处理翡翠玉件B货鉴别──胶质充填物的判断

DISCRIMINATION OF A TREATED JADEITE (CLASS B)——JUDGED FROM THE COLLOIDAL FILLINGS

通过系统研究，认为正确检测判断胶质充填物是正确判断处理翡翠玉件Ｂ货的关键，也是唯一准则。聚合物（胶）充填出现在翡翠玉件的松弛部位，而玉件表面的松弛形貌绝非漂白优化处理单一成因，相应其充填物也绝非聚合物（胶）一种。要正确鉴别聚合物（胶），必须对玉件表面松弛部位充填物有全面地了解。鉴定时必须通过显微放大观察、针探测试、微区组分鉴别等方法系统研究，区分其充填物是原生充填，或是异常（加工）充填型（充胶），或是正常（加工）充填型。经过观察、测试区别确定其充填物为异常（加工）充填型（充胶），即可认定其玉件为处理翡翠Ｂ货。必要时再进行红外光谱测试验证。

A systematic study shows that to detect and judge the colloidal fillings accurately is the key to judge a treated jadeite(Class B) accurately and is the only criterion. Colloidal fillings exist in the flaccid parts of a jadeite, but the flaccid appearance on the surface of the jadeite is not absolutely the only origin of the optimum bleaching treatment. Correspondingly , its fillings are not absolutely only one kind. In order to discriminate the colloids correctly, one must find out the fillings in the flaccid parts on the surface of the jadeite comprehensively. When appraising the jadeite, one must distinguish among the primary , abnormal (processed) and normal (processed) filled colloids through a systematic study by observing with a microscope, testing with a needle and discriminating the microarea compositions. If the fillings are determined as abnormal (processed) filled colloids through observation, test and discrimination, the jadeite is a treated one (Class B). If necessary, a further infrared spectroscopic analysis can be made to confirm it.
