矸石（上寒幹反考聲云矸玉石白貌也亦作矸又音千旱反律文從禾作秆非也）。

White stone (矸石: the first is pronounced with the fanqie 寒幹. The Kaosheng says: "Gān [矸] is the white appearance of jade or stone." Also written 矸; another pronunciation has the fanqie 千旱. In the Vinaya text it is written with grain [禾] as 秆, which is incorrect).
