以下に抑えることができる。[Operation] According to the present invention, the conditions for good plasticity and good whiteness and light transmittance after firing are that the particles are fine, the shape is scaly or flat, and the shape is fibrous. By reducing the iron content to 2.6% or less in the composition and adding raw materials that do not contain titanium, organic glues such as CMC and PVA, and organic fibers such as sheet pulp, and adding water and kneading,
It does not use Frogme clay, Kibushi clay, kaolin, etc. used in the ceramics industry, and has good elasticity and smoothness during molding.
It provides a clay that does not stick to hands, is elastic, has fine workmanship, and can be bonded to other clays. After drying, it is elastic, strong, and defect-free, and when fired, It is possible to produce high-grade white ceramics with high whiteness and transparency. In addition, during firing, the volatile content of organic glue, organic fibers, etc. during firing is kept below the range of loss on ignition of ordinary ceramics, so it is possible to keep the burning tightness and shrinkage rate below the range of ordinary ceramics. can.

It has a composition of 4SiO2.H2O, and provides texture, lubricity, and non-viscous properties to clay. Sericite has a composition of K2O.3Al2O3.6SiO2, and sericite or sericite-containing chinastone powder imparts stretchability and toughness to clay.

Therefore, it is necessary that the content be 80 to 97% by weight.
