GLAZE Russian patent published in 2008 - IPC C03C8/02 C04B41/86 

FIELD: chemistry.

SUBSTANCE: invention pertains to the technology of silicates, and specifically to the compounds of fritted glazes, which can be used for coating faced tiles and household ceramic products. The glaze consists of the following components with the give percentage mass ratios: SiO₂ 65.0-70.0; Al₂O₃ 1.0-2.0; Na₂O 1.0-2.0; K₂O 3.0-4.0; BaO 1.0-2.0; ZrO₂ 3.0-4.0; B₂O₃ 9.0-12.0; SrO 1.0-2.0; Sb₂O₃ 0.1-0.2; TiO₂ 0.8-1.8; MgO 5.0-8.0.

EFFECT: increased thermal stability of the glaze.
