Notes

Every potter wants a good reliable glossy black glaze that has a minimum of toxic metals and fires to an even color without pinholes and blisters. Ravenscrag slip has the unusual ability to host a black color from a high iron content (only a tiny amount of cobalt oxide and chrome oxide are needed).
