These Cone 5 Moroccan Texture glazes are formulated for mottled effects that vary based on the thickness of the glaze application. This glaze line comes in dry form so you will need to hydrate it. Moroccan Sand Satin Texture Glazes are best used right after mixing with water. Because of the formula composition, this line of glaze can jell within a day. Adding water to thin out the jelled glaze can lead to crawling. They are lead free and safe for use on food and beverage containers when properly fired. Test before use in production.
