Hand-blown art glass vase

This is a hand-blown art glass vase featuring a globular, spherical body with a gently rounded shoulder and a relatively small, circular top opening. The physical construction utilizes studio art glass techniques, displaying a complex layered pattern of colors. The upper portion of the vessel is dominated by vibrant green swirls, speckles, and mottled white patches, punctuated by sweeping dark green linear bands that wrap dynamically around the spherical form. The lower half transitions into a warm amber and brown mottled pattern over a white background, creating a striking contrast. There is no visible maker's mark or signature discernable in the provided image, so the identification rests entirely on the visual characteristics of the glass body, shape, and color application. The overall style and technique are consistent with mid-to-late 20th century studio art glass production, suggesting a decorative piece meant for display. The surface exhibits a high-gloss finish with expected light reflections, and no major structural damage, cracks, or repairs are immediately apparent from the angle provided. The craftsmanship quality is evident in the smooth integration of the distinct color fields and the symmetrical, balanced blowing of the spherical form.

Based on what I can see in the photograph, this hand-blown art glass vase exhibits features consistent with mid-to-late 20th century studio art glass production. The spherical form, high-gloss finish, and complex layered color palette—featuring vibrant green swirls on the upper portion transitioning to amber and brown mottled patterns below—suggest skilled craftsmanship. However, I cannot verify from a photo whether there is an obscured maker's mark, signature, or pontil mark on the base, as none is visible in the provided image. My value estimate of $300-$500 assumes the attribution to a quality studio art glass piece of this period is correct. This valuation reflects current general market demand for decorative mid-century studio glass, where colorful, well-executed pieces attract steady interest from collectors of decorative arts. Physical inspection would be needed to confirm the exact weight, glass density, surface wear, and potential signatures. If an in-person examination reveals this piece to be an unmarked reproduction, a modern copy, or simply made in the style of mid-century studio glass without a notable maker, the market value would likely decrease significantly, dropping into the $75-$150 range. To establish a stronger attribution and potentially higher market value, an in-person expert appraisal and search for faint signatures or pontil characteristics would be necessary.
