Problems solved by technology

The main types of Jianzhan are Rabbit Haozhan and Oil Dropping Cup. The current reported methods for preparing Jianzhan have the following limitations: First, the firing of Jianzhan is difficult, and the firing process is difficult to master. Improper process selection often leads to many problems. Defects, such as blistering, deformation, body cracking, glaze sticking to the bottom, large number of glaze pinholes and other defects, low yield, etc., thus reducing the artistic, collection and economic value of Jianzhan; second, Jianzhan Glazed designs and colors are ordinary, with low innovation

Embodiment 1

[0037] The described method of reverse reduction firing to build a lamp comprises the following steps:

[0038] (1) preparation of green body and glaze slurry, wherein,

[0039] The green body is prepared by the following method: the clay is obtained by mixing 9 parts by weight of laterite and 1 part by weight of kaolin; ; Drawing the billet mud into a billet, repairing billet, bisque burning, cooling to obtain billet;

[0040] The glaze slurry is prepared by the following method: take 350 parts by weight of glaze stone, 250 parts by weight of limestone, 1500 parts by weight of plant ash, 50 parts by weight of iron red and 2200 parts by weight of water, add it in a ball mill and grind, pass 120 Mesh sieve to obtain glaze slurry;

[0041] The preparation method of the plant ash is as follows: burning oak wood to obtain ashes, and grinding the ashes into powder.

[0042] Further, the laterite and kaolin are all taken from Shuiji Town, Jianyang District, Nanping City, Fujian P...

Embodiment 2 and Embodiment 3

[0054] Jianzhan is very sensitive to the preparation process parameters. Small changes in process parameters will have a great adverse effect on the appearance and other characteristics of the final product of Jianzhan, and even lead to the failure of the preparation of Jianzhan. Therefore, Jianzhan has very strict requirements on the preparation process. . Example 2 and Example 3 were prepared according to the same preparation process as Example 1, and the properties of the fixture prepared in Example 2 and Example 3 were basically the same as those prepared in Example 1. The results showed that Example 1 The method has good repeatability, strong stability, and is easy for large-scale production.

Abstract

The invention discloses a method for reverse reduction firing of a Jianzhan cup, which comprises the following steps: preparing a green body and glaze slip, not glazing the outer bottom of the green body during glazing, and glazing other parts. And putting the glazed and air-dried green body into an electric kiln for roasting. The Jianzhan glaze stripes obtained by firing are mainly irregular rippled stripes like cloud and running water, are mixed with dotted stripes and millifilaments like stars, and are rich in charm. The colors are silver blue, yellowish brown and earthy yellow in sequence from bottom to top and are gradually transited, the layering sense is high, and excellent artistic and collection values are achieved.

Description

technical field [0001] The present invention relates to the technical field of porcelain, in particular to a preparation process of a jar. Background technique [0002] Jianzhan is produced in Jianyang and is a famous traditional porcelain. The main types of Jianzhan are rabbit hair cups and oil drop cups. The currently reported method for preparing Jianzhang has the following limitations: First, the burning of Jianzhang is difficult, the burning process is difficult to master, and improper process selection often leads to many problems. Defects, such as blistering, deformation, body cracking, glaze sticking to the bottom, many glaze pinholes and other defects, low yield, etc., thus reducing the artistic, collection and economic value of Jianzhan; second, Jianzhan The glazed designs are common and less innovative. [0003] Therefore, there is a need in the art to develop a manufacturing process for building lamps with beautiful and novel appearance and stable process. SU...
