The new Speedball Mid-Fire Glazes are an artist-led project developed in partnership with ceramic artist, Nancy Sowder, highlighting how artists shape Speedball’s development! This line consists of 30 glazes that create magical mottling and reduction like effects fired at Cone 5/6. Get eye-catching results when using each glaze on their own, or try layering colors for even more unique variation!


Available Colors

We have had an incredibly fun time formulating and testing these glazes to provide you with the most accurate performance data. However, results may vary based on individual application methods and firing techniques. We encourage you to create your own test pieces specific to your own practices to create a visual reference highlighting your unique process. We recommend a normal cooling cycle across all colors to ensure consistent results.
