Depression Glass Insulator Appraisal

Hemingray No. 95 Glass Insulator

This item is a clear glass electrical insulator, specifically a Hemingray No. 95, based on the embossed lettering clearly visible around the base. It is constructed from a robust, translucent glass, exhibiting a very faint greenish or bluish tint, characteristic of earlier glass manufacturing processes and impurities in the silica. The overall form is typical of a spool-style or 'pony' insulator, designed for securely holding electrical wires on utility poles. Physically, it features a rounded top or dome, below which the body tapers slightly inward before flaring out to a broader base. The central part of the insulator is threaded internally, designed to screw onto a pin. These threads are clearly visible through the clear glass, spiraling downwards. The surface appears smooth, though consistent with molded glass, minor seam lines might be present but are not clearly discernible in the provided image. There are no obvious cracks or large chips; however, some surface wear, scuffs, and possibly some dirt or discoloration, particularly around the top and base, are noticeable, consistent with age and previous outdoor use. Small black specks on the top dome could be dirt or minor imperfections. The embossed 'HEMINGRAY' and '95' confirm its maker and model number, indicating a manufacturing origin from the Hemingray Glass Company, a prominent producer of insulators during the late 19th and early 20th centuries. The '95' typically refers to the style or size. Given its common clear glass composition and style, this insulator likely dates from the late 1890s through the mid-20th century, though dating would be more precise with mold numbers or drip points. The craftsmanship is functional, typical of mass-produced industrial glass, designed for utility rather than aesthetic perfection. The glass quality suggests a dependable, durable item for its intended purpose.
