This is a cone 6 stoneware mug made using Plainsman M340. It is 100% raw clays mined from the Whitemud formation in the Ravenscrag area of southwestern Saskatchewan. The clay surface can be made white or black using our L3954B engobe. In this case the black version has been applied at the leather hard stage (by pour-in, pour-out on the inside and dipping on the outside). The GA6-B transparent amber base glaze is made using ~80% Canadian and Mexican-made ingredients.
