Cone 6: Night Moth is a opaque gloss glaze with crystals that bloom into a sage and gray. Heavier crystal application will produce more colour variation.
Cone 10: No change.
TIP: SW-508 Black Gloss is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-508 Black Gloss with a third coat of SW-181 Night Moth.
