What is Crystalline Pottery?
Crystalline pottery is one of the rarest and most technically demanding forms of ceramic art — a discipline where chemistry, fire, and patience converge to grow real zinc silicate crystals inside the glaze. Unlike most pottery glazes, which dry to a uniform surface, crystalline glazes form macrocrystalline structures that can span several inches across a single piece.

Inside the Cone 8 Firing Process
Every crystalline piece I make goes through a precisely controlled Cone 8 firing — a 12 to 18 hour process where temperature is everything. The climb to peak heat melts the glaze into a liquid flux, and then the real work begins: a slow, deliberate descent through the crystal-growth window, held for hours at temperatures only a few degrees wide.

How Every Crystal Is Unique
No two crystalline pots have ever looked the same, and no two ever will. The crystals that grow inside my glazes form through a process governed by chemistry but shaped by chance — the same way snowflakes are identical in structure yet never in pattern.
