Dock 6 Pottery is wheel-thrown, high-fired stoneware. The pots are fired to about 2400 degrees in a natural gas kiln so pieces without fused glass can be used in the oven, microwave, and dishwasher. Pots with fused glass are primarily decorative but can be used with dry foods and should be hand-washed. All pots are durable and they will not lose their vibrant colors over time. See more.
