（精）古玉学步（79）：高清大图赏辨良渚真仿阴刻线
一夫之

5000年多前的良渚玉器，1毫米内刻画了3到5条线。

用的什么工具？肉眼如何微雕？简直不可思议，至今仍然是谜。所以良渚阴刻线依然是神秘的（图1）。

都不知其所以然，所以在这些神器面前，可能任何语言都显得多余，静下心来，静静欣赏馆藏良渚器所含藏的韵味吧（图2）。

除了惊奇还是惊奇，1毫米内刻画了3到5条线，用的什么工具？书上说“用一种尖锐器”，是什么样的尖锐器，后世传说中的“昆吾刀”吗？（田园玉翁注：昆吾刀是完全扯淡的事）件件是名副其实的微雕，在没有显微镜的上古，肉眼如何刻线接续相续还条条不乱？或者，远古的视觉异常敏锐，后代人类的视力逐步退化啦（现代人类由于手机电脑电视的原因视力肯定在急速退化无疑）？

从良渚玉器阴刻线辨伪角度来看，仅仅感叹还不行，还要从更加细微处加以认识。以下是馆藏良渚玉器阴刻线碾琢痕迹的微距成像图片（图3）。

通过细微观察，应该能有一个初步的认知了，以下逐步加倍放大图，其镜头下的阴刻线工痕一览无余（图4），阴刻线槽底的剐蹭痕迹依稀可见。

欣赏馆藏的目的是为了求真辨伪，那么如下的良渚还是良渚（图5）吗？（田园玉翁注：以下这些，最大的破绽是包浆，阴线槽底的包浆不够）
