Deposé France French Celluloid Brooch
Found this cute ’lil French celluloid brooch lurking in a bag of broken jewelry at the Value Village. It’s actually two disks set on top of one another to create depth. The back is marked “Deposé France.”
Celluloid is pretty much the first thermoplastic,(created in 1862). Because celluloid is easily molded and shaped, and it was first widely used as an ivory replacement. This particular style of faux ivory, faux carved bijoux were quite popular in the 1920s and 1930s because they were cheaply made.
They are also sort of collectible because celluloid is such an unstable substance. It’s highly flammable and it decomposes so finding a piece in good repair is hardish.
