Celadon Firing Technology Combining Ge Glaze and Di Glaze

Abstract

The invention relates to the field of celadon ware arts and crafts and particularly discloses a traditional dragon spring elder brother glaze and younger brother glaze combined calcining process and glaze formulas. The expansion coefficient difference of an elder brother glaze and a younger brother glaze is relatively large, the cracking limiting temperature of the elder brother glaze is higher than the highest limiting temperature for calcining the younger brother glaze, and the flowability of the younger brother glaze becomes high when the elder brother glaze reaches the cracking limiting temperature, so that the traditional celadon artworks almost have no condition that the elder brother glaze and the younger brother glaze are combined to be calcined, and particularly, artworks with different glazes at the inside and outside, such as a vessel with the inside made of the elder brother glaze and the outside made of the younger brother glaze or a vessel with the inside made of the younger brother glaze and the outside made of the elder brother glaze, are not tried by an artist. Through changing the glaze formulas of the elder brother glaze and the younger brother glaze, the lowest limiting temperature for hacking the elder brother glaze is lowered, the highest limiting temperature for calcining the younger brother glaze is raised, an overlapping region exists between the temperature for calcining the elder brother glaze and the temperature for calcining the younger brother glaze, the hacking of the elder brother glaze is ensured, meanwhile, the flowability of the younger brother glaze is relatively stable, and the basis is laid for the combined calcining of the elder brother glaze and the younger brother glaze.

Description

technical field [0001] The invention relates to the field of celadon arts and crafts, in particular to a process method for combining and firing traditional Longquan Ge glaze and Di glaze. Background technique [0002] Longquan celadon began in the Jin Dynasty, began to take shape in the Northern Song Dynasty, and entered its heyday during the Song and Yuan Dynasties. The scale of porcelain making was unprecedented, and the craftsmanship reached its peak. center of the porcelain industry. There are two kinds of Longquan celadon products: one is white body and cinnabar body celadon, known as "Dr. Kiln" or "Longquan Kiln", and the other is black body celadon with split glaze, called "Ge Kiln". [0003] The glaze layer of brother kiln celadon is rich, the glaze color is green and green, the luster is soft, crystal clear and moist, it is better than emerald. There are different glaze colors such as plum green, pink green, moon white, bean green glaze, light blue, and gray yell...

Problems solved by technology

[0006] Due to the large difference in expansion coefficient between Ge glaze and Di glaze, the cracking limit temperature of Ge glaze is higher than the maximum limit temperature of firing Di glaze. It is rare for celadon handicrafts to be fired in combination with elder glaze and younger glaze, especially for crafts with different glazes inside and outside, such as inner glaze and outer glaze, or inner glaze and outer glaze, which have different glazes. master try
