I am clueless. I don't recognise any part or particle of the style or methods used.
Making swirls within lines, by pulling the surface of the glass around while still hot was a technique used by Monart, Vasart, Strathearn and Perthshire, also by Isle of Wight Studio glass, Nazeing, Grey-Stan that I know of, and there must be others, I am sure, in the uk.
It looks very modern, and a very well made thing, and I want to know who made it too!
