Frosted and clear pressed glass lamp base

This object appears to be a vintage electric lamp base or converted kerosene lamp stand, featuring a combination of frosted and clear pressed glass elements. The stem is primarily composed of a frosted glass column with architectural ribbing and faceted bulbous sections, connected to a wide, scalloped circular base. At the top of the stem sits a weathered brass or gold-toned metal collar which connects to a clear pressed glass font or bowl-shaped shade holder. The clear glass portion exhibits a deeply patterned scalloped or thumbprint-style texture. Stylistically, the piece is consistent with American or European glassware from the late 19th to early 20th centuries, such as the EAPG (Early American Pattern Glass) era. No maker's marks or signatures are visible in the image to provide a firm attribution to a specific manufacturer like Fenton or Fostoria. Condition-wise, the frosted glass shows surface grime and possible minor staining around the bottom edge, while the metal fitting displays significant patina and oxidation. The item’s age is estimated based on the mold-formed pattern and mounting hardware, though it lacks verification from a physical inspection.

Based on the provided image, I have examined this lamp base, which displays characteristics typical of late 19th or early 20th-century pressed glass. The combination of a frosted architectural stem and a clear patterned font suggests a design common during the Early American Pattern Glass (EAPG) era. Based on what I can see, the item appears to be a composite piece, possibly converted from kerosene to electric use, though I cannot verify the internal wiring or the stability of the metal collars from a photo. The value is estimated at the assumed identification as a vintage period piece. If it were found to be a mid-century reproduction or a modern 'in the style of' piece, the value would likely decrease to the $15–$25 range. The current estimate reflects the significant oxidation on the metal fittings and visible surface grime on the frosted glass, which suggests it has not been recently restored. Market demand for unattributed EAPG-style lighting remains steady among collectors of Victorian-era decor, though the lack of a visible maker's mark like those of Fostoria or Fenton limits the premium. To confirm the origin and age, a physical inspection is required to check for mold seams, glass clarity (under UV light), and the specific threading of the collar. Documentation of provenance or a hallmark on the underside of the brass fitting would also be necessary to solidify this hypothesis. Without such verification, this estimate remains a working baseline for a decorative object of this age and condition.
