The new Speedball Mid-Fire Glazes are an artist-led project developed in partnership with ceramic artist, Nancy Sowder, highlighting how artists shape Speedballs 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 colours for even more unique variation! Size: 473ml (16oz).
