Notes & Instructions

Glaze G2902B is a base crystalline formulation intended for high-expansion ceramic bodies to mitigate crazing. The recipe contains no clay or kaolin, resulting in a high-density slurry that requires the addition of an organic gum or flocculant to prevent rapid settling. Testing confirms the base is compatible with both raw and calcined zinc sources. While the formulation lacks colorants, it produces white crystals within a transparent matrix when fired according to the PLC6CR schedule. Performance and crystal morphology should be evaluated based on specific kiln firing profiles.
