundations for their identification.The formation of the white soak-induced colour of the ancient jade is also preliminarily inquired.The raw material samples of amphibole and serpentine are experimented with the acid treatment,alkali treatment and high-temperature treatment.The results show that the way of spattering hydro-fluoric on the jade and soaking the jade partly with wax is proved to be feasible;but the jade treated with alkali could not get the obvious result;the high-temperature treatment method is proved to be ideal for counterfeiting the white soak-induced colour of the ancient jade.The comparision of the white soak-induced colour characteritics between the pseudograph samples and the real ancient jades shows that some corrosive holes are equably distributed on the surface of the samples treated with acid;the frost-like white soak-induced colour is on the surface of the samples treated with alkali;and some cracks caused by fire partly occur on the surface of the samples by heated treatment.The pyroxene is the stabilization species when heated to 1000℃.
