Hi Guys, thanks for looking.
I have been trying to research this lovely vase which 13" tall and has an iridescence to it.
The base has a ground and highly polished pontil and has age related wear.
This vase looks the shape of LOETZ ‘Chine’ Vase, seen here,
http://www.nouveauglass.co.uk/archived/loetz-chine-vase-2/Chine is the name for this type of applied decoration which my vase does not have.
Is this Loetz or something else? Does it date from 1900?
Cheers Wolfie
