First, I'm a subscriber to the Glaze Recipes. Is it possible to search by color? It would save me a lot of time and aggravation. Can someone explain the order of the glaze recipes? Another question is color variety. For instance orange, a favorite color. Are there oranges that cannot be used straight out of the jar, or using varying amounts of underglaze? Also, has anyone successfully added underglazes to gloss or matte clear? Thanks!
