What is Iron Oxide?

Adding Iron to achieve buff

Recently I heard from someone who liked the feel of throwing a white stoneware however the specific application was using a glaze called 'butter' which comes out a beautiful creamy white to light brown. It looks better on a clay body which contains some iron as it produces iron spots and helps bring out the brown color. White stoneware has less iron and impurities than stoneware so to get the butter glaze to come out in a white stoneware our experts suggested to try mixing iron oxide into the clay we were preparing for the day beginning with a small quantity such as 1 teaspoon. Iron will help to bring out variations and brown spots in the glaze.
