The body is a red-burning stoneware we are formulating for cone 5. The glaze is a mix of 75% G2934 and 25% G2926B. The latter is a glossy, the former a matte, this mix achieves a silky matte (although here it is a little too glossy, next time we will do an 80:20 mix). The additions, to 100 parts-by-weight of this mix, are 1 part red iron oxide, 5 tin oxide and 1.2 rutile. The firing is C5DHSC, a drop-and-hold plus slow-cool at cone 5. The inside glaze is L3500G. This glaze is much better suited to use on a dark-burning body, its oatmeal color is lost on lighter clays (although, of course, you could add more iron and/or rutile).

Also called "middle temperature" by potters, cone 5 (~2160F/1180C) refers to the low end of the temperature range at which most hobby and pottery stonewares and porcelains are fired. |
