I checked if I could find a design for 34 cm high as well for Ivo's, but so far no luck. It appears the tallest one they made of this design was 25 cm. They made tall floor vases in the early seventies, but only round ones.

Also, another interesting thing to add to the yellow vase: Wiesenthalhütte apparently only made the 'spectralgelbe' for a very short time. It's only mentioned as a possible colour in the 1967-1968 catalogue, in the 1968-1969 it was already removed from the list. This might indicate that year of design is also year of production in this particular case = 1967-1968.

the design similarity cinches it for mine, I think - even if a 34 cm cannot be documented. There is a very high probability...

I checked the photographs of what I could find. While the 60s examples all seem to have the more pointy surface structure as the yellow vase shows, the later examples from the 70s do seem look a bit more 'stripy', like yours, but mainly at the rim.

Also, the Wiesenthalhütte catalogues look very thorough to me. Each year they made a new one, meticulously added new designs and taking old designs that were no longer in production. They always added a new entry for a new height as well, with a different catalogue number. The 25 cm version of this vase for instance has number 1130, and the 1134 is strictly reserved for the 21 cm version.

And given that this design is not the most difficult to copy, I'm not entirely convinced that it's Wiesenthalhütte. If floor vases came into fashion in the early 70s, some other German factory might have gone back and used the basic idea of this design?

I have no doubt that your piece will glow green under a blacklight.  Several companies have made 'golden amber' or 'honey amber' that glows green.  The way that color is achieved is by increasing the uranium salts from about 2% (normal vaseline/canary yellow glass) to 10% or more.  Here are a couple of examples from WMF:

The little dog figurine is by Boyd in the first link above.  It also glows green and is a contemporary piece.

Thomas Webb also made a similar color.

I even have some cut pieces that glow green.  here is a covered sugar bowl that I obtained recently.

Someplace in my computer, I have info for a patent from about 1925, that describes a patent for a color process that uses a heavy percentage of uranium dioxide to made a 'red henna' coloration.  (think hair dye for the 'henna' color).

I was curious about the amount of beta waves being emitted from a piece that increases the amount of uranium salts.  A friend of mine has a geiger counter and I took a couple of pieces to him for testing.  First, we tested a control piece of regular yellow-green glass.  the setting was set at "1X" and the needle went to about 70 on a range that topped out at 100.  We then tested the honey or golden amber piece.  At '1X', it buried the needle.  at the 10X setting, it buried the needle.  at '100X', it put the needle up to about 70 and clicked away like a cricket farm! 

The radiation emitted is beta waves, which dissipate at a distance of 18-24 inches.  The radiation can be blocked by putting it in a glass cabinet if you are concerned about the radiation.  If it still is a concern, I would gladly offer to reimburse you for your cost and would pay the postage and I could take it off your hands!  LOL

Many thanks for the info, Dave! I have a Wiesenthalhtte vase in spectral gelb, too. Don't
think I checked it, but I'll do when I get home tonight...  :)

I didn't doubt that amber might glow bright green, as I too have several different pieces that do, just that this particular one did. I would be interested to know what Dirk thinks.

Thank you Dave for your interesting contribution!
I saw a green glow only at the cut rim of the vase -- but there it was obvious. So I don't know if this is due to my UV light bulb or due to the fact it is a Manganese glow.
Anyway, in bright daylight the vase looks like a gold bar!

I am sure you and Christine will solve this :)

And I am curious how Dirk's vase in "spectral gelb" will respond...

I just did a UV check and my vase glows brightly - but yellowish orange. Is it Cadmium then?

Sounds like it to me.

My vase is becoming more and more interesting...

While cleaning it today I noticed the green glow even in bright daylight -- so I looked closer, and realized that the vase is actually made of two different coloured layers of glass: an outer thick amber coloured layer, and a thin glowing green layer inside, which looks very much like Uranium to me (that explains perhaps why I saw the green glow under blacklight only at the rim).

Tried my best to capture this on the pics.

Now I know why the vase looks like it had a built-in light -- "spectral gelb" :)
A very elaborate technique IMO (wouldn't have expected that from Wiesenthalhütte).
