Low-Fire Glaze Recipes

A Rainbow of Glazes from Lower Temperature to Higher

You can make a full rainbow of pottery glazes for your projects. Low-fire temperatures allow the use of colorants that would burn off or become unstable at higher temperatures. These 15 low-fire glaze recipes are arranged from ​a lower temperature to higher, with the firing range given in cones. The percentages given in these recipes are by weight, not by volume. Your glaze batches should be mixed using distilled water. Whenever you are trying out a new glaze, make small batches and test them.
