Antique Black Porcelain Door Knob Set – 2⅜" Diameter

Description : This antique door knob set features a pair of glossy black porcelain knobs mounted on an iron spindle. Each knob is 2 ⅜" in diameter and exhibits characteristic surface crazing—tiny hairline cracks in the glaze—common in early 20th-century ceramic hardware. The iron spindle shows expected surface rust, but remains structurally sound. This set represents a classic American hardware style used widely in early residential interiors, from Craftsman bungalows to Victorian-era homes. With its rich dark glaze and rounded profile, it pairs well with rosettes, escutcheons, or backplates of the same era. Era: Early 1900s (circa 1900–1930) Style: Victorian / Craftsman Technique: Kiln-fired porcelain over cast iron base Tools Used: Slip molds, kiln, spindle thread cutter, finishing lathe History: Porcelain knobs like these were prized for their clean finish and durability and were common in both urban homes and rural farmhouses.
