How does Raku firing change the texture of clay?
During a Raku firing, volatile portions of compounds and molecules in the clay/glaze breaks free and the free oxygen attaches to the remaining material. This forms what is called oxides. This process is called oxidation. The oxidation alters the color of the glaze and also changes the texture of your clay. The changes can sometimes be dramatic.
