CO-3 is a dark, fluid glaze shifting between large crystals with blue and violet highlights at cone 5 and a bright gold surface at cone 6. Apply to: Cone 04 Bisqueware
Number of coats: 4 coats
This glaze performs best at cone 6 but can be fired to cone 5. For best results, leave the inside or back of the form unglazed.
Can be fired in a normal medium-speed firing with no special cooling schedule required. To take this glaze to the next level, use a controlled cooling schedule for increased crystal growth.
These glazes are prone to running so we recommend stopping your glaze about half an inch above the foot. You can also use a drip tray or soft bricks to protect kiln shelves.
Is this glaze food safe? Yes, but due to durability, these glazes are not recommended for food surfaces.
