礬
U+792C "礬" CJK Unified Ideograph-# is a Chinese character that primarily refers to "alum," a crystalline substance used historically in dyeing, water purification, and medicine, as well as in the process of tanning and as a food additive. Composed of the radical for "stone" (石) and a phonetic component, this ideograph is pronounced "fán" in Mandarin and carries meanings related to vitriol or astringent mineral salts. Beyond its literal chemical sense, the character also appears in classical texts and compound words describing various types of mineral-based astringents or salts used in traditional East Asian crafts and pharmacology.
