Craftsman Style Slag Glass Wall Sconce

This is a wall-mounted exterior light fixture designed in the American Craftsman or Mission style, likely dating from the early to mid-20th century or produced as a high-quality reproduction. The fixture features a heavy, patinated bronze or brass frame with a tiered, truncated pyramidal shade. The shade is composed of amber-colored slag glass panels, held in place by an ornate metal overlay with geometric and quatrefoil-inspired cutouts. The metalwork displays a dark, aged bronze finish with visible verdigris and oxidation, particularly on the wall plate and mounting arm, suggesting long-term exposure to the elements. The construction is robust, utilizing visible square-head bolts and rivets that emphasize its industrial, handcrafted aesthetic. The fixture is supported by a tall, rectangular stem that connects to a flared mounting arm and a rectangular backplate. Condition-wise, the item shows significant surface weathering and patina consistent with outdoor use, but the glass panels appear intact without visible cracks. The internal socket is visible beneath the shade, suggesting a standard Edison bulb base. The high level of detail in the metal casting and the use of authentic slag glass indicate a piece of significant quality and architectural interest.
