Cone 6 oxidation (larger image): Micro Ash is a glossy, translucent, variegated charcoal glaze with a periwinkle float that breaks over texture. Blooms of shimmering onyx micro-crystallization will develop during the firing process.   Cone 10 reduction (smaller image): Glaze darkens. TIP: This glaze is fluid at 3 coats. Recede application to avoid unwanted runoff. Due to the translucent nature of this product, be aware of your application consistency and thickness to avoid streaky brushstrokes. We recommend firing our micro glazes to cone 6 oxidation to reach crystalline development. Micro Ash achieves a stable, semi-opaque, warm charcoal result that breaks over texture and has a pearlescent satin finish when fired to cone 5. Can be used in oxidation or reduction firings. Results may vary. The choice of clay body, thickness of application, firing process, and temperature will greatly affect the fired results. Always test your application on your clay body in your kiln environment.
