Preparation method of purple ceramic

Abstract

The invention discloses a preparation method of purple porcelain. The preparation method is as follows: selecting yellow clay, red porcelain clay and stones; drying, crushing, adding a blender, adding water, preparing into slurry, mud milling, forming, and drying in the shade; carrying out shape modification, carrying out primary polishing and calendaring; drawing, engraving, carrying out secondary polishing and trimming; drying in the shade at low temperature, drying at intermediate temperate; drying, carrying out primary burning and secondary burning for carburization; and discharging from a kiln, carrying out polishing treatment and preparing into a finished product. In the invention, the raw material formula, the burning technology and temperature control are improved on the basis of the traditional technology for burning black pottery; the red porcelain clay is added into the raw material only containing single yellow clay; in order to increase the density, the crushed stones are added for supplement; and in order to increase the viscosity, proper amount of conditioner conforming to the standard is added. By utilizing the technology, in the link of the secondary burning for carburization, different kiln transmutations can be generated by controlling the temperature in the kiln, products with different colors are produced, the material for carburization is changed into lithospermum without toxicity and harm, and therefore, the produced purple porcelain has primitive simplicity, is natural, does not fade, is quietly elegant and noble and has very high value in art collection.

Description

technical field [0001] The invention relates to a method for preparing pottery. Background technique [0002] The patent number is: 2008101368956 The preparation method of black pottery, the yellow clay is crushed and then mixed with water to make a slurry, filtered, precipitated into strips, and then made into a green body of the required shape; the green body is dried in the shade, repaired, and polished once After painting, engraving, secondary polishing, and secondary drying in the shade, the body is surface-treated, and then put into the kiln for firing. When firing, smoked asphalt is added to make the smoke carbon produced by the asphalt covered in the kiln. fully absorbed by the body. In this method, asphalt is added in the carburizing process. The asphalt is radioactive and harmful to the human body after a long time.
