Mayco Pottery Cascade™ are commonly used by low-fire designers who seek to simulate effects of higher fire glazes. With the disappearance of leaded glazes from the markets, Cascades have been used to create the flowing movement lead used to provide. Pottery Cascade™ glazes were designed to mature at a shelf cone 06 (999° C). Make sure the glaze has dried thoroughly prior to firing. A medium ramp/firing rate is recommended (250°F per hour).
