• Due to variations in raw materials used during manufacturing, we recommend firing glazed test tiles before using each new batch number of glaze.
• Applying Kiln Ice glazes thicker than traditional AMACO glazes is critical to achieving nice crackle patterns. Multiple brushed layers is better than one thick layer.
• Before the ware is fired, handle with care so glaze does not flake off the edges. Incorporate a drip ring on convex forms for the glaze to gather near the bottom of the piece. Additionally, leaving a larger unglazed area on the piece helps gasses escape the body and minimize pin-holing.
• Glaze the interior & exterior of the ware. Having some glaze on the interior and exterior of the piece is recommended but it doesn't necessarily have to be a full body wrap.
• Allow your fired piece to sit for a day or two for the full snowflake crackle effect to take place. Delayed crazing is common with this glaze; allowing the piece to cool for several days will enhance the crackle effect and add more depth to your fired piece.
