Abstract

The invention discloses transparent glaze and a manufacture technology thereof. The transparent glaze is composed of potash feldspar, Longyan kaolin, quartz, zinc oxide and barium carbonate at a certain mass ratio. The manufacture technology comprises the following steps: uniformly mixing the above raw materials, adding water, fully stirring, ball-milling, sieving through a sieve, coating the surface of a sintered porcelain body with transparent glaze, sending the porcelain body into a heating-up furnace and carrying out three stagewise high-temperature firings, taking the product out of the furnace, and cooling. The formula of the transparent glaze is reasonable. The manufactured transparent glaze has stable glaze effect, presents a crystal and clear glaze effect, is flawless, has uniform and fine texture, has good quality and is beautiful and elegant.

Description
