How it is made All ceramics is handmade in my pottery studio in Berkshire, UK. The pottery is made in small batches of around 30 pieces and if carefully formed over a two day period. After the pieces have dried for a week, they are then fired to 1000 degrees Celsius in my kiln. I then mix my glazes from powders before dipping and pouring the ceramics to create beautiful glaze patterns. The ceramics is then fired again to 1260 degrees Celsius.
