Antique Glass Inkwell with Brass Lid

This is a small, portable antique desk accessory consisting of a clear glass reservoir and a domed metal lid with a brassy patina. The physical characteristics include a heavy, thick-walled square glass base featuring visible small air bubbles trapped within the material, which is consistent with older, traditional glass-molding techniques. The underside of the base shows a textured, diamond-patterned grid. Inside the square reservoir is an internal glass well insert designed to hold the ink and prevent spills. Capping the inkwell is a hinged or fitted round metal lid that displays a ribbed, fluted, or gadrooned design across its rounded top, showing moderate tarnish and surface wear consistent with age. There are no visible maker's marks, stamps, or signatures present on the exterior of the glass or the metal components from this viewing angle. The piece exhibits an overall vintage character appropriate for late 19th- or early 20th-century writing desks, though its exact origin and manufacturer remain unverified without physical inspection or internal markings. The identification is based purely on the object's form, materials, and internal well construction.

Based on what I can see in the provided image, this antique desk accessory appears to be an inkwell featuring a heavy, thick-walled square glass base with trapped air bubbles and a textured bottom, fitted with a ribbed metal lid. I can't verify from a photo whether the materials or construction are period-authentic, as modern reproductions can mimic traditional glass-molding techniques and aged patinas. A physical inspection would be needed to examine wear patterns, metal composition, and any hidden markings. Assuming the piece dates to the late 19th or early 20th century as suggested by its form, typical market demand for decorative vintage desk accessories of this type generally supports a value range of $75 to $150 among collectors of antique stationery. This estimate assumes the attribution is correct; however, value depends heavily on authentication. If physical examination reveals the item to be a modern reproduction, replica, or made 'in the style of' rather than a period piece, the value would likely decrease significantly, dropping to $20 to $40 as a decorative novelty. To confirm authenticity and exact age, an in-person examination by a qualified appraiser or specialist in antique glassware and desk wares would be required.
