Abstract
It is established that dextrin contained in cobalt-bearing paints influences the quality of decorative ceramics. The content of dextrin is responsible for the probability of such defects as paint crumbling and cobalt metallization. As the content of dextrin in a paint grows and its adhesive capacity increases, the glaze layer thickness at the sites of paint application decreases, as well as the viscosity, the wetting angle, and the porosity of glaze. It is recommended to introduce 13% dextrin into cobalt-bearing paints.
