Copper red glaze with patterns like marks left by earthworms crawling on mud and preparation method thereof

Abstract

The invention discloses copper red glaze with patterns like marks left by earthworms crawling on mud. The copper red glaze is prepared from the following raw materials in parts by weight: 50-70 partsof yellow feldspar, 12-18 parts of calcite, 8-12 parts of quartz, 4-6 parts of copper ore, 5-7 parts of Suzhou kaolin, 2-4 parts of black hairy soil, 0.5-1.5 parts of talc, 0.3-0.7 part of cupric oxide, 6-10 parts of azorite, and 6-10 parts of wollastonite. The preparation method of the copper red glaze with the patterns like marks left by earthworms crawling on mud comprises the following steps:(1) pulverizing the above raw materials, then mixing and ball milling, adding water till the mass concentration of the glaze reaches 55-56%, wet grinding for 8-10 hours, allowing the slurry treated bythe wet grinding to pass through a 120-300 mesh sieve to obtain glaze slurry; (2) immersing blank bodies in the glaze for 2-3 times; and (3) firing, wherein the firing temperature is 1280-1320 DEG C.The lines on the fired glaze layer are smooth, round, natural, soft in tone and beautiful, and are like the marks left by earthworms crawling on mud, and the yield is 70% or more.

Description

technical field [0001] The invention relates to the technical field of Jun porcelain manufacture, in particular to a copper red glaze with earthworm slime texture and a preparation method thereof. Background technique [0002] Jun porcelain originated in the Eastern Han Dynasty. It is one of the five famous kiln porcelains in the Song Dynasty. It is a treasure in the traditional Chinese porcelain making process. " and "a family with ten thousand crowns is not as good as a piece of Jun porcelain".
