Cone 6 oxidation (larger image): Olive Float is a dark green gloss glaze that contains a light green crystal. It is a dazzling glaze that mimics crystalline glazes without the fuss of complicated kiln programing!
Cone 10 reduction (smaller image): Color changes to red. Crystals remain.
TIP: SW-210 Emerald is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-210 Emerald with a third coat of SW-151 Olive Float.
