A striking 19th century Napoleon III pendant lamp in blue and white opaline glass, richly mounted with gilt brass and bronze. The lamp features sculptural moulded opaline glass elements with pronounced lobed and fluted relief. The pale blue and milky white glass creates an elegant luminous effect when illuminated. The elaborate gilt metal mount is richly decorated with foliate ornament, beaded detailing and moulded decorative elements, complemented by a substantial upper canopy and suspension loop. The combination of blue and white opaline glass with richly ornamented gilt metalwork is characteristic of the French Napoleon III / Second Empire lighting tradition. The lamp is particularly impressive for its substantial scale and the quality and decorative character of its moulded glass and gilt metalwork. The exact manufacturer has not been identified and no maker’s mark is visible. Condition: Good antique condition with signs of age consistent with the period. The gilt brass and bronze show an attractive aged patina. The opaline glass appears well preserved, with no major cracks or losses visible in the supplied photographs. Electrical: The lamp has been electrified at a later date. The electrical wiring and components should be inspected and, if necessary, renewed by a qualified electrician before installation and use. Dimensions: 85 cm high × 33 cm diameter. A highly decorative and substantial example of Napoleon III opaline lighting, combining luminous blue and white glass with richly ornamented gilt metalwork.
