Item DescriptionTitle: Vintage Lancaster Glass Corp. Ohio 7.75" Concave Optical Reflector Mirror DishProduct Overview:
Up for sale is a unique historical estate find from Little Brown House Antiques! This is an authentic vintage 7.75-inch heavy glass concave optical mirror, manufactured by the renowned Lancaster Glass Corporation of Lancaster, Ohio.Featuring a deep 1.75-inch parabolic dish curvature, this heavy piece of precision glass was originally engineered for industrial, military, or scientific magnification use—likely serving as a high-powered reflection mirror for a vintage spot/searchlight, stage light, or technical instrument. The lower front edge features the original etched circular corporate logo mark reading: "Lancaster Glass Corporation - Ohio".With its striking authentic patina, it makes an excellent standalone display piece for an industrial office, a unique addition to a science/optics collection, or a fantastic raw component for a retro-futuristic steampunk design project.Condition Details:

• Overall Structure: Good vintage condition. The glass is incredibly thick, heavy, and structurally sound. The circular rim is entirely free of structural chips, cracks, or deep fleabites.
• Front Surface & Silvering (Notable Wear): The front concave finish remains highly reflective but showcases heavy, authentic vintage patina. As shown in the close-up photos, there are scattered clusters of desilvering spots, pinhead oxidation dots, and fine surface swirling across the reflection field, along with a cluster of oxidation directly underneath the maker's stamp.
• Back Surface: The reverse convex side retains its original, matte-textured silver-gray industrial protective backing paint, which is uniform and clean with only minimal shelf scuffs.
• Maker's Mark: The original etched circular logo stamp on the front remains fully intact, legible, and clear.
