Abstract

The invention relates to nark glaze, a bark glaze ceramic product prepared from the bark glaze and a preparation method of the bark glaze ceramic product, which belong to the technical field of ceramics. The bark glaze comprises the following raw materials in parts by weight: 35-37 parts of potash feldspar, 18-21 parts of barium carbonate, 14-17 parts of dolomite, 9-12 parts of calcium carbonate, 16-18 parts of bone ash and 4-5 parts of a chromogenic reagent, wherein the chromogenic reagent is a mixture of ferric oxide and manganese oxide at a mass ratio of 3:2. The preparation method comprises the following steps: according to the formula, mixing the raw materials and ball-milling; mixing to obtain glaze slip with required concentration; glazing and sintering, so as to obtain the bark glaze ceramic product. In the invention, through the reasonable formula and the simple preparation method, the bark glaze ceramic product returns to nature, is attractive in glaze and is environment-friendly, and energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a bark glaze, a bark glaze ceramic product prepared by using the same and a preparation method. Background technique [0002] Ceramic vessels, fired from clay, have many deficiencies that glazing can make up for and add charm to the piece. Glazing can weaken the penetration of the vessel and overcome the defects of air permeability and water permeability of the blank itself; the fired ceramic vessel after glazing is easy to clean, dry and remove dust; the glaze covers the surface of the blank to make up for the lack of a single color of the clay itself. [0003] However, brightly colored glazes on the market account for the majority. Although the ceramic products made are bright and beautiful, they lack natural flavor. Just like staying in the noisy city for a long time, people yearn for the simple and unpretentious country life instead. So consider researching a k...
