In the sagger, must have the following conditions
1, there is considerable intensity;
The high temperature of 2, capable of considerable;
3, at high temperature, not shrink, or narrowing of little;
4, in the high temperature in no load softening, or refractoriness under load is small;
5, can contend with temperature at;
6, thermal conductivity. With blank (namely blank into sagger), first sprinkle a thin layer of rice husk ash in the saggerbottom, or high alumina clay, or quartz powder to dike billet and the sagger melting. At the same time ordinary alsosettled slag cake blank, especially the flow of color glaze blank larger to stick son, then put the soft cake, so as not to burn into glaze into the sagger in on finished products.
