This kind of phenomenon is different from modern polish with a high-speed polish tool. This is an important factor to be considered in Chinese antique authentication.IMG-3541

 

玻璃光是指玉器表面存在的一種硬朗、光亮如鏡的光澤,並非指該玉器的光澤與玻璃的光澤一致。有玻璃光的玉器,琢玉必定相當精美,其表面分外平整,光潔亮麗,反光明顯,與普通玉器的柔和光澤明顯不同。玻璃光的形成原因,主要是精細的打磨拋光,同時在地下埋藏千年,無氧的環境下形成。同時,玻璃光常出現在新疆和田玉中,玉質好,如果是地方玉,則基本不會出現玻璃光,良渚文化玉器除外。玻璃光玉器,儘量不要上手把玩,尤其汗手,容易破壞玻璃光氣。158803427462061032

目前,玻璃光無法仿製,因為玻璃光本身並非拋光形成,所以脫離了埋葬環境,是很難再還原玻璃光的。
