A beautiful mid-19th century pressed glass whale oil lamp, likely produced by the Westmoreland Glass Company. The lamp features a tiered hexagonal font with deep molded panels, a clear glass ball stem, and a faceted base that catches the light beautifully. Its precise mold work and balanced proportions reflect the refined craftsmanship of American glassmaking during the period. This example demonstrates the transition from purely functional lighting to decorative household objects, with form and symmetry that speak to early Victorian sensibilities. The clear, brilliant glass and crisp detailing highlight the quality of the molds used by leading mid-Atlantic manufacturers such as Westmoreland. In nice antique condition consistent with age and use, showing minor air bubbles and light surface wear typical of early pressed glass. A fine and collectible piece of 19th-century American lighting, equally at home in a period interior or displayed as part of a curated antique glass collection. 9.5h x 4w x 4d
