Brookfield Green Glass Beehive Insulator

A vintage glass telegraph or telephone insulator, specifically a 'beehive' style design common in the late 19th to early 20th century. This specimen features a vibrant, deep aqua green or teal color, which is a desirable shade among glass collectors. The object is constructed from thick, molded glass with a rounded top dome and deeply recessed ribbing around the middle section to accommodate wire wraps. Embossed lettering is visible near the base, including the brand name 'BROOKFIELD,' which identifies the manufacturer as the Brookfield Glass Company (New York/New Jersey), one of the most prolific American glass insulator producers during the expansion of the electrical and telegraph infrastructure. The bottom edge appears to be 'smooth base,' though some small air bubbles (seeds) are trapped within the glass, characteristic of older industrial glass production methods. The condition shows significant surface wear, including a prominent diagonal stress crack or deep surface scratch on the right side of the dome, along with typical 'flea bites' and minor chipping around the base and wire grooves. A dull film or light patina is present on the lower portion, likely from exposure to the elements or earth burial. This item likely dates from approximately 1890 to 1915.
