Charcoal is a flux that is added to ceramic bodies and glazes. It is made up of vegetable products that are burnt and then broken down into a fine powder. Being a vegetable product, when fired, it burns away. For this reason it is used to mark designs on to clay, bisque and glaze-bases. It can be bought prepared to use in different ways, sticks, pencils and powder. You can make the powder by burning a wooden fruit box, breaking the ash down and sieving it.
