Spectrum Glazes

Spectrum's formulations have been developed over their 20 years in business with careful attention to detail, backed by an on-going commitment to thorough testing of materials and every batch of finished product. All Spectrum products use ceramic frits and stains as their principal ingredients. This provides superior appearance and consistency of results over other products made primarily from raw materials, such as minerals and metal oxides. Spectrum glazes also use a higher percentage of stains in their formulae which gives greater intensity, brightness, and depth of color to glazes, underglazes, etc.
