Cobalt blue pressed glass kerosene oil lamp with brass burner, American EAPG (Early American Pattern Glass)

This kerosene lamp represents American lighting technology from the late 19th to early 20th century, when pressed glass oil lamps were common household items before widespread electrification. The cobalt blue color was achieved by adding cobalt oxide to the glass mixture, making these lamps more decorative and desirable than clear glass versions. The pressed glass pattern and pedestal base design are characteristic of the EAPG period, when American glassmakers produced affordable yet attractive household goods through industrial pressing techniques. Cobalt blue glass lamps are highly sought after by collectors of antique lighting, EAPG enthusiasts, and Americana decorative arts collectors. The rich blue color, combined with the lamp's functional design and historical significance as a pre-electric lighting source, makes it appealing to those who appreciate 19th-century American domestic life and craftsmanship. These lamps are valued both as display pieces and as tangible connections to the era when kerosene lighting illuminated American homes.
