Hello Linsmins, welcome to the board. I've split your ID request out of the Themes topic, so we can take a look at it. ID requests should be posted as new topics in Glass please, unless you are sharing images of your collection of parts of it (i.e. themes) just for the pleasure of sharing them, in which case they can go into the Themes topic.
Your vase is of the shape known as a jack in the pulpit vase (abbreviated to JIP often). Can you add a picture of the base please as this often tells us much about a piece, even if it's unsigned or unmarked. Also, does the vase glow if you light it with a UV / black light? And would you add dimensions too, the more info we have the more we can help. Thanks!
