There are loads of possibilities for great surfaces in the low fire temperature range, from textured to matt, or majolica to glossy transparent glazes. Today, I am posting a sample recipe from this collection—a dry lithium glaze with a great texture.  - Jennifer Poellot Harnetty, editor

* Caution should be exercised when working with and around ceramic raw materials. Wear a respirator when working with the dry materials, make sure your kiln is well ventilated, and that your workspace is separate from your kiln area.

These dry lithium glazes are applied to earthenware and fired up to cone 04. To retain application texture and dry surface quality, fire only to cone 010. Multiple firings may be necessary for color intensity and depth. Shivering may occur if the glaze firing is prolonged. The recommended firing schedule is to turn up the kiln (electric) one third every two hours, so that the kiln is on high in four hours.
