Problems solved by technology

Due to the high altitude (above 1000m), windy sand, little rain, large temperature difference between day and night, and harsh weather conditions in the western region, it is more difficult to develop high-grade art porcelain.

Embodiment 1

[0028] Embodiment 1, a kind of firing method of art ceramics, concrete steps are as follows:

[0029] (1) Raw material ingredients

[0030] a. Material preparation: pick out the stones, iron and other impurities mixed with raw materials, according to the proportion of raw materials: white sand 15%, feldspar 5%, burnt gem 6%, kaolin 50%, sub-wood knot 20%, talc 4%, accurately weigh various required raw materials, the chemical composition of each raw material is shown in Table (1), put into the wet ball mill, ball stone: raw material: water=1.6~2.0: 1: 0.4~0.45;

[0031] b. Grinding: Determine the grinding time and slurry fineness according to the fineness required by the formula, generally 16-20 hours / grinding, the slurry fineness is 100 mesh sieve, and the slurry specific gravity is 1.6-1.7;

[0032] (2) Forming: Gypsum mold is used for grouting molding, and the grouting time is determined according to the size of the green body for 45 to 90 minutes, and the thickness of the ...

Abstract

The invention relates to a method for firing art ceramic products, which comprises the process steps of (1) raw material dosing, (2) forming, (3) bonding and trimming, (4) biscuit firing, (5) glazing, (6) glaze firing, and (7) drawing. The method adopts secondary firing process and reducing flame and fully utilizes local row materials and parts of industrial chemical row material ingredients (including ferrum, copper, tin, copper, titanium and the like) to perform firing at reducing atmosphere. The ferrum, the copper and other ingredients are reacted jointly to change product pigment, therebyforming top-grade artistic ceramics which are gorgeous in color, gentle in hue, natural in glaze flow and simple in texture. The method adopts cheap raw materials, low manufacture cost and reasonableprocess, product pass rate can reach more than 90%, and mass production can be achieved.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a method for firing artistic ceramic products in high-altitude areas. Background technique [0002] Traditional ceramic production generally adopts one-time firing process, which is characterized by simple process, less process, low cost, but low product yield, single tone, monotonous color, and poor artistic effect. With the progress of society and the change of people's aesthetics, the requirements for the artistry and appreciation of ceramics are also getting higher and higher. Ceramic art changes with the times and innovates with the market. From the perspective of peers, Jiangnan and the Central Plains region, taking advantage of the favorable natural conditions of low altitude (below 500m), less wind and sand, small temperature difference between day and night, and mild climate, adopts the secondary firing process ( Reduction flame firing), firing out rich in color, smooth in color...
