Know something about this?

Another collection...
Anyone familiar with those?

 

the one is obviously from the company Hermann Heye Hamburg.

the other two look around 1900 to me, too.
but better wait till the specialists show up.

 

How tall are they?
The one on the right looks like a replacement top.

 

Mom had a few from these in Italy. used as decantation bottles, origin Florence. height around 30 cm.

 

The green appears to be Depression Era green. The clear bottle is the exact same mold, with the wrong stopper.

Just looked at the link posted by Fid and see that your bottles are shown as Fig. 32 and 33.

 

there you go. didn't make it that far.

 

The uranium glass decanter on the left is much older than the depression era - my call, late 19thc.

 

Approx 30 cm

 

Thanks a lot...

 

Stupid question.... 19thc is before 1900 ? Or around 1900?

19thc is from 1800-1900 although I think you decanter is nearer 1900 than 1800.

 

Not stupid. 19th century = 1801-1900. "Late" 19th cen could refer to the last quarter, or last decade of the century.

 

Is the depression era color.
I don't think these are late 1800s decanters. Style is wrong. Early 1900s.

I should mention I am looking at these from an American point of view. German glass may have been ahead of us.

 

Uranium glass goes back to the ancient Romans!
Admittedly a lot was made during the 20thc, I love my juice squeezer for instance, but uranium has been used in glassmaking for a very long time!
