Topic: Is this a Zelezny Brod vase?

[Wayne]

Uranium glass is definitely less common in Czech glass it seems.  In fact those 2 Skrdlovice pieces are the only 2 I can recall seeing myself.  I've never seen any Zelezny Brod/Chribska/Mstisov etc in uranium.  It would be quite interesting to see more uranium Czech glass if it exists.  Maybe there is more out there than we realise, and people just aren't used to checking for it?

As Wayne said, the uranium free hand glass was rare in Czechoslovakian free hand glass production, I do not expect that this piece is Czech.
I have seen pictures of uranium glass piece attributed to Skrdlovice, but I have no evidence about using uranium colours there.

Hi Jindrich,
I'm happy to believe my vase is Murano and I think it's a lovely piece  .  I don't have anything even close to the experience of Czechoslovakian glass you have.  I've had one piece of Czech glass with a uranium tint and a lot which didn't.  I even had a citrine art deco decanter set which looked very much like the oily yellow uranium tint but wasn't - it had no glow at all in uv (shown below).  The one I saw a uranium tint on is also below.  I'm not debating the Murano vase, just interested in what's known about the use of uranium in Czechoslovakian glass.  Maybe the rule of thumb is that if it has a uranium tint it is unlikely to be from Czechoslovakia.
I think Wayne's point that maybe people don't check for uranium glass in Czech glass is interesting.

Not really, Uranium glass had been popular here in 19th century, i suppose that this uranium colour has its origin somehow here in Bohemia, but I am not sure. Surely in Czechoslovakia were the big resources of uranium until Russians had stolen it. :-)

Simply this colour had not been used for hutni, its all. Recent products from Schubert Glass or from Desna are from uranium again.

Jindrich is saying that uranium wasn't much used in hot worked hand-made glass of the period he is interested in. However, it was used very extensively in Czechoslovakian pressed and mould blown glass, including in beads, probably into the 1950s. It's still being used today by Desna for pressed items.

Pre-1918 it was used for everything in the areas that later became Czechoslovkia.

That makes sense; that it was used in pressed and mould-blown glass.  Particularly with the local Uranium deposits.  I wonder why it was less popular for hot worked glass?  I know having it around the house isn't a particular health hazard, maybe working with it all the time is less healthy.  I found another example of hot-worked uranium glass I'd forgotten about.  I think it's Skrdlovice.

Just ignore the label on the photo.  I'm trying to stop myself using 'Sklo' when I mean Czech glass (I do listen really).
