Abstract

The invention provides a jun porcelain jade glaze, which is prepared from the following raw materials in parts by weight: 52 to 58 parts of yellow feldspar, 19 to 25 parts of quartz, 13 to 19 parts ofcalcite, 1.5 to 2.5 parts of talc, 2.5 to 3.5 parts of zinc oxide, 0.5 to 1.5 parts of tin oxide and 0.25 to 0.75 part of copper oxide. Compared with the prior art, the jun porcelain jade glaze provided by the invention not only has a simple glaze formula, but also has the advantages of sufficient artistic conception, luster, red spots and strong jade texture through a scientific and reasonable ratio of the raw materials and a wood burning control process, the yield is up to 99% or more, and the shortcoming of low wood burning yield is overcome.

Description

technical field [0001] The invention relates to a glaze material, in particular to a Jun porcelain jade glaze and a preparation method thereof. Background technique [0002] Jun Porcelain is one of the five famous porcelains of the Song Dynasty in my country.
