Karst was made using a cardboard mould that was subsequently burned away and the finished piece looks as though it might have been hewn from the living rock. Its two apertures reveal the interior of the piece – which is white – to draw light in.

The title of this piece refers to the iron-rich bands of clay that run through this rugged, upright, vessel, creating rusty-looking stripes. It’s part of the Terra-form collection, inspired by coal mining and the notion of manipulating an alien landscape.

As with much of Fuller’s oeuvre, this was made using a cardboard mould and has a rock-like sense of heft. A pair of apertures mean that it’s possible to see straight through the piece, and the interior has a polished finish, inspired by artist Barbara Hepworth.

Sub-Terra’s striking colour was caused by red iron oxide in the clay body, which was subsequently fired at around 1220°C. The large cracks on the inside of the vessel were created by the maker hitting the piece with an over-sized hammer.

The title, Tafone, refers to cavities that develop in a rock face. To create a rougher, almost striated, finish, the artist used a thicker grade of cardboard (that he found in IKEA) to create his mould. The piece has two apertures and a highly polished interior.
