Ash Celadon
For my ash celadon glaze, I collect high-silica volcanic ash rocks from a huge nearby deposition (the Upper Bandelier Tuff.) It is a soft enough that the Puebloan Indians used deer antlers to dig dwelling caves in its cliffs. After laborious processing and refinement, it becomes the best celadon glaze base I’ve encountered.
