A ceramic product made by the glaze formula provided by the invention shows the cracking block effect on the glaze surface, and the cracking block effect is natural and vivid, and is rough and bold in cracks.

Description

A kind of glaze with cleavage block effect

Technical field

The present invention relates to a kind of glaze with cleavage block effect, belong to ceramic glaze technical field.

Background technology

Under modern civilization tide promotes, people are to the expectation of the aesthstic level of ceramic and pursue increasingly strong, and the ceramic of different decorative patterns makes ceramic effect field more colourful.At present, the ceramic with crazing effect on sale on the market, crackle is generally very thin, does not also have the ceramic of bulk cleavage block effect.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of glaze, for the preparation of the ceramic of bulk cleavage block effect.

In order to address the above problem, the invention provides a kind of glaze with cleavage block effect, comprise ground-coat enamel, middle glaze and cover-coat enamel, it is characterized in that, described ground-coat enamel comprises following raw material by weight percentage:

Described middle glaze comprises following raw material by weight percentage:

Described cover-coat enamel comprises following raw material by weight percentage

And pigment, the addition of pigment is to be no more than 7% of above-mentioned cover-coat enamel raw material gross weight.

The ceramic that adopts the formula of glaze provided by the invention to make, glaze surface can present a kind of effect of cleavage block, naturally true to nature, and crackle is rough bold and generous, crack width 1.5-2.5mm, the about 1.5--2.0/ square centimeter of cleavage block.
