Apply Kiln Ice glazes thicker than traditional Amaco glazes, at least 1/8 in. thick (3.175mm). 3-4 heavy coats are recommended. Thickness is critical to achieve crackle.
Application Tips: Apply Kiln Ice glazes thicker than traditional Amaco glazes, at least an 1/8 inch thick (3.175mm). Glaze thickness is critical to achieve a nice crackle. Multiple brushed on layers is better than one thick one. When the glaze thickness starts to get heavy it will take longer to dry in between coats, this is due to the gums that are added to make it brushable also slows the dry time when glaze is thick.
TIPS & TRICKS
Applying Kiln Ice glazes thicker than traditional AMACOglazes 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 notflake off the edges.
Incorporate a drip ring (see image below) on convex formsfor the glaze to gather near the bottom of the piece. Additionally, it leaves a larger unglazed areaon the piece that helps gasses escape the body and minimizes pin-holing.
Glaze the interior & exterior of the ware. Having someglaze on the interior and exterior of the piece is recommended but it doesn'tnecessarily have to be a full body wrap. Leaving some exposed clay, as statedpreviously, will help gasses escape the clay body to minimize pin-holing.
Allow your fired piece to sit for a day or two for the full snowflakecrackle 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 yourfired piece.
Food Safe? Yes, but due to durability, these glazes are not recommended for food surfaces. Use a liner glaze for any food surfaces on functional wares.
