钙化或者腐蚀严重的是最难以鉴别的，所以也是很多高仿者所惯用的手法，从后几件藏品看现代工艺明显。兄不防先从玉质相对干净的玉件入手。[em27]

有干净的.呵呵!明天上几个很干净的!

      昨天上了几个都被疑为新工.几个小猪龙及其兽面坐人均没盘玩.即使盘玩过的高古玉也是在工下或解理处不停的有出灰状态.大家多次谈到工新.我想作为高古玉的辨别.首先应着眼于玉

 

质的老化与解理.如果玉质表面解理及老化明显及正常.工也就自然无疑.红山文化的工大部分为粗细瓦沟纹及粗的阴刻线.这种工艺现仿完全可以做出.并无太大难度.包括玉上解玉砂的痕迹.

 

唯一不能仿的是玉的自然老化现象.包括神韵.但神韵一说因人之主观感觉及审美及认识差异.而失之千里.我想我之上的藏品被认新工.应该出自如下几条观感:一:看到有工艺痕迹下有白色与

 

周边玉质包浆色彩光泽不一致.(因其没有多加盘玩.工下有些地方呈出灰状态).二:工痕迹转折处硬挺,感觉生硬,无圆滑感.(边角棱边会因色彩差异造成过渡欠缺.而且据我观察红山器物有些

 

棱口.洞口打的非常坚锐.).三:猪龙决口处太过平整.看不到拉锯痕迹.(细察决品处是有工艺痕迹残留.红山文化的决口开片分为线锯,片锯.砣锯.不一.并且切开后.多仔细打磨过).还有人怀疑

 

为老玉新工.如果首先承认此为老玉,有沁及自然状态的老化现象.那么新工必看其是否为玉上新刻的痕迹.即会刻断沁像.打断蚀洞.老玉新工.也会因重新造型,打磨,抛光而使沁成为无根之空

 

中楼阁.仔细辨识应不难发现破绽.

 

     有兄提及现高仿者多有仿钙化及蚀者重者.其实古玩各行无不被仿品侵扰.钙化之器固难于鉴别.但宏观上来看.与其有玉质之古玉是一个道理.终是玉质之后天之变异.玉表之裂,之次,之留.

 

之沁脉沁像因都有根可寻.仿者沁蚀同一,混浊不清,短期高压高温.酸咬火烤均破坏玉之原晶体.造成晶体而破裂.继而造成光泽失常,玉内正常之玉纹零乱不堪.细察之下应能发现破绽于一,

 

二.......

 

     今天上几个盘玩过.并玉质保存完好的.但工下仍有白色出灰状态.供议!
