AI Item Analysis

·AI can make mistakes·Verify before acting
This item is a classic carnival glass swung vase, characterized by its vibrant marigold iridescent finish. The piece features a traditional trumpet shape that flares significantly at the pedestal base and tapers toward the middle before expanding into a dramatic, multi-pointed ruffled rim. The iridescence displays a spectrum of metallic hues, primarily golden-orange with strong flashes of pink, magenta, and soft violet when light hits the surface. The construction is pressed glass, as evidenced by the vertical mold lines running down the body and the petal-like geometric pattern embossed on the base. The 'swung' technique is evident in the elongated, slightly asymmetrical profile that was achieved by swinging the glass while molten to stretch the neck and rim. It likely dates to the early 20th century (circa 1910-1930), a style popularized by manufacturers like Fenton, Northwood, or Imperial. The condition appears very good with no visible chips or cracks. The surface retains a high-gloss luster, though there is a faint circular wear mark at the very bottom edge of the base, typical of age and shelf contact. The glass exhibits good clarity in the non-iridized portions, and the color application is consistent throughout the body, reflecting high-quality American glassmaking during the Arts and Crafts or Art Deco transition period.

AI Appraisal Report

I have examined this Marigold Iridescent Swung Glass Vase, a hallmark of American Carnival Glass production from the early 20th century. My visual inspection confirms the 'swung' technique, created when a glassworker swung the molten vessel from a mold to elongate the neck, resulting in the unique, asymmetrical ruffled rim characteristic of makers like Fenton or Imperial. The marigold iridescence remains vibrant, showing the desired 'oil slick' flashes of magenta and violet. The 'target' or 'petal' base pattern suggests a common but popular production line. The condition appears excellent, with the high-gloss luster well-preserved. Minor shelf wear on the base is consistent with age and does not detract from the value. Market conditions for standard marigold carnival glass have stabilized; while no longer at their 1990s peak, these pieces remain staple collectibles. This specific height and color are relatively common, which keeps the price point accessible compared to rarer 'electric blue' or 'amethyst' variants. Limitations: My assessment is based on digital images. Without physical inspection, I cannot rule out 'flea bites' along the interior rim or micro-fractures in the base. Full authentication would require verifying the presence of a maker’s mark (often found at the interior center base) and feeling the texture of the iridescence to ensure it is not a modern 'flash' coating. To increase provenance, research into the specific mold pattern name via a standard reference guide (such as Edwards & Carwile) is recommended to pinpoint the manufacturer.
