Amaco (CO) Cosmos Glazes

Amaco’s (CO) Cosmos glazes are mid-to-high-fire (Cone 5–6) crystalline glazes that evoke the mysterious beauty of distant galaxies with their iridescent swirls and shimmering flecks. Designed to fire beautifully in standard kiln schedules, Cosmos glazes require no special cooling to produce celestial surfaces, though controlled cooling can enhance crystallization. While technically food safe, their delicate surface is best reserved for decorative pieces rather than everyday functional ware
