How old is this shade and what type of vase?

I like this shade a lot but really don't like the base..

How old do yall think the shade is and what type of base would it originally have had?

 

I don't know anything but maybe art nouveau or later. The finial looks like a replacement.

 

Thanks to this I've been looking at all sorts of slag glass lamps I never knew existed, and I love them. Did you show the base of yours? I don't see it.

 

It looks like the copper-colored finial may match the piece directly underneath the shade. It looks like the shade may date to the 1920s or 30s, but it may have been made by a hobbyist. I've certainly never seen one quite like it.

 

It sort of looks like agate glass, but that is just a guess.

 

Slag glass shade. Don't ask me when it was made.

 

The base is definitely new so I didn't take a picture of it.
, it's currently being used as a floor lamp, I didn't know if it was Ridglea supposed to be a floor lamp because it is so large or if it would have had a base for a table lamp.
I knew it was slag glass, my guess was the early nineteen-hundreds to the twenties.

It's marked at $175 and I think that's a little high for just a shade because the base really doesn't match and I'd have to find a new one for it but have no idea what it would look like

 

It is an odd one. I almost wonder if someone made this to use those glass panels, which are more typical for a cast frame.

 

The glass is a form of sheet(window) glass commonly called "cathedral glass" by the makers. It is the kind of glass found in church windows where it is called stained glass by the glaziers and designers. The upper panels were formed by a slumping technique into a form. Likely the lamp dates to the 1920-30 period and was a production item. The repairs are not professional. Yes I know it looks lake slag glass used for tableware and decorative object but the terminology differs in the separate industries.
