This "Wine Glass with Spiral Leaf Motif (Goblet)" by Émile Gallé is one of the early, valuable works of Gallé, a leading glass artist of the Art Nouveau movement. Early enamel and gold-painted glass works were likely produced by Gallé himself, and this is a special piece with Gallé's early signature. Technique: Uranium glass, mold-blown, gold decoration Features: Uranium glass is glass mixed with uranium as a colorant. It appears pale yellow-green (emerald green) in natural light and exhibits a blue-green fluorescence under ultraviolet light (black light). Design: The thinly blown body features a spiral leaf pattern created by mold-blowing, and the rim is decorated with gold. Production Year: Circa 1900 ~Other~ Carefully packaged.
