How it's made

Six steps, two firings, a few weeks of waiting.

A single bowl passes through the studio over two to three weeks. Most of that time the pot is simply drying — rushing any of it is how pots crack.

1 · Wedging

The clay is wedged by hand to drive out air pockets and line up the particles. Air left in the body will expand in the kiln and blow a hole in the wall of the pot.

2 · Throwing

Each piece is centred and pulled up on the wheel in the morning. A form like the rice bowl is thrown to the same weight of clay every time, so a set comes out even.

3 · Trimming

Once the pot is leather-hard, it goes back on the wheel upside down and the foot is trimmed — the step that gives a pot its lightness and its true base.

4 · Bisque firing

Bone-dry pots are fired slowly to around 900°C. This first firing hardens the clay enough to handle and glaze without it dissolving.

5 · Glazing

Pots are dipped in ash or celadon glaze mixed in the back room. The thickness of the dip, and where the glaze pools, decides how the fired colour reads.

6 · Glaze firing

The kiln is packed full and fired in reduction to around 1250°C over a day, then left to cool for another. Only when it's cold do we see what we actually made.
