Crystalline glazing is unlike any other surface treatment in ceramics. Instead of a predictable finish, it produces natural crystal blooms across the surface of a pot. No two pieces ever look the same, which makes every vase, bowl, or jar one-of-a-kind.
Crystalline glazing is a mix of precision and patience:
The glaze is formulated with zinc and silica to encourage crystal growth.
The firing reaches around 1300°C, melting the glaze into a glassy surface.
The cooling is carefully controlled, with the kiln held at exact temperatures to allow crystals to form.
The result is a glossy, glass-like surface scattered with delicate crystals — almost like flowers frozen in glass.
Because the process is so unpredictable, many ceramicists avoid it. It’s a high-risk, high-reward technique that requires:
Long firings and multiple temperature ramps
Specialised glaze chemistry
The willingness to lose pieces during experimentation
But when it succeeds, the effect is breathtaking.
In our Melbourne studio, crystalline glazing has become a passion project. Each piece takes weeks to plan, throw, fire, and finish. The results are porcelain vases and bowls that combine organic beauty with scientific precision — true collector’s items.
Crystalline pottery is best appreciated up close. The glossy crystals catch the light and shift as you move around them. Whether displayed as an art piece or used as a functional vase, each one becomes a conversation starter — a little bit of ceramic magic in your home.
