I handthrow my pots on my pottery wheel using white and dark stoneware clays. The glazes that I use look a bit different on each one of the clays - more 'earthy' and speckled on darker stoneware, more 'clean' and crisp on white stoneware.
Once dry, the pots are bisque-fired to about 1000 C. They are then glazed and fired again to 1280-1300 C. During this second firing, the clay 'matures' with the glaze, melding together inseparably. This makes for very strong pots - the glaze will not chip off from the clay - you'd have to break the whole pot to see where they fuse! This durability allows the pots to be put in the microwave, dishwasher and oven.
I have an electric kiln and a gas-fired kiln. Using the same glazes, the outcomes look very different depending on the kiln and firing process (oxidation or reduction).
If you don't see something that you like, I am very happy to do a custom order for something a bit more personal. Do get in touch!
