Solar Rainbow glaze is a highly fluid, dark gloss glaze with iridescent rainbow crystals. Breaks translucent.

Apply to: Cone 04 Bisqueware
Number of coats: 4 coats
Glaze fire to cone 5/6

This cosmo 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 cosmos 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.

Safety Warning

Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
