Cobblestones create a textured cobbled surface when fired. Apply over another glaze and during the firing process, a shattered pattern of raised, irregular chips will emerge. Cobblestones have been formulated to mature at cone 06/05. However can be fired to higher temperatures to add a unique look. Their performance at cone 6 is noted on each individual product label. We recommend testing on your clay body and in your kiln prior to use.

APPLICATION: Shake for 5-6 seconds before use. Dispense glaze onto a palette (tile, plate, etc.) and apply 2 coats with a broad, soft brush, such as a CB-604 #4 Soft Fan Brush. Apply the second coat while the first coat is still damp: do not allow Cobblestone to dry between coats. Pattern break-up is determined by the application direction of the brush stroke. Large break up heavier application, small breakup lighter application. If application is too light the cobblestone will not break up. Reapplying and touching up will not achieve a break up. Fire to shelf cone 06 or higher.

Cobblestone glazes are have been certified as Non-Toxic, safe for use by artists of all ages when used according to manufacturer’s directions. However, they are not recommended for dinnerware due to the durability of the fired glaze. Some glazes, regardless of surface texture or porosity of underlying clay body, will be designated as not suitable for dinnerware as the fired glaze surface is not durable and can be impacted by contact with food or liquids. While it may not be harmful, it is certainly not desirable. Further, these glazes 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.
