What are Mayco Micro Glazes?
"Micro" is short for "microcrystalline" which is a glaze that develops small crystallization from the the zinc and silica during the cooling process. Micros do not actually contain a glass crystal like our other stoneware crystal glazes. Rather, the effect is created by the glaze itself during the firing process. These glazes can be fired from cones 5-10, but the crystallization may not form at higher temperatures. The micros are not dinnerware safe due to surface durability, with the exception of the Micro Pearl. We recommend using micros on the outside of dinnerware, below the lip line or on decorative wares.

Cone 6 oxidation (larger image): Micro Cerulean is a glossy, translucent, medium blue glaze with an aqua float that breaks over texture. Blooms of shimmering blue micro-crystallization will develop during the firing process.  

Cone 10 reduction (smaller image): Glaze turns to a variegated grey/blue. 

TIP: This glaze is stable at 3 coats. Additional coats or increased application thickness may result in movement. 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 Cerulean achieves a stable, semi-opaque, deep blue 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.
