Abstract

The invention relates to the technical field of pottery, and particularly relates to a wood-grain pottery glaze, and a process for preparing a pottery product by using the same. The wood-grain pottery glaze comprises the following components by weight: a bottom glaze comprising 43%-47% of potassium feldspar, 4%-6% of No. 1 clinker, 19%-21% of barium carbonate, 4%-6% of limestone, 4%-6% of calcined talcum, 9%-11% of Longyan kaolin, 9%-11% of titanium oxide and 1%-3% of vanadium yellow; a top glaze comprising 28%-32% of potassium feldspar, 39.9%-43.7% of No.2 clinker, 11%-13% of wollastonite, 5%-6% of Longyan kaolin, 10%-12% of pigments and 0.1%-0.3% of carboxymethyl cellulose. The process can overcome the problem that dissolution quantity of lead and cadmium exceeds a standard, reduces steps and labor cost, greatly increases yield of products, and saves production cost.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a wood-grain ceramic glaze and wood-grain ceramic products and techniques prepared therefrom. Background technique [0002] Ceramic products are widely used in our country, and the technology for preparing ceramics is also very mature. There is a layer of glaze on the outermost part of ceramics. One is to make the appearance of ceramic products more beautiful, and the other is to increase its tolerance. In order to make the appearance of ceramic products more exquisite, textures are generally supplemented on their outer surfaces. At present, there is no glaze that can express and maintain the wood grain texture of the green body. [0003] The wood grain effect produced by conventional technology has the disadvantages that lead and cadmium cannot be controlled, the process is cumbersome and complicated, there are many procedures, high labor cost, long production cycle, and dif...
