I have no idea who could have made this piece of art glass but it is to beautiful to go without getting noticed. Maybe it is just a cheap knockoff by some unknown. Anybody have any ideas? It is 91/2" tall and about 11" long. TIA :)

Well maybe the pictures would help :P

Hi,
Is this dichroic glass? Changes colour in different lighting conditions?
I know where the colour tells me this is from, as well as the finished foot, but will hold back until you indicate whether the above property exists.

I thought the same thing but I don't remember what colors it should change to or what light. For exameple taking it from indoor light to the outside should that make it change? Or putting under a black light would that make it change also? What colors schould to? Thanks for your help can't wait to hear back from you.

It should change to blue under a fluorescent light because it looks to me to be neodymium glass
-
It should change simply between artificial (either standard bulbs or fluorescent) and natural light sources.
I cannot comment on black-light (UV), as I never use it.
If it does change, in the light of Lustrousstone's comment above, then among the prime candidates will be Zelezny Brodske Sklo or ZBS, located in the Czech Republic.

No Marcus. It will be the same in daylight as under incandescent (ordinary light bulbs and halogens) sources when it will be purple, but different under fluoresent (strips and low-energy) sources when it will be blue. I always have to check using my little lilac cat.

Doh.....
I knew I'd get it wrong :-[

I agree. A quick diagnostic test for distinguishing neodymium glass is to look at a solar reflection spectrum from a shovelware CD. When you interpose the glass it will filter out all the yellow light with a weaker absorption line in the green.
If you have low pressure sodium street lighting the effect of look at them through neodymium glass is startling (just like glass workers goggles it blocks the bright yellow sodium D-lines).
The result of this very strong minus-yellow filtration is that the piece will look very different even grey under sunlight, pink under warmer incandescent lights and almost green under fluorescents.

loveglass - Where are you located? US? UK?
Several US companies made similar pieces in neodymium glass also - most notably US Glass/Tiffin. I am not saying it isn't Czech but there are other possibilities.
Could you please show a picture of it from the side - straight on - 90 deg.?

I live in the United States and here is a side view of the piece. I am having trouble with the color change, my house is almost all windows so this looks blue from the side, which would be from natural light, last night when it was dark and under regular lights it look way more purple. Right now looking at it at different angles you are getting blue and purple. Thanks so much for the help!!!

Definitely brass and iron. ;)

:o OMG you would think I could get this right! Speaking of turning I just truned to red :-[ Can't seem to get the picture hosting to work, I know I got the wrong picture, and that is my fault, but now it won't let me in at all. I had to use desk top doctor to try and fix it and it still won't work. But if this peice of glass can turn into andirons do you think I could get it to turn to gold? :D I could use about 20 pounds of gold right now. Anyway I will keep trying to get the picture link to work.

Ok here is the side view and by the way thanks for help! :clap: :clap:

Thank you for the side view. After comparing your side view to the pieces that I was thinking about - Tiffin Free Form bowls as shown in Tiffin Modern Mid-Century Art Glass by Hemminger, Goshe, and Pina - I do not think it is Tiffin.
The base is too small in proportion to the size of the bowl to fit with the Tiffin pieces. :-\

:) Thnaks Connie I guess this one might take awhile before I find out who made it.

Marcus has given you a likely candidate if your glass changes between purple and blue under different conditions of artificial light
