U+70BB "炻" CJK Unified Ideograph-# Unicode Character

U+70BB "炻" CJK Unified Ideograph-# is a Chinese character (Hanzi) that primarily refers to a type of stoneware or a kind of hard, fired ceramic material, often associated with a vitrified or stone-like quality achieved through high-temperature kiln firing. Sometimes categorized under the radical for fire (火), its literal meaning can be interpreted as "fire-welded stone," linking it to traditional pottery and porcelain production. In modern usage, it appears in technical or historical contexts related to ceramics, distinguishing it from earthenware or other clay-based products by its density and non-porous finish after being fired at extremely high heat levels.
