CO-21 Galactic Glacier is a highly fluid light blue glaze with iridescent crystals that flash pink, violet, and silver.

Apply to: Cone 04 Bisqueware
Number of coats: 4 coats

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.

Due to variations in raw materials used during manufacturing, we recommend firing glazed test tiles before using each new batch number of glaze.

Cone 6 = 1241°C (at 150°C/hour for the final 100°C of firing)

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.
