Abstract

The invention provides a high-transmittance eggshell white ceramic product. The high-transmittance eggshell white ceramic product comprises a preform body and glaze, wherein the preform body is prepared from the following raw materials in parts by weight: 45 to 50 parts of kaolin, 18 to 25 parts of potassium feldspar, 15 to 18 parts of montmorillonite, 10 to 15 parts of quartz, 10 to 14 parts of clay and 1 to 5 parts of talc; the glaze is prepared from the following raw materials in parts by weight: 25 to 30 parts of nepheline syenite, 18 to 22 parts of dolomite, 8 to 12 parts of burned talc,4 to 8 parts of kaolin, 3 to 6 parts of calcium carbonate, 3 to 5 parts of sepiolite, 2 to 5 parts of plant ash, 0 to 3 parts of potassium oxide, 0 to 2 parts of sodium oxide and 0.1 to 0.5 part of ferric oxide. The making method provided by the invention comprises the steps of burdening, throwing, fettling, biscuit firing, glazing and firing. The ceramic product prepared from the raw materials bythe process has the characteristics of white glazing color, high transmittance, clear and clean glaze surface, firm and white matrix, warm jade color, no cracks on the whole, and certain water resistance and thermal stability.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a white ceramic product with high light transmission and thin body and a manufacturing method thereof. Background technique [0002] Thin-bodied porcelain began in the Northern Song Dynasty and has a history of thousands of years. It is famous all over the world for its thin body. There are many poems describing thin-bodied porcelain, "thin as cicada's wings", "I'm afraid the wind will blow it away, and it will be sold in the sun", "pure glaze, almost no fetal bone", "moisturizing and transparent, thin and light", these are all It describes the characteristics of thin bodied porcelain as thin as paper, white as jade, bright as mirror, and sound like fragrance. More than 4,000 years ago, the black pottery of the Longshan culture was produced at a very high level, with an extremely thin wall of 0.5-1mm, known as the thin and bright eggshell black pottery.
