Using Earthenware Glazes

Minnesota Clay Earthenware Glazes are leadless and available in powder and liquid form. Mix powdered glaze with tap water at a ratio of 12 fluid ounces per pound of glaze. Using a blender will help to activate the suspending agents in the mixture and the resulting slurry should be poured through a 60 mesh sieve. The resulting mixture will likely need an addition of water to obtain a slightly thicker than whole milk consistency. If you have a hydrometer, a 1.40 -1.45 reading is a good target. Premixed Liquid Glazes should be shaken well and poured into a glaze bucket through a 60 mesh screen. Add water if necessary to achieve a slightly thicker than whole milk consistency.
