Problems solved by technology

[0003] Existing glazes mostly use transparent materials. Even in-glaze products show the primary colors of red and green in the transparent glazes, and do not change special natural colors through the kiln. At present, the high-grade porcelain handicrafts on the market have little effect on glazes. The requirements are very high, and the invention provides a kind of emerald green glaze and its firing method

Abstract

The invention provides a jade green glaze material and a firing method thereof. Ferrous iron is added into a traditional glaze material formula, nitrogen gas is introduced stage by stage in the firing process for protection, it is ensured that the jade color of the glaze material is beautiful, and meanwhile binding of the glaze material and a semifinished product cannot be affected; attapulgite is added, a layer chain structure of the attapulgite is adopted as a template, compounds prepared in the firing process are arranged in order, the reflected color has no variedness, and the color uniformity is quite high; europium oxide is added, the fluorescence property of the europium oxide is utilized, the glossiness of a porcelain glaze material is improved, and the jade-like gleaming sense on the surface of porcelain is improved.

Description

technical field [0001] The invention relates to the field of ceramic glazes, in particular to an emerald green glaze and a firing method thereof. Background technique [0002] The ceramic industry attaches great importance to the adoption of advanced glaze technology. There have been a large number of highly professional ceramic glazes and ceramic frits and pigment companies in China. The glazes used in ceramic products are becoming more and more diverse. At present, most ceramic enterprises use The types and uses of glaze products can be roughly classified as follows: 1. Lead glaze and lead-free glaze; 2. Raw glaze and frit glaze; 3. Glaze for primary firing or secondary firing; 4. Ceramic tiles, tableware , glazes for sanitary ceramics and electric porcelain; 5. Dip glazes, spray glazes, pouring glazes according to glazing methods; 6. High-temperature glazes and low-temperature glazes; 7. High-expansion glazes and low-expansion glazes; 8. Firing atmosphere oxidation flames...
