Thick white glaze ceramics and preparation method thereof

Abstract

The invention belongs to the technical field of domestic ceramics, and particularly relates to thick white glaze ceramics and a preparation method thereof. The thick white glaze ceramics comprise thefollowing materials: crystal frit, potassium feldspar, Longyan kaolin, zinc oxide, Guangfeng calcined talc, strontium carbonate and titanium dioxide. The process method is adopted, through the fact that raw material selecting, formulation optimizing and preparation technique controlling are conducted, a glaze of the prepared ceramic glaze is thick, glossiness is high, and the thickness can reach 2-3mm. Under oxidation flame, the burned glaze is white and yellowish with lard white colors, the glaze is crystal clear with oil but not greasy, and particularly noble, glaze materials are applied tohigh white green bodies, the effect is especially obvious, the ratio of fishing products is high, and the glaze materials are suitable for promotion and application of the domestic ceramics and display ceramics.

Description

technical field [0001] The invention belongs to the field of glaze preparation, and in particular relates to a fertile white glaze ceramic and a preparation method thereof. Background technique [0002] Dehua, together with Jingdezhen and Liling, is known as the "Three Ancient Porcelain Capitals of China". Since the Song Dynasty, Dehua white porcelain has become an important export product of the "Maritime Silk Road" and has been sought after by European nobles. In the Ming Dynasty, porcelain masters produced a kind of warm milky white porcelain that was as fat as jade. The French praised Dehua white porcelain as "BLANC DE CHINE" at that time, and they thought it was "Chinese porcelain". top grade". Dehua white porcelain is well-known at home and abroad for its unique porcelain quality and craftsmanship. It has the reputation of "the world's white porcelain looks at China, and the Chinese white porcelain looks at Dehua". Therefore, it has become a business card of China fac...

Problems solved by technology

In order to maximize the decorative effect of the high-white glaze, ceramic workers try to thicken the glaze layer, but the glaze tends to flow down after melting at high temperature and flow to the setter, causing the ceramic to stick to the bottom; reduce the firing temperature Although the thickness of the glaze layer can be guaranteed, the green body is difficult to sinter, the strength is reduced, and the permeability of the green body is reduced. At the same time, the glaze surface is also prone to defects such as raw burning, orange glaze, and unevenness.
