Hi,
Interesting vase but nothing like my usual stuff! I have no idea where to start with this - cannot find anything that resembles it

11" high, top diameter 3.25", circumference at fattest 21.75" - slightly lop sided, base diameter just over 2.25".
Beautifully ground out pontil mark and base and polished - age wear to base.
Extremely heavy - suspect high lead content.
The rim is cut and polished (not sure of the exact terminology - sorry) and approx 9mm thick.
It appears to have an inner layer (approx 1.5mm) which is very speckly with small blobs of colour, only a very few small air bubbles. there then appears to be a thick clear casing, on the surface of which the coloured enamels have been applied (you can feel the texture) - this gives a sort of 3D aspect to the glass.
Any ideas much appreciated,
Roberta
