Technical field
The present invention relates to a kind of coffee-like crystallization enamel composition, belong to construction sanitary ceramic decoration technique field.
Background technology
Crystalline glaze refers to occur in glaze substantially thick macrocrystalline glaze.It is a kind of ornamental very strong artistic glaze, comes from me
The coloured glaze in state's ancient times.The basic feature that crystalline glaze is different from common glaze is in glaze to contain a number of visible crystalline solid
(the crystalline substance flower on the glaze that i.e. we can see or in glaze).
The crystalline substance of crystalline glaze spends changeable, the amount doesn't matter, and big is visible to the naked eye, and small need to be differentiated with microscope.Crystalline glaze
Porcelain can also rationally to control the distribution of brilliant flower by artificial method.Shape has star, needle-like or floral leaf shape etc..As
A kind of advanced ceramic artistic glaze, beautiful, the novel natural brilliant flower of crystalline glaze, and its outward appearance are varied, color in riotous profusion, give
People is deep to be welcome by users at home and abroad with strong artistic effect.
Crystalline glaze is very popular due to its pure color.The crystallization soaking time of traditional crystalline glaze usually requires 4
~6 hours, high cost limited its application in building ceramics.Current Ceramic Tiles industry is generally fast using low temperature
