Crystalline Ceramics

Crystalline glazed porcelain forms by Richard Bideau

Crystalline Glaze

Careful control of chemistry and firing conditions give rise to glazes that produce crystals during the firing cycle. Crystals are stunning with fantastic shapes that shimmer like holograms as light catches them. The possibilities are almost endless…

About Me

I have been exploring the crystalline process since 1997, becoming a full-time potter in 2009. My former career in chemical engineering, coupled with a lifelong association with pottery have given me the skills needed to combine art and science.
