This is an antique glass kerosene finger lamp, characteristic of late 19th to early 20th-century domestic lighting in the United States. The lamp is constructed in three main parts: a pressed glass base and font, a metal burner, and a blown glass chimney. The pedestal base features a paneled octagonal design with an integrated glass finger loop handle for portability. Above the base is a rounded, clear glass reservoir (font) which contains a white textile wick. The metal burner assembly includes a thumbwheel for adjusting the wick height; however, any maker marks on the wheel are not legible from the provided image. The lamp is topped with a tall, bulbous blown glass chimney that exhibits a distinctive smoky-grey or light amethyst tint.
