Hawksbill color spot transmutation glaze porcelain and preparation method thereof

Abstract

The invention discloses hawksbill color spot transmutation glaze porcelain and a preparation method thereof. The hawksbill color spot transmutation glaze porcelain comprises hawksbill color spot transmutation glaze arranged on a ceramic green body, and the hawksbill color spot transmutation glaze comprises, by weight, 25-35 parts of feldspar, 10-15 parts of limestone, 10-15 parts of dolomite and 18-25 parts of quartz; 3-6 parts of bentonite, 5-8 parts of rutile, 5-10 parts of zinc oxide, 5-8 parts of ferric oxide and 1-3 parts of lithium carbonate. According to the invention, by changing the components and proportion of the glaze, the fired porcelain glaze has semi-matte gloss, hawksbill color spots, partial yellow color, partial brown color, partial grey black color, crystalline-like flow lines and antique color, and is elegant and charm; the transmutation glaze is prepared by firing in an oxidizing atmosphere at a medium temperature of 1220-1250 DEG C, so that the firing temperature is reduced, the cost is reduced, the product percent of pass is also improved, and the furnace transmutation glaze has certain environmental protection and economic values.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a kiln-changing glaze porcelain with tortoiseshell color spots and a preparation method thereof. Background technique [0002] "Kiln change" - as the name suggests, refers to the name of the phenomenon that the glaze color deviates from its original color during the firing process. It should specifically refer to the abnormal change of the glaze color endowed by the thermal history of the firing process. "Barnyard History Compilation" contains: "Enamel is of the same quality, so it becomes a different quality, and the same color, then becomes a different color. The combination of water and soil cannot be added by human coincidence, which is called kiln transformation." Modern research shows that the kiln change has both chemical color components and physical color effects. Although the mechanism of kiln transformation cannot be fully grasped, one or all of the follo...

Problems solved by technology

[0004] At present, most of the Jingdezhen kiln glaze and Henan Yuzhou Jun porcelain glaze on the market are fired at high temperature (usually 1300-1320°C) in a reducing atmosphere. When firing in a reducing atmosphere, there are required The temperature is high, and the qualification rate of the products fired at the same time is not ideal, etc.
