Embodiment Construction

[0016] Glaze is a colorless or colored glassy thin layer covering the surface of ceramic products. It is made of mineral raw materials (feldspar, quartz, talc, kaolin, etc.) and chemical raw materials in a certain proportion (some raw materials can be made into frits first) After being ground to make a glaze slurry, it is applied on the surface of the green body and calcined at a certain temperature. It can increase the mechanical strength, thermal stability and dielectric strength of the product, and it also has the characteristics of beautifying utensils, being easy to wipe and cleaning, and not being corroded by dust and filth.

[0017] An underglaze engraving and filling process of Jianshui purple pottery, which comprises the following steps:

[0018] (1) Mud making: Pound the selected pottery clay into powder, put it into a tank, add water to make a slurry, stir and wash it, take the above bleached slurry and pour it into another tank to let it dry naturally in a closed s...

Abstract

The invention particularly discloses an underglaze engraving and filling technology for purple pottery of Jianshui. The technology comprises steps as follows: clay production, throwing molding, painting and calligraphy decoration, engraving, filling and scraping, fine blank repairing, glazing, blank cooling and firing. After adoption of the technology, the technology has the advantages as follows: pottery produced with the technology reserves the traditional engraving and clay filling technology of the purple pottery of Jianshui and shows simplicity, variety and gentle nature of glaze, polishing is not required after firing, the yield can be increased, the labor force can be greatly reduced, the cost can be reduced, and underglaze engraving and filling has greater innovative value and significance for follow-up inheritance and development of the purple pottery of Jianshui.

Description

technical field [0001] The invention relates to the technical field of pottery production technology, in particular to an underglaze engraving and filling process of Jianshui purple pottery. Background technique [0002] Jianshui purple pottery is a traditional handicraft of the Han nationality with a long history. It is made of five-color clay in the suburbs of Jianshui. As bright as a rock, as bright as a mirror." [0003] In the prior art, Jianshui purple pottery must be polished after being fired. After polishing, the surface color of Jianshui purple pottery is relatively monotonous, and the requirements for the molding of pottery blanks are relatively high, so the yield of finished products is low, and Polishing can only be done manually, which is labor-intensive and costly. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the above technical defects and provide an underglaze engraving and filling process ...
