That's very nice Greg! Lovely colours and execution. Weird that it's not signed.
Gillies Jones came to mind but I'm sure they always sign and I don't know about the pontil mark. (Trying to remember another name of maker ... Paul Bar
? not sure I've got that right but he made some beautiful bowls and I'm trying to remember if the pontil mark was left like that on the one I had.) edit .. twas Paul Barcroft I was thinking of and I think his pontil marks are polished actually - and he seems to sign
That's the only thing that stands out to me .. if it was going to show like that, then why not have it polished (obviously if there are no facilities in the workshop then that's why, but you know what I mean).
But love the way the blower has layered the colours internally and externally. It works beautifully.
