Embodiment 1

[0042]A kind of azure glaze for Ru porcelain made of black stone, made from the following raw materials: Dengfeng feldspar, Ruzhou feldspar, calcite, agate powder, black stone, ashes, and chestnut wood ash. The weight percentage of each raw material is: 38% of Dengfeng feldspar, 28% of Ruzhou feldspar, 5% of calcite, 6% of agate powder, 20% of black stone, 2% of ashes, and 1% of chestnut wood ash.

[0043] The preparation method of the chestnut wood ash is: first put the wood ash into a large basin, pour into clear water, soak for 3 hours, then stir to make it fully diluted, pass through a 50-mesh sieve to remove unburned firewood and impurities, and then pass through the 80-mesh sieve again. Filter through a mesh sieve, and after filtering, precipitate for 6 hours, then pour off the water, leaving solid matter, and obtain it after natural drying.

[0044] The preparation method of the agate powder is as follows: first calcining the natural agate, the firing temperature is 120...

Abstract

The invention relates to a Ru porcelain sky-blue glaze with black stone as a raw material. The Ru porcelain sky-blue glaze is prepared from the following raw materials in percentage by weight: Dengfeng feldspar, Ruzhou feldspar, calcite, agate, black stone, bone ash and chestnut ash. The Ru porcelain sky-blue glaze prepared by the formula and the firing method of the invention has the chromaticitybasically consistent with that of a traditional Ru porcelain sky-blue glaze sample, and is stable in firing effect and low in defective rate. Meanwhile, the black stone is low in raw material cost, the manufacturing cost can be greatly reduced, and the black stone has good commercial value and strong popularization.

Description

technical field [0001] The invention belongs to the technical field of ceramic glazes, and in particular relates to a Ru porcelain sky blue glaze using black stone as a raw material, a preparation method and a firing process thereof.
