Improvement of the technology for obtaining pigment-free brightly colored glazes

A new method of coloring glazes is proposed on the basis of improvements in the technology for obtaining brightly colored glass coatings. The method consists of a complex of physical-chemical processes (adsorption, ion-exchange, and precipitation) which already occur at the stage of preparation of the glaze slips, containing water-soluble salts of variable-valence metals, which imparts intense and uniform color and high-quality to calcined glass coatings. __________ Translated from Steklo i Keramika, No. 3, pp. 21–22, March, 2007.
