Throwing, carving and altering porcelain

One of TeachinArt online teachers, Antoinette Badenhorst presented a hands-on workshop at the Pottery Studio in Bryanston South Africa where she demonstrated the carving and altering process of porcelain.

She calls porcelain the "Diva of clay" and tells her students that they have to understand the character of the clay to really push it to it's limits.

Here are some of the characteristics of porcelain.

• When fired correctly, porcelain has a glass like or marble appearance.
• Porcelain has a weak green strength and should therefore be handled with the utmost care before the firing process.
• Porcelain becomes very pyro-plastic (soft because of the heat) at a high temperature. Any thinner parts will collapse when pulled down by the weight of the heavier or thicker parts. It will easily warp or slump during firing. Potters will often times create ways to support a porcelain piece during the firing process to prevent deformation or make sure that the construction is very evenly done and well designed.
