Problems solved by technology

However, due to the low-temperature glaze firing, the strength of the glaze surface is low, and it is not easy to maintain. You can only clean it with your hands, not with a dishwasher or a cleaning ball, so as not to scratch the glaze surface and form dirt.
Using a microwave oven for too many times of heat exchange will damage the porcelain, make the glaze of the porcelain black, and cannot resist acid, etc.

Embodiment 1

[0024] 1). The green glaze is composed of the following components in weight percentage: 40-55% of bone meal, 25-34% of kaolin, 8-12% of clay, 8-14% of feldspar or quartz, and the rest are electrolyte additives. The total percentage is 100%. The purpose is to increase the firing temperature.

[0025] 2) After the billet is formed, it is burnt at 800°C and then polished smoothly, then glazed, and then the mouth and bottom glazes are removed;

[0026] 3). When loading the blank, put the edge of the product with the edge glaze removed upside down in the groove of the shaped cushion cake, and load the blank into the kiln together. The first firing of the blank and the glaze is made in a reducing atmosphere. The forming temperature is 1350°C, and the shaped cushion cake is a groove cushion cake that is made of the same mud material used in the product and is completely consistent with the edge of the product;

[0027] 4). After firing, after cooling, choose the porcelain and grade, past...

Embodiment 2

[0028] Example 2: The glaze material is the same as above

[0029] 1) After the blank is formed, it is sintered at 780°C and then polished smoothly, then glazed, and then the mouth and bottom glazes are removed;

[0030] 2). When loading the blank, put the edge of the product with the edge glaze removed upside down in the groove of the shaped cushion cake, and load the blank into the kiln together. The first firing of the blank and glaze is made by reducing flame once. The forming temperature is 1330°C, and the shaped cushion cake is a groove cushion cake that is made of the same mud material used in the product and is completely consistent with the edge of the product;

[0031] 3). After firing, after cooling, choose the porcelain and grade, paste the colored flowers in the glaze, wait for the decals to dry, and then glaze the mouth, and then fire it in a weak reducing atmosphere at 1270℃ for the second time. The in-glaze color is fired at the same time as the glaze is fired.

Embodiment 3

[0032] Example 3: The glaze material is the same as above

[0033] 1) After the blank is formed, it is sintered at 800℃ and then polished smoothly, then glazed, and then the mouth and bottom glazes are removed;

[0034] 2). When loading the blank, put the edge of the product with the edge glaze removed upside down in the groove of the shaped cushion cake, and load the blank into the kiln together. The first firing of the blank and glaze is made by reducing flame once. The forming temperature is 1350°C, and the shaped cushion cake is a groove cushion cake that is made of the same mud material used in the product and is completely consistent with the edge of the product;

[0035] 3). After firing, after cooling, choose the porcelain and grade, paste the colored flowers in the glaze, wait for the decals to dry, and then glaze the mouth, and then fire the second time in a weak reducing atmosphere at 1280℃, that is, the second mouth The in-glaze color is fired at the same time as the gla...

Abstract

The invention belongs to the technical field of firing ceramics, in particular to a firing process for strengthening enamel bone china. Its characteristics are: after the blank is formed, it is polished smooth after biscuit firing at 780-800°C, then glazed, and then the glaze on the edge and bottom edge is removed; when loading the blank, the edge of the product with the glaze removed In the groove of the shaped pad cake, put the billets into the kiln together, and use the reduction flame for the first firing, and the firing temperature is 1330-1350°C. The shaped pad cake is made of the same mud as the product. A groove pad cake made of mud that completely matches the edge of the finished product; after firing and cooling, the porcelain is selected and graded, and the colored flowers in the glaze are pasted. Secondary firing in a weak reducing atmosphere, that is, firing the in-glaze color at the same time as the second mouth glaze firing. The strengthened enamel bone china of the invention has the characteristics of good whiteness, good translucency, good heat stability, high glaze hardness, no lead cadmium dissolution and the like.

Description

Technical field [0001] The invention belongs to the technical field of ceramic firing, and particularly relates to a firing process of reinforced enamel bone china. Background technique [0002] Bone china is usually a kind of porcelain that is fired twice at high temperature and low temperature glaze firing. The porcelain is delicate and transparent, the glazed surface is moist and bright, and the furnishings are elegant. However, due to the low-temperature glaze firing, the glaze has low strength and is not easy to maintain. It can only be cleaned by hand, and can not be cleaned with a dishwasher or cleaning ball to avoid the formation of dirt after the glaze is scratched. Using the microwave oven for more heat exchanges will damage the porcelain, make the porcelain glaze black, and cannot resist acid. For example, the application number is 200610102103.4, and the invention name is the method disclosed in "Colored Bone China and Its Production Method". After grouting or machi...
