Text symbol

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.

Why does 礬 show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
