Featured Pair Small Stained-Glass, Copper Foil Lamp Shades

Went to a local flea market for the first time in well over 3 years Saturday...I've largely abstained from such temptation, since I have enough stuff already. But these caught my eye, an' I brought 'em home. I have no illusions about age; they are pretty contemporary imo, but I thought their simplicity an' the quality of their craft a bargain at their modest price, $10 for the pair. You are only seeing one, as they are identical in all respects.
My recollection of this faddish hobby is from the 70's, or perhaps a bit earlier; I never got into it, but several folks of my acquaintance, an' one sister-in-law, were deeply involved, tho' none could match the level of skill shown in these; the soldering is minimal, without any excess, an' is 'patinated' by a black treatment inside an' out, all very uniformly done. Something about the colors an' the pattern are reminiscent, to me, of Frank Lloyd Wright, but I cannot bring that into good focus.
The square is ~10 1/2", they are ~6" high, an the vented top is 2 3/4" on a side. Each side has 22 pieces; the darker triangles have an iridescent sheen, an' the short dark rectangles in the stripe that separates the skirt border are a rich amber. Is there anything here that harkens to a higher, perhaps borrowed, design? I welcome your comments; Thanks for lookin'!

 

talented amateur , at the least.
they don't look to be copper foiled , so not the Tiffany style..

a 10 for the pair......... not bad at all !!!

 

They aren't channeled lead...If not copper, then what, Komo? I profess ignorance aplenty about this.

 

copper foil used under the lead channel......
look closely at yours for the signs of this foil.....where the lead is thin, or disturbed...

 

Ten smackers for the pairs mighty good. These'd look good on a pair of simple metal or oak Arts & Crafts restrained 'Prairie School' style bases.
Glad you got out and hit the local Flea-our PNW deluge is coming Whit, jump on those outdoor markets before our normal tsunami hits !

 

I think the glass is called 'slag glass', but need confirmation from someone more knowledgable on glass.

 

Yes! I think you're right, AJ. Thanks!

 

These do look like copper foil to me. Think probably 90s or later. Mass produced and likely from China. Probably came on a lamp or chandelier. Part of the Arts and Crafts reproduction phase going on at the time. Similar to what Dale Tiffany was doing but all the big box stores had unbranded lamps soon after.

 

Here is what looks to be the same on a small lamp
