Problems solved by technology

[0004] In the prior art, the method of multi-layer glazing is adopted for the metallic luster glaze. The process is as follows: apply the base glaze on the surface of the porcelain body, then apply the color base with metallic luster on the surface of the base glaze, and finally apply the top glaze and fire to make porcelain. The process is complicated, and the production efficiency is difficult to improve. In addition, the artificially drawn color base texture is unnatural, the metal texture is not strong, and the artistic value is not high

[0038] Raw material preparation:

[0039] Albite feldspar 2.8kg, choose colorless and white albite;

[0040] Quartz 2.2kg, the quartz is low-temperature quartz, colorless and milky white;

[0041] Zircon 1kg, the choice of zircon is yellow and red;

[0042] Potassium feldspar 300g, the choice of potassium feldspar is flesh red;

[0043] Glass beads 800g;

[0044] The preparation steps are as follows:

[0045] Step J01: Take all raw materials other than glass microspheres and put them into a pulverizer to grind them until all the powders pass through a sieve with an aperture of 2mm. Use a mixer to mix the powders evenly again to obtain batch materials, and add the batch materials to the sintering process. In the furnace, heat up to 1380°C and keep it fired for 30 minutes, then add glass beads, use a ceramic stirring head to heat and mix for 15 minut...

Abstract

The invention relates to transmutation glaze with metallic luster and transmutation glaze porcelain, and belongs to the technical field of ceramics. The transmutation glaze comprises the following components in parts by weight: 82-90 parts of high-transparency basic glaze and 8.5-12 parts of color forming glaze. According to the color forming glaze, kenamite and spodumene are used as main color generating raw materials, and a ground color layer which is natural in texture and has a rusted metal color is formed after firing. Yttrium oxide and antimony oxide form a solid solution in a crystal phase during high-temperature firing, and grain growth is hindered. Further, refined crystal grains are formed, so that higher reflectivity is achieved. The product has strong metal texture, and the high-transparency basic glaze adopts albite, quartz, zirconite, potassium feldspar and glass beads as raw materials, and has the characteristics of high transparency and high brightness after being fired at high temperature; in addition, in combination with the metal texture provided by the color developing agent, the ceramic is endowed with metallic luster.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a kiln-changing glaze with metallic luster and kiln-changing glaze porcelain. Background technique [0002] Kiln-change glaze is a kind of glaze whose glaze color deviates from its original color during the firing process. The formation of kiln change has both chemical mechanism and physical effect. Although the mechanism of kiln change cannot be fully grasped, it can be achieved through the setting of formula and process parameters. Make the kiln change to the direction of design. [0003] Metal luster glaze is a new type of ceramic art glaze. It has elegant, luxurious and solemn artistic effects. The architectural ceramic products decorated with it have realistic metal decoration effects. Therefore, ceramic products with metallic luster are more and more popular in consumption. favored by those. [0004] In the prior art, the method of multi-layer glazing is adop...
