Description
Summary: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 metallisation. 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 that 13% dextrin should be introduced into cobalt-bearing paints. 1 ref.
