1. Before use must be made via high temperature calcination, calcination temperature at about 1200 ℃. If not calcine directly add to the raw glaze, will influence the glaze process performance. You do not need to calcine in join frit material.
2. The dosage of zinc oxide in the glaze overshoot affects glaze gloss.
3. The zinc oxide have poor effects on certain glaze, especially chromium glaze. Part in foshan ceramic enterprises through long-term study found that zinc oxide can also has effects in reducing the bibulous rate of floor tile of wall of pottery and porcelain. The personage inside course of study thinks, in the ceramic glaze formula about the fineness of 1000 items of zinc oxide powder, due to the small particle size, specific surface increases, the lower the water absorption. Of course the higher mesh, the higher the price of zinc oxide.
