This salt-fired porcelain bowl by Karen Newgard is 11″ in diameter and 3 1/2″ tall. Karen Newgard makes her pots on an English style treadle wheel. Once the form is “bone dry”, she brushes terra sigalatta with stain in it to the pot. She carves through the terra sigalatta into the porcelain pot with a small loop tool. Then the pot is bisque fired, she adds glaze to some of the interiors and other parts of her pottery. Then she fires the piece to 2350 degrees fahrenheit . Once this temperature is reached, she introduces table salt to the kiln. This interacts with the silica in the clay to form a glassy surface that seals the clay.
