It is also known as fritted glaze and patterned glaze. The glaze of porcelain is covered with many small cracks, ranging from sparse to dense, from thick to thin, from long to short, from curved to straight, which look like cracking, crab claw or ice crack patterns, called crack sleeves. There are two preparation methods: ① cover a layer of color glaze of high expansion system on the sleeve layer of the product, and repeat baking. When cooling, the outer glaze cracks due to inconsistent shrinkage, and the cracks show the color of the bottom glaze, that is, sandwich crackle glaze; ② A layer of glaze with expansion coefficient greater than that of the body is directly applied to the body, and glaze cracks are directly generated by the tensile stress generated by the glaze, and then the cracks are dyed by dipping the product with metal solution or ink, so as to obtain a glaze full of color texture network, that is, mosaic crackle glaze. glaze crack was originally a defect in porcelain making process, but it was used to decorate porcelain. Ge Kiln is famous for this characteristic. The pattern is interlaced into many fine eye shapes, known as roe pattern; Those with dense and relatively fine patterns are called hundred garbage fragments. Mainly used for decoration of art ceramics and building ceramics.
