FAQ All of my pieces are individually handmade on a potter's wheel. The pots are fired in a gas kiln at 1280°C (2336°F), producing either high-fired reduction or oxidation stoneware. All glazes are handmade from crushed igneous rocks and oxides in the studio and are microwave and dishwasher proof. The pieces are durable, chip-resistant and the glazes are resistant to food acids.
