摘要
对玛瑙的染黄色工艺进行探讨 ,使用 Fe(NO3) 3等试剂浸泡灰白色玛瑙后 ,再经过适当的加热处理 (2 10℃ ,3h) ,得到了颜色较鲜艳的黄色玛瑙。文中详细讨论了染色的机理、过程以及影响因素 ;并通过对比实验分析了染色的试剂中使用 KMn O4 具有明显的效果 ,指出热处理关键是对温度的控制。
White or light gray agates were dipped in reagents as Fe(NO 3) 3 , HC1 et al ,then was heated up slowly to 210℃ for 3 hours. After cooling naturally, the white or light gray agates had been changed color to bright yellow. The coloring mechanism, progress and influencing factors are included. At the later part of this paper ,the KMnO 4′s important role in coloring progress is discussed.
