Shibuya Eiichi, the grandson of a known Hagi Artist Shibuya Deishi, is certainly making splashes in certain circles namely those on Teachat which possibly houses the largest collection of Hagi Yaki lovers in the West. It is pieces like his Rocks that honestly show why. While I had always found the rocks visually stunning, I had held off purchasing one on beliefs that it might be a bit more of a show piece than an actual functional piece.
Let me assure you those fears were ill placed, although I will warn that the rocks are not very hot water friendly. They are easily usable with the temperatures necessary for Green tea, but I hear they are quite the finger burner when used with near boiling water.
This piece came from a Teachat Super Special Offer, and was piece number 1 from that offering (not my first pick, but I was quite smitten by just about all of them). These were the first batch of rocks that were done by pinch work (tebineri), and I would have to go back and look at pictures but this one gives a distinctive chamfered look to it, with slightly extra build up to give the full on rock appearance.
In full fledged High praise this might easily be in the running for one of my favorite teacups, in stiff competition with some wonderful pieces, but it clearly holds its own.
