Abstract
Low-temperature sintering porcelain bodies were obtained in Indiana feldspar-Nepheline syenite-Petalite-New Zealand kaolin system. However, the formability of this porcelain dough was low due to New Zealand kaolin which is inferior to other clay in plasticity. In this study, the effects of substitution Gairome clay and/or Kibushi clay for New Zealand kaolin on the sintering behavior and formability of this porcelain dough were investigated.
