Slag Glass Sconce Appraisal

Mission Style Slag Glass Wall Sconce

This is an outdoor wall-mounted lighting fixture designed in the Arts and Crafts or Mission style. The fixture features a geometric, tapered four-sided shade constructed of a dark-patinated metal frame, likely copper or bronze, with integrated decorative 'X' overlays. The shade is inset with amber-swirl slag glass panels that provide a warm, diffused glow. The metalwork exhibits a rustic, hand-hammered appearance with decorative square rivet heads or pyramid studs on the upper and lower bands of the shade. The arm is a vertical, rectangular pillared support with a pointed 'pencil' tip base, connecting to a rectangular backplate secured by four chunky bolts. The condition shows significant weathering, consistent with outdoor exposure; there is a visible green verdigris patina forming on the metal surfaces, particularly near the top, and some dust/dirt accumulation on the glass. The socket is a standard brass screw-in type, visible from the bottom view. This piece mimics early 20th-century American craftsmanship, potentially dating from the late 20th century to contemporary based on the mounting style and wiring components. The heavy construction and stylized geometry are hallmarks of the Craftsman aesthetic.
