Antique Uranium Carnival Glass Grapevine Compote 7.75

A museum-quality antique carnival glass compote in a saturated teal/peacock blue iridescence, richly molded with an allover grapevine and leaf motif and finished with a graceful scalloped rim and elegant pedestal stem. Under blacklight, the glass exhibits a strong uranium-glass response (green fluorescence), confirming a uranium-bearing batch—an elevated collecting category beyond standard carnival alone. Material: Uranium Glass + Carnival Iridescence (two different things) • Carnival glass refers to the iridescent surface—a metallic-salt treatment applied while the glass is hot, then reheated to “strike” the rainbow sheen. • Uranium glass refers to the glass formula itself (uranium oxide in the melt), producing the characteristic UV/blacklight glow. This piece shows both: true struck iridescence and blacklight-reactive uranium glass. Manufacture: Pressed in a Multipart Mold (documented in photos) This compote was pressed in a multipart mold, then finished and iridized. The radial panel ridging and mold partition geometry visible at the base and in your macro details are classic pressed-glass indicators. The close-ups also show fine hairline mold/press striations (“hayline” marks)—manufacturing characteristics valued by collectors because they read as authentic period production rather than later, overly “perfect” reissues. (Collector note: these hairline/hayline marks are manufacturing evidence—not cracks, not chips, not repairs.) Not Indiana Glass (addressing prior buyer confusion) This is not Indiana Glass. Indiana Glass is a later 20th-century American mass producer commonly associated with cleaner, standardized industrial mold output and widely reproduced patterns. In contrast, this example shows period pressed-glass mold evidence (radial base ridging, mold partitioning, and fine press striations) consistent with earlier carnival-era production. It is offered as an unmarked, antique pressed carnival glass compote, not an Indiana attribution. Condition Immaculate, collector-grade condition. No chips, no cracks, no repairs observed. Iridescent finish presents with excellent clarity and strong color play. Measurements • Mouth diameter: 6 3/4 in (6.75”) • Height: 7 3/4 in (7.75”) Marks Unmarked as produced. Unmarked bases are common for antique carnival-era pressed glass; many examples originally carried paper labels that did not survive. Estimated age & origin (best-practice attribution language) Estimated: early 20th century (circa 1910s–1930s). Likely North American production based on carnival-era pressed-glass tradition and grapevine patterning.
