Topic: Small Venetian or Murano Glass Age Help Please

[RoyJ99]

Picked up this little glass in a mixed lot at auction today. Most of the glasses were late Victorian or Edwardian, standard drinking vessels but I bought the lot because I liked this. I would guess it is Venetian or Murano in origin however I have no idea how to date such glass. The base is quite this with an unpolished rough pontil mark and the wrythen/twisted stem has a tear drop shape bubble inside. I'm at a friends and can't find a ruler anywhere but I'd estimate the height at about 7cm.
