Description

This invention relates to a composition of blanked colored glazes used in ceramic tiles for glazing tiles,

The purpose of the invention is to reduce the frit cooking temperature, increase the gloss and obtain a blue coating.

The raw material used is quartz sand and boric acid, zinc oxide, copper, as well as waste from zirconium production. Donets-com chemical-metallurgical plant.

The glaze is prepared as follows.

The components are weighed, mixed thoroughly and melted at 1200 ° C, followed by granulation in water. Suspension is prepared from the obtained frit with the addition of 6% refractory clay and water to a moisture content of 45-47%

Wet grinding of the frit is carried out to a residue on sieve No. 0056 in the amount of 0.040-0.09%.
