The Magic of Pottery
The three stages of making a piece of pottery
Firstly a pot is either thrown on a wheel, made out of coils, made of slabs or made through pouring a clay mix known as slip. The pot is then left to harden to leather hard. It is then tidied and trimmed ready for the first firing.
The bisque ware is then decorated with a glaze, either through dipping or paining. The clay is then re-fired to a higher temperature, dependant on the type of clay but typically between 1080 and 1250 degrees C. This cycle will take approximately 24 hours before the kiln is cool enough to remove the finished pot/ Always and exciting and slightly nervous event as the glazes are often unpredictable.
The first firing is known as a bisque firing. The clay is typically fired to around 900 degrees C. Bisque ware has then been fired once and has no chemically bonded water left in the clay. Bisque is a true ceramic material, although the clay body has not yet reached maturity. At this stage the clay is typically coloured pink or buff.
