Spectrum’s 1149 Oceanic Blue cone 4/6 stoneware glaze is a glossy, blue glaze. This is a favorite among school age children! It produces a smooth and even surface, and is brighter on white clay than on darker clay bodies. All of Spectrum’s 1100 Stoneware Glazes are available in wet formats and are suitable for brush application.
Spectrum’s 1100 glazes comprise a series of cone 4/6 stoneware glazes that are both lead-free and dinnerware safe. Most of them also come with the A/P non-toxic rating from the Art & Creative Materials Institute (ACMI) marked on the product label. Some of the reactive type glazes are rated C/L by the ACMI which means that they are toxic in the liquid (unfired) state due to the presence of heavy metals, such as copper or vanadium, beyond the non-toxic legal limit. C/L rated glazes should not be handled by young children or pregnant women.
Try overlapping glazes for new and interesting glaze results. Some of Spectrum Glazes are designed to move and shift in the glaze firing resulting in beautifully bright and layered looks.
