What 礬 means
It names alum and related mineral salts. A Chinese dictionary called 玉篇, written after the earlier dictionary 說文, defines 礬 as a kind of stone.
The Song History, a Chinese historical chronicle, lists white and green alum among goods that were made, traded, and regulated. In 明礬, the surrounding character narrows the meaning to alum; 山礬 is a flowering plant's name. In Japanese usage, 礬水 is a mixture of alum and glue used to prepare paper or silk surfaces.
