Antique Arts & Crafts Era Copper & Green Slag Glass Hanging Light. Material: Copper Frame & Green Slag Glass & Brass Chain. Ca 1900 – 1920. Measurements: approximately 8″ height to top, base measures approximately 12″ square. Condition: good, and works fine….. This lamp was rewired. Notice in the photographs that there are scratches on the copper frame, including a 1.25 scratch (which has a sticky residue) on the upper copper frame. These scratches may not show when the lamp is hung from the ceiling, it just depends on how far the lamp descends from the ceiling. This ceiling light is a nice antique arts & crafts era fixture and gives a nice color when lit. It could hang above the table, or above your desk, or above the game or pool table… You know where your house needs light.
