Spectrum’s 1104 Grass Green cone 4/6 stoneware glaze is a glossy opaque glaze. It creates a unique effect of green breaking into yellow. It is a favorite among school kids!! This glaze will bring out a bright color on white stoneware, while producing a more rustic effect 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.
