Iron Oxides

"They are the commonest colourants in individual pottery usually giving yellows, browns, blacks and greys. Iron oxide is popular because it can give many colour variations. The oxide responds differently to different glaze recipes and kiln atmospheres. Iron oxide is responsible for the brown colour in red-burning clays."
-The Potter's Dictionary of Materials and Techniques
