Antique French Opaline Glass Pitcher – Sky Blue, Handblown with Polished Pontil,

Antique French Opaline Glass Pitcher – Sky Blue, Handblown with Polished Pontil, Manganese UV Reactive, c.1900–1920 This charming handblown French opaline glass pitcher showcases a soft sky-blue opaline hue with a silky semi-translucent glow that gently diffuses light through the glass. Under a 365 nm UV blacklight, it emits a vivid green fluorescence from manganese content — an element widely used in early 20th-century glassmaking as a clarifier and color stabilizer, long before uranium was common in decorative glass. The piece likely originates from France, consistent with work by Portieux-Vallerysthal or Baccarat, both known for fine opaline tablewares and vanity pieces produced during the early 1900s. It features a graceful baluster form, applied handle, and a polished pontil mark on the base — all signatures of true hand-finished craftsmanship. ⸻ ✨ Details • Color: Sky Blue (Bleu Opalin) • Material: Handblown opaline glass • Glow: Bright green fluorescence under 365 nm UV from manganese content • Dimensions: 4.25” H × 5” W (spout to handle) • Base: Polished pontil mark • Condition: Excellent vintage condition – no chips, cracks, or repairs.
