Studio Ceramic Series: Painting the Bowls
Today I made ceramic high-fire paint, called engobe, to paint the bowls I made this week. I made 7 different paints: a soft turquoise, a stronger turquoise, a soft blue, a stronger blue, a rust brown, a soft green, and a white. This paint is made by mixing grog (fired clay which has been milled to a fine powder) and clay powder. To this mixture we add oxides -- chrome, cobalt, iron and copper -- and carbonates (copper and cobalt --- these are the softer colors) and dilute the mixtures with water. In the picture above, the bowl to the left was painted with cobalt oxide engobe, the next with iron oxide, the third with chrome oxide, and the fourth with copper oxide.
