Featured Swirl glass vase / bottle ID

On my whirlwind trip into the charity shop I grabbed this on the way past the glass shelf. It’s intriguing as it looks like a bottle within a bottle.
ground at top as if it had a stopper?
c10cm tall
It has the effect like a mirror within a mirror when you look through the flat area if that makes sense Slight AB finish.
Round circle on base but annoyingly no signature. Quite heavy.
Apologies for the water droplets in the last photos, washed it and can’t get them out.
Any ideas if it’s anything interesting or do I banish it back to the charity shop?!
Thanks for any information

 

Answered my own question!
Murano Sommerso perfume bottle. Now I just need a stopper….another one…

 

you might want to try and look up 5th avenue crystal perfume bottle

 

Thankyou
I’m not upset the stopper is missing as they are pretty ugly!!

 

It's definitely a cool piece!

 

That's 5th Avenue, as is the one that bloke sold. It's right that sommerso is the technique.

 

Very nice!

 

It would still make a cute little bud vase.

I take a small strip of paper towel & stuff it into the bottle with a ling applicator stick. Swirl it around with the end of the stick & then gently pull it back out.

Next time use Isopropyl alcohol. It will clean it & any remnants left after the above treatment will evaporate.

 

Thankyou. I’ll add it to the shopping list
