This is Plainsman Raku. It has 18% 35-65 mesh grog, 65% Plainsman A3 buff stoneware clay, 14% Pyrax and 3% bentonite. Throwing it on a pottery wheel affords a better sense of the texture than any other method. Apparent texture is a product of a combination of particulate percentage, the distribution of particle sizes, particle shape and distribution of shapes, particle surface topology and the nature of the clay matrix they exist in.
Gas fired rustic ceramic ware is cooled from red-hot in a closed container with organic material. The zero-oxygen atmosphere produced reduces carbonate metal decoration to its metallic form.
