Green Mica Bridge Lampshades are a Craftsman era design. The natural organic appearance displays flecks of green, gold and brown. For extra pop, these bridge lampshades, are bordered with a nut-brown braided trim. The braid displays a faux leather appearance. A semi-transparent outward glow is produced when lit. Yet the downward light for task lighting is bright.
Mica refers to a group of minerals. These silicate minerals are heat-resistant, do not conduct electricity and appear in various colors. The sheet mica is made by laminating mica flakes - crystals together with shellac or resin.
Green mica lamp shades are made on a copper-brown metal frame that is rust resistant. The shape is round. Frame is wrapped with sheet mica. Once made, mica-sheets are rigid.

Compatibility between Bridge Lamp-shade and Lamp-socket
Uno-threads, on new and old lamp sockets, can vary slightly.
Most sockets and shades will thread together, however occasionally the threading on some sockets is not compatible.
To insure compatibility, between threads on uno lamp shade and threads on. uno socket, it is best to purchase socket and lamp shade together.

The shade was expensive but looks really nice on the antique base. It was tricky to get all the parts together. Instructions on the web site and one other we found were helpful. I would do it again on another old lamp.
