Topic: Cameo? Glass lamp shade

[uncommonglass]

This shade is 4.5 inches tall and the floral pattern is "raised" a bare fraction from the rest of the shade. I've not handled much cameo glass.   The small opening is about 1 inch.  The green shading isn't painted on.  Might it be french origins?  (very hard to see in photos that it's raised, but I tried in the closeup)

Thanks!!

Design is probably printed on with transfer and the material used to print is essentially pulverised glass in a flux. The green most likely stained but might be flashed.

Frank - Thank you so much for all your help - on this and the white one and for cheering me on with the Temple lamp part.  Alas, I did not find the right oil lamp, but dang, I didn't come home empty handed either   I hope you don't mind if I hug {{{you}}}

Lampshades are one of my interests that pre-dates my glass interest, restoring and selling lamps was my main line late 70s early 80s and in the last ten years I have been piling up catalogues of lighting glassware as well as electrical wholesalers... all in the queue for digitising. Unlike glassware design change was a lot more dynamic and more closely linked to fashion - less useful is that who made them is mostly lost as they would have been commissioned on price competition and of course styles were very widely copied. Although I am as interested in the bulbs inside the shade. http://www.debook.com/Bulbs/lightbulbs.htm another project on hold at the moment.

Oh my, another lamp addict enthusiast!  I have more lamps than I could possibly ever need, but I bring more home whenever I find them.  They need to be glass though, either the shade or the base.  But I'll also rescue spelter floor lamps when needed.   I'm an innocent babe compared to your knowledge, but I do know "mogul" and Mazda!

Do you think these shades were for gas or electric or could be either?

Gas shades are generally smaller and oil lamp shades larger as a chimney had to fit inside. Electric shades were not really used much before say 1905 as the cost of lighting was so high that people wanted everyone to know it was electric. But by 1910 they were probably the fastest growing sector in glass after light bulbs, paradoxically the huge demand for glass-blowers triggered the demise of many glassworks as that growth continued - this was because of automation and the bulb companies own factories no longer need to outsource production. Gas shades might get used just to cover the fitting and bulb base. Gas shades with smaller holes wee uplighters, downlighters were attached to a gallery and had a large opening with a collared lip, Oil shades did not have a lip - although there are exceptions. Most of the catalogues split them into those different categories. Their are also odd shades that were used on arc lamps but they are fairly rare.

Edinburgh crystal made some weird electric shades that were flashed in colours on the outside and then silvered over the colours, I have never seen any of those.

I used to restore early rise and fall units and still have a couple waiting for some spare time. But apart from that mostly just gathering reference materials.
