Ceramic and enamel glazes
borax increase ceramics’ (such as tiles, tableware, ceramics and enamel device, etc.) compressive strength, abrasion resistance and chemical resistance. As the thermal expansion coefficient of B2O3 on the control of making the glaze to adapt the line to improve, but also can reduce the melting temperature of B2O3, prevent loss through. Makes the product more smooth and more perfect.
