Amaco CO-13 Mars Crystal, Pint

Mars Crystal is a highly fluid, dark brick red glaze with silvery, iridescent crystals. Opaque and breaks darker. 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.
