鍮石（上音偷埤蒼云鍮石似金而非金也西域以藥鍊銅所成有二種鍮石善惡不等惡者挍白為灰折善者挍黃名為金折亦名真鍮俗云不博金是）。

Brass stone [鍮石] (The first character is pronounced 偷; the Picang says: "Toushi resembles gold, but is not gold; in the Western Regions it is created by smelting copper with chemical ingredients; there are two grades of brass stone of differing quality: the inferior kind is white and called ash-fracture, while the superior kind is yellow and called gold-fracture; it is also named true brass, commonly called non-fading gold").
