Embodiment 1
[0015] Crackle glaze is made of the following raw materials according to mass percentage: 10% albite feldspar, 11% kaolin, 1% quartz, 7% zinc oxide, 8% barium carbonate, and 63% frit;
[0016] Described frit is made up of following raw material by mass percentage: quartz 8%, red lead 45%, feldspar 10%, dolomite 12%, barium carbonate 25%, wherein feldspar is made of potassium feldspar and albite by 2~ 3:1 mass ratio composition.
[0017] The production process of crackle glaze, the specific production steps are as follows:
[0018] (1) Preparation of frit: separately pulverize quartz, red lead, potassium feldspar, albite, dolomite and barium carbonate, and mix them uniformly in proportion to smelt to prepare frit;
[0019] (2) Preparation of glaze: crush each raw material and frit separately, mix them uniformly in proportion to obtain a mixture, then add water according to the mass ratio of mixture:water 1:0.6, stir for 3 hours, ball mill for 7 hours, pass 400 ~600-mesh sieve...
