Experiences in ceramics

Ash
glazes

From plant ash to ceramic surfaces: an experience that began with an interest in traditional glazing techniques and took shape in the studio through material preparation, composition tests and firing results.

In the studio

From leaves
to surface

Dry palm leaves would fall in the studio garden. I collected them and burned them slowly to obtain the ash I would use in my glazes. After experimenting with different compositions, I found a mixture of albite and ash that worked in my gas kiln at cone 6. The results also varied with the application: dipping or spraying revealed different colours and textures on the surfaces.
