石礦（上常尺反釋名云山體曰石下古猛反切韻金玉璞也說文未鍊金也從石廣聲有作𨥥紫𨥥藥名也經文從金廣作鑛俗用字也）。

Mineral ore (shikuang 石礦: the first character has the fanqie [reading] chang + chi [shi]. The Shiming says: "The substance of a mountain is called stone." The second character has the fanqie [reading] gu + meng [kuang]. The Qieyun says: "Uncut stone containing gold or jade." The Shuowen [jiezi] says: "Unrefined metal." It takes 'stone' [as semantic component] and guang as phonetic. It is also written 𨥥; purple mineral ore is a medicinal name. In the text of the scripture it is written with 'metal' and guang as 鑛, which is a vulgar character in use).
