Compounded Body Clays

Clays for pottery body consisting of Pottery Stone, Kaolin, Kibushi Clay and Gairome Clay etc. Firing temperature of "1-S" & "NA-6" is both 1250~1300℃(centigrade).
Under oxidation firing condition, "NA-6" can get more white color.
Also "NA-6" is specially tough body clay and easy to produce bigger size products. "1-S" & "NA-6" both have good transparency.
