Ash Glaze

A glaze that employs organic (e.g. paper, wood) or volcanic ash as a source of oxides (e.g. silica, alumina, soda, calcia). Many books deal with the preparation of the organic ash batches (these materials are caustic) and provide example recipes. The chemistry of ash types and batches varies alot. The best approach is to accumulate a large batch, mix it, have an analysis done and use ceramic chemistry calculations to compare the chemistry of the ash with a target formula for the intended temperature. Then add the oxides the ash is lacking to make it into a glaze. In this way the maximum amount of ash can be employed in the recipe and the most variegation will be achieved. These is an example in the INSIGHT software manual (and a matching video at Digitalfire) on doing this.
