Transparent Frits

Transparent Frit-product code started with HT, FT- are suitable for high-quality transparent glossy glazes for single-fired and double-fired floor tiles and wall tiles. They can be mixed with other Transparent Frits to get glazes with desired coefficient of thermal expansion (C.O.E) and surface. Also, they can be mixed with Opaque Frits to get high-quality semi-opaque glazes. Besides, they can be used as transparent powder printing.
