Glass vase help please

I know very little about glass so any help you can give is ever so much appreciated. Sorry about my bad photos. It's pouring down rain outside, and I have no good light for picture taking right now.
Is the term called threaded?
The vase has a bit of iridescence to it, and is white on the inside. Looks a bit more pink/purple ish than pics show. Stands about 10 3/4" high. Has a polished pontil.
Thanks for your time.

 

It's cased white and irridescent glass with trailed decoration and it's footed. I don't think any great age, probably gift ware, but it's pretty.

 

Thanks so much OBB, much appreciated.
Bummer, I thought it was quality glass, because it feels so nice.

 

Oh, it's decent quality - but the value is in its decorativeness, really!

 

Thanks OBB I really appreciate the help.

 

You're very welcome.
