| ABSTRACT |
|
The objective of the present research is to develop the body for Temmoku Teabowl, in order to manufacture the Temmoku Teabowl with the characteristics of Jian Ware, which has a rich dark brown color and has been extolled as the representative fine article of Temmoku Teabowl. Basic composition was first determined using domestically produced clay, kaolin and pottery stone as starting materials. After the addition of calcinated Hwangto, which is rich in iron, the mixture was subjected either to oxidizing calcination at $1260^{circ}C$ to produce a body with a color suitable for Hanam ware or to reducing calcination at $1230^{circ}C$ to produce a body with a color suitable for Jian Ware. The bodies produced in this research showed the strength value of $380{sim}36;Kg/cm^2$, the specific gravity of 2.304~2.310, the absorption ratio of 4.103~3.897, and the porosity of 8.608~8.207%. |
