Problems solved by technology

The surface of the Jianzhan fired by the dragon kiln firewood method is smooth, the pattern is beautiful, the pores are few, but the design and color cannot be controlled, and the yield is very low (generally no more than 30%)
[0006] At present, there is no firing method that is easy to control, and at the same time has a warm glaze and beautiful colors.

Embodiment 1

[0045] The firing process of the described Jianzhan comprises the following steps:

[0046] (1) preparing green body and glaze slurry;

[0047] The green body is prepared by the following method: mixing 5 parts by weight of yellow mud, 3 parts by weight of kaolin, and 6 parts by weight of red clay, crushing, elutriating, passing through an 80-mesh sieve, filtering the mud, and then refining the mud. Old, after aging, mud is smelted to obtain green body raw materials, and the green body raw materials are drawn into shape, trimmed, biscuit, and cooled to obtain the green body;

[0048] In the step (1) biscuit firing is that the temperature of the kiln rises from normal temperature to 800° C. at a constant speed within 6 hours, then the furnace is stopped and cooled.

[0049] The glaze slurry is prepared by the following method: elutriating plant ash, stirring, passing through a 100-mesh sieve, standing for 12 hours to separate layers, discarding the water, and obtaining a preci...

Abstract

The invention discloses a firing process of a Jianzhan cup. The firing process comprises the following steps: preparing a green body and glaze slip; and performing glazing by adopting internal oscillation and external immersion methods, not glazing the outer bottom of the green body, and putting the glazed and air-dried green body into a natural gas kiln to be roasted, wherein the natural gas kiln is provided with a burner for introducing natural gas for combustion. The natural gas kiln is adopted for firing the Jianzhan, a good reducing atmosphere is provided, the glaze color of the fired Jianzhan is mild and is close to the quality of firewood-fired Jianzhan, but the yield is far higher than that of firewood-fired Jianzhan; the fired Jianzhan cup has the advantages that the glaze surface is black and bright, the vitrification effect is good, the mouth edge is golden and moist, meanwhile, oil drop crystal spots are uniformly distributed on the glaze surface, the oil drop crystal spots are clear, glittering and translucent, and the Jianzhan cup has extremely high ornamental value and artistic value.

Description

technical field [0001] The invention relates to the technical field of porcelain, in particular to the firing process of Jianzhan. Background technique [0002] Jianzhan is one of the eight famous porcelains in my country. Jian kiln is a famous kiln in my country, and its kiln has become a rare top grade. In the family of Jianzhan, decorations such as oil drops, rabbit hairs, and partridge spots are treasures of Jianzhan, which makes people love it. [0003] At present, Jianzhan mainly adopts two methods of electric firing and dragon kiln firewood firing. Each method has its own advantages and disadvantages: [0004] Electric firing is to convert electric energy into heat energy to raise the temperature in the kiln. When the kiln reaches a certain temperature, add a certain amount of oil firewood to make the kiln generate a reducing atmosphere suitable for firing. Its cost is low, and the color is more stable and easy to burn. control, but there are many pores, the degree...
