Problems solved by technology

[0003] At present, the main types of Jianzhan are Rabbit and Oil Droppers, and the degree of innovation in glazed designs and colors is relatively low.
In addition, during the firing process of Jianzhan, firing is very difficult, and it is often difficult to control the formula, firing atmosphere and temperature curve, and the following defects often occur: body cracks, glaze sticking to the bottom, air bubbles, and glaze jumping. The glaze and crystal patterns are not displayed or clear, the patterns are dim, etc., and the yield is very low (generally 20-50%)

Embodiment 1

[0039] The firing process of colored gold oil drop building lamp includes the following steps:

[0040] (1) Green body preparation: get 3 parts by weight of red clay and 7 parts by weight of kaolin, mix them, add water to wash them, and pass through a 100-mesh sieve to obtain mud; Drawing and molding, drying, trimming and bisque firing to obtain the green body;

[0041] The biscuit firing is that the furnace temperature is raised to 800° C. after 6 hours, and then the furnace is stopped for cooling.

[0042] (2) Grinding the glaze ore with water, passing through an 80-mesh sieve, settling, drying for subsequent use;

[0043] The plant ash is washed, passed through a 80-mesh sieve, precipitated, and dried for later use; the preparation method of the plant ash is as follows: 1.2 parts by weight of moso bamboo and 16 parts by weight of pomelo tree are mixed and burned to obtain ashes.

[0044] (3) Preparation of the main glaze slurry: Take 43 parts by weight of glaze ore, 20 pa...

Embodiment 2

[0056] The firing process of colored gold oil drop building lamp includes the following steps:

[0057] (1) Body preparation: get 2 parts by weight of red clay and 8 parts by weight of kaolin and mix them, add water to wash, and pass through a 100-mesh sieve to obtain mud; Drawing and molding, drying, trimming and bisque firing to obtain the green body;

[0058] For the biscuit firing, the furnace temperature was raised to 800° C. after 5.5 hours, and then the furnace was stopped for cooling.

[0059] (2) Grinding the glaze ore with water, passing through a 90-mesh sieve, settling, drying for subsequent use;

[0060] The plant ash is washed, passed through a 90-mesh sieve, precipitated, and dried for later use; the preparation method of the plant ash is as follows: 1.5 parts by weight of moso bamboo and 15 parts by weight of pomelo tree are mixed and burned to obtain ashes.

[0061] (3) Preparation of the main body glaze slurry: Take 40 parts by weight of glaze ore, 18 parts...

Embodiment 3

[0074] The firing process of colored gold oil drop building lamp includes the following steps:

[0075] (1) Body preparation: get 3 parts by weight of laterite and 7 parts by weight of kaolin, mix them, add water to wash, and pass through a 110-mesh sieve to obtain mud; Drawing and molding, drying, trimming and bisque firing to obtain the green body;

[0076] The biscuit firing is that the furnace temperature is raised to 800° C. after 5 hours, and the furnace is stopped for cooling.

[0077] (2) Grinding the glaze ore with water, passing through an 80-mesh sieve, settling, drying for subsequent use;

[0078] The plant ash is washed, passed through a 80-mesh sieve, precipitated, and dried for later use; the preparation method of the plant ash is as follows: take 1 weight part of moso bamboo and 18 parts by weight of pomelo tree and burn them together to obtain ashes.

[0079] (3) Preparation of the main glaze slurry: Take 45 parts by weight of glaze ore, 19 parts by weight o...

Abstract

The invention discloses a colored gold oil drop cup building and firing process. The process comprises the following steps: preparing a green body, main body glaze slip and mouth edge glaze slip, applying the mouth edge glaze slip to the mouth edge of the green body, carrying out pre-sintering, applying the main body glaze slip to the pre-sintered green body, putting the glazed and air-dried greenbody into an electric kiln, and implementing roasting, cooling and discharging. The fired colored gold oil drop built cup has the advantages that oil drop stripes and hair are generated on the glazesurface, the oil drop stripes and hair are generated at the same time, the single type of traditional oil drops and rabbit hair is broken through, different stripe effects are shown, and meanwhile, part of oil drops are in a semi-crystalline state (partially transparent) and have the beauty of glittering and glittering. The glaze surface is of a color mainly comprising purple gold and silver blue,and the color saturation is high.

Description

technical field [0001] The invention relates to the technical field of porcelain, in particular to a firing process for building a bowl made of colored gold and oil droplets. Background technique [0002] Black-glazed porcelain is a strange flower in the history of Chinese ceramics, well-known at home and abroad. Jianzhan is a typical representative of black-glazed porcelain. The colorful light phenomenon of Jianzhan is natural, mysterious and refined, and the markings of Jianzhan have obvious three-dimensional and layered feelings. What Jianzhan pursues is the artistic effect formed naturally. Its glaze color pattern is not artificially painted, but formed under strict formula technology, firing temperature curve and special firing atmosphere. The three are indispensable. The artistic effect formed by Jianzhan has no sense of artificial carving at all, and it is completely a display of the essential beauty of its products. [0003] At present, the main types of Jianzhan a...
