Glaze mass (I) for improving surfaces, comprises: silicon dioxide (30-55%); aluminum oxide (0-7%); metal oxide (a) (10-30%); bivalent metal oxide (b) (5-10%); boric oxide (0.5-15%); bismuth oxide (5-10%); phosphorus pentoxide (1-10%); antimony trioxide (0-5%); tin oxide (0-5%); titanium dioxide (0-5%); and zirconium oxide (5-10%), where the glass mass is obtained by melting together or sintering the components. Glaze mass (I) for improving surfaces, comprises: silicon dioxide (30-55%); aluminum oxide (0-7%); metal oxide of formula ((R) 2O) (a) (10-30%); bivalent metal oxide of formula (R 1O) (b) (5-10%); boric oxide (0.5-15%); bismuth oxide (5-10%); phosphorus pentoxide (1-10%); antimony trioxide (0-5%); tin oxide (0-5%); titanium dioxide (0-5%); and zirconium oxide (5-10%), where the glass mass is obtained by melting together or sintering the components. R : alkali metal; and R 1bivalent metal of alkaline earth metal or zinc. An independent claim is included for preparing (I), comprising mixing the components in fine granulate form as powder or paste, applying the powder or paste on a surface, heating the powder or paste, so that a reaction takes place between the components, combusting the paste on the surface designed for improving purpose at a combustible temperature, and obtaining (I) by cooling. |
