Featured Moser? Help identifying

Hello, i'm new to this site and i hope i'm posting this to the appropriate place. I recently acquired this heavy czech glass decanter with two glasses. It appears to be very similar to other Moser pieces i located online but i cannot find anything about the label on the bottle. Any help would be greatly appreciated! I had to crop the main photo to bring it below the upload size cap.
thank you!

 

Welcome @j thomas . Very nice set.
I will tag someone who may be able to help you, @Ownedbybear .

 

I wouldn't know, but it sure is pretty. I'd try taking a glass out in daylight and see if it's a different color. Then run it under a fluorescent bulb (not one of the new ones) and see what you get. A color change doesn't mean Moser, but it does mean neodynum glass.

 

Oskar Pursch ?

 

The word is neodymium. It's a rare earth element added to glass to achieve colour change in different light temperatures. It goes blue to lilac. Other rare earths do different changes.

I agree with Fid.

Lovely set.

 

Joolies call it alexandrite glass; my brain farted on the chemical name.

 

It gets called alexandrite by glass peeps, too. I'm as much a chemistry geek as a botany one.

 

When I hear Neodymium I have to ask myself "OK, is this a piece of glass or a magnet". Old school speaker magnets are neodymium, as a magnet fishing devices. (magnet fishing is a sort of fun way to clean iron-based junk out of rivers, streams, lakes etc. Fun if you're dead bored, like regular fishing, only you don't have to worry about size limits or bag limits.)

 

Magnet fishing is huge here. London canals are full of all sorts of weird stuff.

 

I guess when an area's been indistrialized for 250 years there's no telling what's gone over the side.

 

There's a tendency to find the odd unexploded bomb or two, we've a few of those still.

 

Oops. Not sure I'd want to hook into one of those! Unstable explosives aren't my idea of a good time.

 

Huge ones are still found: builders unearthed a 500 lb one not that far from me about four years ago.

 

Some of them make the papers even over here. I wouldn't have wanted to hit that thing with a bulldozer. Talk about digging a foundation hole the hard way.
