第35卷第2期超硬材料工程Vol.352023年4月SUPERHARDMATERIALENGINEERINGApr.,2023和田玉手镯浸无色油实验初探熊燕,徐志,魏保红(广东省珠宝玉石及贵金属检测中心,广东广州510080)摘要:通过对市场上两只手镯样品进行常规的宝石学测试、红外吸收光谱测试,发现这两只手镯均为和田玉,且都经过了浸无色油的优化方法。通过对其中一只手镯N-1浸无色油实验,对比实验前后的手镯N-1的外观差异,结果显示,和田玉手镯N-1是经过了浸无色油的优化方法,油析出之后,手镯N-1里原本就存在的白色棉絮显露出来。将手镯N-1在一定的温度条件下浸无色油,油充填了矿物之间的间隙,即而看不到手镯里的白色棉絮。浸无色油能很有效地改善和田玉手镯的外观,使和田玉手镯看起来更油润更漂亮,但效果不是很稳定,需要反复浸无色油。关键词:和田玉;红外光谱;浸无色油中图分类号:TS933文献标识码:A文章编号:1673-1433(2023)02-0057-04PreliminarystudyontheexperimentofnephritebraceletsoakedincolorlessoilXIONGYan,XUZhi,WEIBaohong(GuangdongProvincialGem&PreciousMetalTestingCentre,Guangzhou510080,China)Abstract:Throughtheroutinegemmologytestandinfraredabsorptionspectrumtestoftwobraceletsonthemarket,itisshownthatthesetwobraceletsarenephrite,andbothofthemhavebeenoptimizedbybeingsoakedincolorlessoil.OneofthebraceletsN-1issoakedincolorlessoil,andtheappearancedifferenceofthebraceletN-1arecomparedbe-foreandaftertheexperiment.TheexperimentalresultshowsthatnephritebraceletN-1isoptimizedbybeingsoakedincolorlessoil.Aftertheoilisseparatedout,thewhitecottonwooloriginallyexistedinthebraceletN-1isexposed.TosoakthebraceletN-1incolor-lessoilatacertaintemperature,theoilfillsthegapbetweenminerals,sothewhitecot-tonwoolcannotbeseeninthebracelet.Soakingcolorlessoilcaneffectivelyimprovetheappearanceofnephritebracelet,makingitlookmoreoilyandbeautiful.Buttheeffectisnotverystable,anditneedstobesoakedrepeatedlyincolorlessoil.Keywords:nephrite,infraredspectrum,soakedincolorlessoil近日,笔者在广州某市场看到了两只灰白色手镯,据商家介绍,这两只手镯是同一批次的青海和田玉料子,当时采购时,外观相似,其中一只手镯已出售,然而消费者在佩戴一个多月后,手镯出现了非常明显的白色棉絮;而一直放在店里的另外一只手镯却无明显变化...
