Fake AshFiring temperature : Cone 6 | Surface texture : matte | Color : light yellow | Atmosphere: Reduction
This is a beautifully variegated fake ash glaze. It is a brighter yellow on porcelain with hints of green where thicker and terra cotta-colored where thin. It is not stable because it is low in silica, but to alter it would change the ash effect. While it does not meet strict requirements of stability, I use it anyway because I substituted strontium for barium.
