Cone 6: 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: 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.
I put Smoke glaze on a couple different clay coloured pieces to test how it breaks on texture and when mixed. Happy with the results so far.
