Decreasing pinhole defect formation probability on cobalt feldspar glazes for porcelain production

Pegmatite from the Chupin deposit with mica impurities which is used for the production of glaze for porcelain can be responsible for the formation of pinhole defects. It has been established that adding calcinated kaolin to cobalt feldspar glaze decreases the formation probability of this defect.
