Murano Cup Bullicante Neodymium Glass Alexandrite Barovier & Toso 1950

Important sculptural glass bowl made of Murano art glass, emblematic of Mid-Century production (circa 1950-1960) and attributed to the prestigious Barovier & Toso manufacture. The piece is distinguished by its fascinating Alexandrite hue (neodymium glass). This rare chemical composition gives it the dichroic property of changing color according to the light spectrum, oscillating from a delicate lavender purple under cold light to a bluish pink under warm light, creating a magical interaction with its environment. The thick wall contains a geometric network of air bubbles trapped in the mass: the historical technique of vetro bullicante. This demanding process requires creating regular cavities on a hot parison before covering it with glass to seal the air. The architecture of the piece was then shaped freehand (a mano libera). Under the action of the tongs, the master glassmaker stretched the edges to create deep asymmetrical waves with organic appearances. The base features a perfectly softened and flat pontil (molato). The condition is excellent: the material retains its shine, with no cracks. Minor usage scratches and a tiny micro-chip under the base attest to its age.
