Thanks Glen,
I hadnt gone down the Scandinavian route!
its hard to describe this one, the glass has a molten feel to it, like its oozed down
to the base, its so smooth, but near the base you can see where it was molten at
some stage! and as i say its hollow, and has a very organic ,liquidy fluid feel to it, and near the
base, the inside and outside blend together!
I feel some sort of mould was involved, and then the hot glass was cooled fairly quickly,
but i really have no idea

Im still sure the base may give a clue?
Andy
