Firing Temperature: Δ6
Surface Type: Glossy

Notes: Alisa Clausen: A very fluid, gloss glaze with colours throughout varying from greenish brown to opal blues and whites. A lot of
movement in the glaze and one big pinhole where thickest under lip. Streaking on inside of bowl led to a pool of aqua gloss in middle
of bowl. Bulging edge of glaze on foot, almost a drip. Goes more opal white where thickest.
