These cups were once fired (fired green) for 2 days with Japanese red pine in the mountains of Nara Japan. The layered look of the clay, white overslip and finally the clear overglaze. The clear overglaze on these cups has completely melted as compared to other white slip firing from my kiln. It will age nicely if used and taken care of. I can include a signed box for a minimal extra fee. Size. diameter 3 in. (7 cm) by height 4 in. (9.5 cm) weight 11 oz. (310 gm) I will combine shipping and I can send express mail. Please ask me for a price. The shipping price is non insured, non trackable. 19$ will get you EMS which is trackable and insured. Thank you.
