Topic: Monart / Vasart 'ink bottle' find verification

It's the getting of copper particles into the glass that gets me worried about reactions - not the fact that once it's in, it will be fine, and oxygen is sealed away from it.

Thanks for the info about small labels, Gary! I'll ask a moderator to put a score through my wrong comment - I don't want to leave misinformation there.

The link isn't quite right, but you can get to the right place from it.
I knew oxygen in the air was a problem - I just didn't consider that it can be removed. 

It explains other colours of aventurine too, I did know green came from Chromium, because that's how it sometimes ended up in bits of Monart - it appeared because of a chromium scum that accidentally got on top of the pot.

hi again all,
I really appreciate all your responses and glad we cleared up that 'gold' aventurine issue John , which I keep seeing everywhere. Regarding the shape Gary I have attached more photos hopefully that helps. I think the canes were also identified from an IE bottle if I recall so that would fit perfectly if it turns out to be that shape if they worked in batches. By chance I have tested with a UV light as my wee keyring light arrived yesterday for testing a Galliano Ferro sommerso bowl that I picked up which turned out to be uranium, however nothing showed up on this bottle. When you say early Monart is it possible to date with any certainty and make it an elder Salvadore or a young Paul (or other brother) piece or did they collaborate i.e stoppers by Paul for example. Just curious how long till its a proper antique? I have to say I'm pleased to find some Scottish glass with some history, since I am in Aberdeen it didn't travel too far...
regards and thanks again to all

Definitions of "proper antique" can vary. Some say 100 years, it certainly used to be that, but I think 70 years is now considered enough.

Hi Barry, thanks for extra images. Your piece is shape HE and was made between 1924 to 1939.
