Classic Crackles© are glazes that are designed to “craze”; that is, develop subtle surface cracks in the finished glaze. Developed for Cone 06 but can be fired up to Cone 6 with some change (refer to side of jar).
Shake well. We recommend a broad, soft brush, such as a CB-604 #4 Soft Fan Brush, to apply the glaze. Apply three coats to properly fired shelf cone 04 bisque. Fire to shelf cone 06. After firing, wipe an acrylic or ink over the ware and wipe off, allowing the ink to fill and highlight the cracks.
Classic Crackles© glazes have been certified as AP Non-Toxic, safe for use by artists of all ages when used according to manufacturer’s directions. However, they are not recommended for dinnerware as these glazes can exhibit surface textures such as cracks and crevices. While the glazed surface may pass lead & cadmium leach tests, and therefore legally considered Food Safe, attempts to adequately clean the textured surface may cause the underlying porous ware to absorb water and fail. Recommended for ornamental use only.
