In the photos are a pair of vintage green slag glass hanging pendant light, often referred to as a tulip or lotus lamp due to the shape of the shade. These lights are made in the Tiffany style but are not necessarily original Tiffany productions; they were widely popular in the mid-20th century, particularly the 1960s and 1970s. The shades feature slag glass panels that appear green when unlit but take on a yellow tone when illuminated. Each petal is lined with beaded brass trim, consistent with an Art Nouveau or mid-20th-century style. Material: The shade is made of slag glass (also known as marble or malachite glass), which is an opaque, streaked pressed glass created by adding metal ore to molten glass to create a marbled effect. Design: The shade features distinct panels assembled with metal framing, forming a flower or tulip shape with a green and pale amber/yellow swirl pattern. Both in working condition and will require some repairs to the brass trim.
