This is a vintage dark brown glazed ceramic insulator, likely used for electrical or telegraph lines. It features a classic two-skirt design with a rich, deep brown glaze that shows some iridescent blue/purple hues in certain lighting. The insulator is in good vintage condition with expected wear, including some minor surface scuffs and a few small chips consistent with age and past use. The interior is threaded for a pin-type application. It measures approximately 4.5 inches tall, making it a great piece for collectors of insulators or as unique rustic decor.
