Nice old translucent milk white glass shade, a huge heavy domed pendant shade for an antique ceiling light fixture. This isn't marked that we could find, but it looks like a Brascolite piece to us.
The shade measures 14" across at the rim, and is 8" deep. Three hooks mounted through the shade hold this from three heavy chains. The chains are now very rusty, and we aren't sure if they are the original hardware, or not? They are very utilitarian, and would be in keeping with an early industrial light, or a light in a commerical setting, but it seems a shame to hold such a beautiful shade from plain iron chain.
The shade is in excellent condition without chips or cracks, the metal hooks and chain are very rusty looking, though solid.
