Antique Hemingray No. 40 Aqua Petticoat Insulator

The details

This antique Hemingray glass insulator features the classic petticoat-style skirt that made these pieces so iconic on telegraph and telephone lines across America in the early 1900s. Embossed HEMINGRAY No 40 on one side and PATENT MAY 2 1893 on the other, with drip points around the base, this example showcases a rich aqua green tone with visible bubbles and swirls throughout the glass — natural characteristics that make each piece individual and prized among insulator collectors. At approximately 3.75 inches tall and 3 inches in diameter, it's a substantial piece. The glass shows no cracks, with only minor wear consistent with honest age and outdoor use. The deep color and internal movement in the glass catch the light beautifully. Display it on a windowsill to let the aqua tone glow, pair it with other telegraph-era insulators in a collection, or let it stand alone as a piece of American communications history. A thoughtful gift for history buffs, insulator collectors, or anyone drawn to vintage industrial glassware.
