关于琉璃,据古代文献与实物对照,一般有三种解释:一是指某些天然的有光泽的宝石(如水晶石之类);二是指某种人造矿物质的有色半透明体物料(犹如今天的玻璃料器类);三是指附着于陶胎的面层彩釉。如今一般采用第三种说法。附着琉璃釉的陶瓦便谓之琉璃瓦。古代“琉璃”二字也写作流离、瑙璃、流璃……等等,据说是形容其耀眼生辉、流光陆离之意。关于第一种解释,有文献可循。《汉书·西域传上》:“罽宾国……出珠矶、珊瑚、虎魄、壁、流离。”注引孟康的说法“流离青色如玉。” Regarding the glass, according to the ancient literature and the physical object, there are generally three explanations: one is that some natural glossy gemstones (such as crystal stone) and the other is a colored translucent body material of a certain artificial mineral (as if Today’s glassware category); three refers to the surface layer of glaze attached to the ceramic. The third argument is generally used today. The terracotta with glazed glaze is called glazed tile. The ancient “glazed ” word was also written in terms of estrangement, glass, glass, and so on. It is said to describe its brilliance and brilliance. Regarding the first explanation, there is literature to follow. “Han Xi Shi Chuan Shang”: “Lou Binguo...beads, coral, tigers, walls, and exiles.” It was quoted by Meng Kang as saying, “Remote blue.”
