noun
stoneware; high-fired pottery
Refers to a type of ceramic fired at high temperatures (around 1200–1300°C), resulting in a hard, non-porous body. Often used in technical or artistic contexts.
この急須は炻器でできているので、保温性が高い。
This teapot is made of stoneware, so it retains heat well.
炻器は陶器と磁器の中間の性質を持つ。
Stoneware has properties intermediate between earthenware and porcelain.
The kanji 炻 is a kokuji (Japanese-created character) combining 火 (fire) and 石 (stone), reflecting the stone-like hardness achieved through high-temperature firing. The reading せっき is the on'yomi of its components.
