Cone 6 oxidation (larger image): Celadon Bloom is a turquoise semi-transparent gloss glaze that contains a white crystal.

Cone 10 reduction (smaller image): Color lightens. Crystals remain.

TIP: SW-201 Turquoise is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-201 Turquoise with a third coat of SW-150 Celadon Bloom.
