Improvement of the raw glaze quality using colemanite

A comprehensive study of the boron-containing component, colemanite, has been carried out. Glaze coatings have been synthesized with its application. The optimal content of colemanite in the composition of the charge composition is 3--6%, which makes it possible to expand the glaze formation interval by reducing the temperature of the appearance of the glassy phase from 1150 to 1000 ° C. While maintaining the required level of physical and chemical properties, the synthesized coatings are distinguished by high values ??of aesthetic indicators: gloss - 87%, whiteness - 89%.
