I can't say for certain now, need to ask for better translation. Seems this is the result of his firing, color is because of big difference in temperature of inside and outside of pot. Something like ~1300C outside pot and 1800 inside, but wonder if i got this right, feels way too big differencehopeofdawn wrote:Gorgeous clay--love the contrast of the interior against the white glaze of the outside!

One downside to this piece, it's rather expensive, well, as everything purely handmade in Japan. Would like a set of cups with it, but this will have to wait.
