Cone 6 oxidation (larger image): Smoke is an opaque grey-blue stoneware glaze with soft, subtle variegating hues. Application thickness strongly influences the fired color; surface texture will also produce variegation during the firing.
Cone 10 reduction (smaller image): Color changes to a variegated sage green with a glossy finish.
TIP: One coat creates a blue-grey haze over a weathered brown; Two coats intensify the grey cast while Three coats intensify the overall grey-blue opaque finish. Brown breaks on raised surfaces on the body.
