A popular Japanese tea cup shape called a yunomi. Soft undulating grooves on the side allows fingers to comfortably handle the cup. This is wood fired to cone10+ with a reduction atomosphere and a heavy natural ash glaze. Like many handmade pieces in natural firings, this is unique and while you can try to produce the same one, they will only have a "family resemblance".
