GLAZE COMPOSITION, METHOD FOR MANUFACTURING THE GLAZE COMPOSITION AND METHODS OF GLAZING

摘要

The invention provides a glass ceramic glaze composition manufactured using conventional raw material and one or more waste materials, wherein the waste materials are capable of producing glass forming oxides and glass modifying oxides. The waste materials are selected from a group that includes cullet, pozzolanic waste and fly ash. The invention also provides a method for manufacturing the glass ceramic glaze composition. Further, the invention provides different methods of glazing a glass ceramic substrate using the glass ceramic glaze composition.

主权项

1. A method for manufacturing a glass ceramic glaze composition, the method comprising:
grinding a set of raw materials into a powder, wherein the set of raw materials comprises white sand and at least one raw material selected from a group comprising pozzolanic waste, cullet, clay, lime stone, fly ash and commercial frits; drying the powder to obtain a dried powder; heating the dried powder at temperature of about 700° C. to about 900° C. to decompose the carbonates; heating the dried powder at a temperature of about 1300° C. to about 1400° C. to obtain molten glass; pouring the molten glass in water to obtain glass frits; drying the glass frits; grinding the glass fits into a fine powder; and sieving the fine powder to filter out particles having diameter more than about 90 microns.
