GLASE COMPOSITION Russian patent published in 2011 - IPC C03C8/02 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of silicates and glase compositions for depositing on ceramic tiles and glased tiles. The glase composition contains the following, wt %: quartz sand 41.0-43.0; dolomite 10.0-12.0; borax 6.0-10.0; alumina 2.0-3.0; chalk 10.0-12.0; potash 5.0-6.0; zirconium dioxide 6.0-7.0; calcined soda 2.0-3.0; tin dioxide 10.0-12.0. From the said components, frit is boiled at temperature 1400-1470°C. The ready glase suspension is deposited on ceramic articles and burnt at temperature 950-1000°C for 30-45 minutes.

EFFECT: increased thermal stability of the glase.
