Description

Gel-like glaze and preparation method thereof
Technical Field
The invention relates to the technical field of ceramic glaze, in particular to a gel-like glaze and a preparation method thereof.
Background
The celadon is known as the 'flower of porcelain' in that the porcelain has fine quality, bright and smooth lines, elegant and graceful shape and pure and gorgeous color. The celadon has the reputation of 'porcelain flower' with 'green like jade, bright like mirror and sound like chime', and is rich in variety and colorful in glaze color. The glaze is a colorless or colored vitreous thin layer covered on the surface of the ceramic product, and is prepared by mixing mineral raw materials and chemical raw materials according to a certain proportion, grinding to prepare glaze slip, applying the glaze slip on the surface of a blank body, and calcining at a certain temperature. It can increase the mechanical strength, thermal stability and dielectric strength of the product, and also has the characteristics of beautifying the ware, being convenient for wiping and washing, being not eroded by the fishy smell of dust, etc.
At present, the traditional Longquan celadon is generally a single-color glaze, and with the change of modern aesthetic concepts, the traditional ceramic glaze surface cannot provide a novel ceramic style, so that the ceramic decoration technology is limited in the traditional range. However, during the ancient dragon kiln firing process, grease-frozen glaze occasionally appeared due to the difference of materials and the change of firing temperature curve. But is limited by chance and cannot be the mainstream ceramic art to appear in the world. The ceramic device made of the congealing glaze fired by the formula utilizes the controllability of the modern process and the advantages of the texture such as transparent and thick enamel jade and the like. The artistic impact force of the ceramic works is effectively increased; is beneficial to the popularization and competitive power of the market.
