SPECTRALUX OPACIFIERS

Our Spectralux Opacifiers were introduced in 1995. Since that time, customers in sanitaryware, tile, dinnerware, and core making have enjoyed the consistency of these products.

Continental Minerals Spectralux Opacifiers are processed to our exact specifications. Custom grinds are available to meet customer's specific requirements. Spectralux has proven through the years to offer superior opacification by quality manufacturers in sanitaryware, tile, insulator, dinnerware, procelain enamel and other whiteware industries.

Our precise particle size standards and chemistry also make Spectralux the preferred opacifier for ceramic core manufacturers.
