SURFACE TEXTURE OF JADEITE JADE ARTICLE

摘要: 经系统研究发现, 具粒状变晶结构的翡翠玉件的表面或多或少存在一些特殊的微观形貌, 它们是一定内部结构、构造在不同加工条件下的必然反映, 即表面组构。玉件表面的碎裂形貌有原生或后生碎裂结构、机械剥离结构和酸洗腐蚀结构 3种成因。它们各具特征, 但因彼此有成因联系, 有时也十分相似。特别是酸蚀后的碎裂部位是胶质物最主要的潜在赋存空间。在注胶工艺相同的条件下, 胶的显著程度主要取决于碎裂部位的形态、大小、多少及分布。Abstract: It is discovered by systematic studies that there exist, more or less, some special tangible shapes on the surface of jadeite jade article with granular crystalloblast. They are the natural reflection in certain internal constitutions which were formed under diffenent remaking conditions. The cataclastic part on the surface of jadeite jade article may fall into three origins: primary/epigenetic cataclasis, mechanical abrasion and acid washing erosion. They have their own characters though sometimes they look similar due to their close genetic relationship. In particular, the cataclastic part after the acid erosion is latent space of glutinonus filler material. Under the same conditions of glutinous filler technology, the degree of filler depends mainly on the shape of cataclastic part, its size, amount and distribution.
