Problems solved by technology

The traditional kiln-changing glaze is fired at medium and high temperature, the firing temperature is above 1200°C, and the firing time is mostly more than 12 hours. The high firing temperature, long time, and large energy loss lead to high cost and are not environmentally friendly; There are light-weight Baiyun pottery kiln-changing glazes with a single glaze effect and monotonous varieties, which cannot meet the needs of consumers with different personalities

specific Embodiment 1

[0024] The glaze formula is as follows in parts by weight: 40 parts of glass powder, 30 parts of transparent frit glaze, 10 parts of red material, 5 parts of nepheline powder, 5 parts of boric acid, 8 parts of kaolin, and 2 parts of zinc oxide.

[0025] The preparation method of the above-mentioned light-weight porcelain low-temperature kiln erythema glaze comprises the following steps:

[0026] Step 1: Put glass powder, transparent frit glaze, nepheline powder, boric acid, kaolin, and zinc oxide into a ball mill jar, and add 60% water;

[0027] Step 2, after ball milling for 12 hours, put the red material into the ball mill jar and mill together for 30 minutes;

[0028] In step 3, the glaze obtained in step 2 is passed through a 200-mesh sieve for use, so as to obtain the kiln erythema glaze.

[0029] The method of using the low-temperature kiln erythema glaze for light porcelain comprises the following steps:

[0030] Step 1, preparing a lightweight ceramic green body;

Abstract

The invention belongs to the field of manufacturing of ceramics, and particularly relates to a furnace transmutation glaze formula for light porcelain firing, a preparation method and a using method. The light porcelain low-temperature furnace transmutation red spot glaze formula comprises glass powder, transparent fritted glaze, red ceramic pigment, nepheline syenite, boronic acid, kaolin and zinc oxide. The furnace transmutation red spot glaze formula is low in cost, convenient to use and low in firing temperature, and has unique art sense. The ground color of a glaze surface fired by furnace transmutation red spot glaze is red or copper red, irregular black spots are distributed on the ground color of the glaze surface uniformly, sizes and densities of the black spots are respectively changed according to ceramic shapes and glazing thicknesses, and an artistic effect is unique. Grades and sale prices of porcelains manufactured by the glaze are increased, and economic value is high. In addition, the glaze can be industrially produced in batches, can be popularized quickly, is easy to use, and has high competitiveness in markets.

Description

technical field [0001] The invention belongs to the field of ceramic manufacturing, and in particular relates to a kiln-transformed glaze formula, preparation method and application method for firing light-weight porcelain. Background technique [0002] Kiln-changing glaze means that when the utensils are fired in the kiln, due to the oxidation or reduction of various color elements in the kiln, they will show unexpected glaze color effects after they come out of the kiln. The traditional kiln-changing glaze is fired at medium and high temperature, the firing temperature is above 1200°C, and the firing time is mostly more than 12 hours. The high firing temperature, long time, and large energy consumption lead to high cost and are not environmentally friendly; There are light-weight Baiyun pottery kiln-changing glazes with a single glaze effect and monotonous varieties, which cannot cater to the needs of consumers with different personalities. [0003] In order to solve the ...
