Topic: (Themed) glass displays - show me yours, I'll show you mine... part 4

Another hint... with gas you are so near like no one before

And it is a flattened bulb, like an UFO. The stopper is glued

Is it part of a flowmeter? (something for measuring how much gas passes or is released?)
I'm going to be dreaming about it tonight! 

[BlueOctopus]

No part of a flowmeter... nice dreams. I guess this is very unik, these sort of glasses did not survive offen.
Onother hint: it is a oneway glass

All I can come up with is a lid for a large flask (5l size) containing 2l of culture medium and a culture of bacteria for incubation.
But when i did that - I made a stopper out of a large cotton wool ball covered in aluminium foil and tied with string around the neck.

Or on top of something fermenting. I have been dreaming of beige yeasty beery froth bubbling up under it in a large test tube.

No, as I said, when I found it, it had a label. It was just an „ordinary“ flask for selling gas. The label said 99,9999 pure Argon gas. The metal lid is sealed, but on the top it has a small little opening where you can go  through with a gas tight siringe and suck the gas out. Maybe there is still a little bit Argon in 

I think 100 years ago these sort of gas was very costly so you could buy in these small amounts.

Aaah - something similar to glass balls containing water, for throwing at a fire.
Target balls. More info and some lab stuff in this link.

Not terribly effective, they were made under the name Monax who also made lab glass and lighting and domestic crockery.

in my defence,  I didn't know there was any access to the inside of the container - I did think it was completely sealed.

[BlueOctopus]

You are right, my photo is a bit dizzy where the little entrance is. Hard to see

These target balls are crazy, Asterix would say: the British are a little nuts

[chopin-liszt]

The target balls are more Geriatrix. 
Without glass, we wouldn't have science. Prisms, Layden jars and Bell jars were all essential for modern science to begin.

Because it's Sunday and I've nothing better to do whilst waiting for the in-laws to arrive, thought I'd share my current coffee table display of textured glass. Couple of Kosta snowball votives, couple of Liskeard, vases, a Whitefriars, a Riihimaki, and a big lump of sommerso Murano whose maker I did identify many years ago, but whom I have now forgotten and can't find the link.

Like the display, this is our coffee table at the moment
