Erosion Cup – small


A hand made Erosion cup (or yunomi) with iron matt glaze interior.  The textured surface is left unglazed and takes on colour and markings during its firing in a charcoal filled saggar box within the wood kiln (also known as tanka firing). The beautiful interior glaze developed fine crystals within its surface as the iron oxide changed form during the firing. The lack of oxygen within the saggars causes this to happen. Sometimes, over time and with use, metallic iron on the glaze surface will re-oxidise and tiny bright rust spots appear. These are perfectly safe and can be wiped away with a cloth, or appreciated as a sign of the continuation of change.

Perfect as a whisky sipper or shot cup for a small dram. Stoneware. approx 140ml
