Tom Young, m but I don't think it's his work - his tends to be less heavily coloured, but this piece I would have no doubt attributing to Ed Iglehart. (sorry Ivo)
The decor is absolutely correct.
I have an oil lamp which has this base shape, he does sometimes finish vessels with what looks a bit like a heat finished pontil mark, but sometimes the base is smooth and shiney with circular ripples (maybe really well heat finished?) and sometimes it's a great, deep pocket - I've just checked the finishes on 4 different vessel - shaped pieces.
Do you know anything about Ed, Ming? Have you seen his website?
He does his best to recycle stuff, he uses copper from old electric wires to colour the glass..
