These glazes are modeled after traditional Guan or Snowflake glazes. They feature a delicate network of fine hairline cracks (known as crazing). While they are translucent, they become slightly opaque where the cracks form, creating a beautiful, multi-layered visual texture. Differences in glaze application and firing technique may affect your results. These glazes are technically food safe, but due to the crazed surface, do not use on areas that come in contact with food, (ie, rims of mugs, inside mugs, bowls, or plates).
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.
