I donated a purchase prize at the first KC Clay Guild Teabowl National last year and this is what I chose.
It comes in two pieces.
The base is 1.5 x 2 x 2". It is made of porcelain, unglazed, rough formed to hold the teabowl.
The 'teabowl' is 4.25 x 3.5 x 3.5". It is also made of porcelain. It is glazed inside onlyand it looks like a clear glaze. This piece was thrown. I queston whether it was thrown from widest pot to the tip (upside-down) or from the smallest point to the mouth. Jim's website states that after his 'sabbatical' he began firing in a friend's anagama kiln. Is this a wood fired piece???
