Ulla makes slab-built sculptural ceramics, the majority of which are a playful take on classical container forms, in particular the bottle. These pieces, especially when displayed in groups, have an animated almost human air about them.
Although Ulla works from templates slight variations in assembly make each piece unique.
After bisque firing most pieces are glazed and then raku fired in a kiln that Ulla has built in her garden. Others are coated with a crackle slip and fired in an electric kiln, a process which produces a matt surface and a more subtle crackle pattern brought out by brushing the surface with an ink solution. Both firing techniques give unpredictable results which adds to the uniqueness of each final piece.
