I've just moved into my new apartment and the previous owner, an old fellow, left this weird glass thing here. It's fairly dusty so I guess it hasn't been used in a while. I'd like to know what is it?

The item is around 7 inches tall.

It's made of glass and has an unknown orange liquid inside.

The item cannot be opened without breaking.

The item was left here by the previous owner of the house, a man who was around 70 years old.

I haven't been able to get in contact with said man.

I've reversed image search and found no results.

I've searched for terms like "old glass liquid recipients", "old glass liquid decorations", "glass filled with liquid ornaments" and such.

I've held it in my palm for over 10 minutes to see if it did anything, it didn't.

In the space of a few months the liquid inside hasn't done anything.

Shaking it also does nothing.

The liquid is runny, similar to water.

It seems fragile.

Are there holes anywhere or is it completely sealed?

Asked a glass blower friend of mine who has blown sclerotic equipment. He did not know but he did say “Lampworked glass for certain likely borosilicate”

We discussed the liquid and he said that sometimes mineral oil is added to closed blown forms to add depth / novelty.

Edit: sclerotic = scientific
