What you only learn by firing it.

Our studio practice: we throw ceramics, test mineral blends and take clay bodies and glazes through vitrification.

Thrown and hand-built forms that show how a clay body behaves in daily use: strength, weight, wear.

Local earths and minerals mixed, fired and compared for strength, color and safety, so the finishes we recommend are tested, not assumed.

Taking clay bodies and glazes to the point where they turn dense, durable and non-porous, and logging every firing.

Firing logs, blend tests and notes from the kiln, published here as the work happens.

What we learn about durable, non-toxic, earth-based surfaces feeds straight into the tiles, plasters and finishes we recommend for clients.
