Uralin is a glass enriched with uranium, which gives it a specific color (green to fluorescent yellow through blue) and which makes it react to ultraviolet light (under a hotsell UV lamp the uraline becomes very phosphorescent). Also called uranium glass or Vaseline glass by the Anglo-Saxons, this very rare glass was used at the end of the 19th century until the Art Deco movement and then practically disappeared because all uranium stocks were then requisitioned by governments for military or scientific applications.
Old object (20s or 30s) in very good condition for its age, no crack or splinter in the glass, some traces of minimal use (micro-scratches), manufacturing irregularities (lines in the glass, small bubbles, traces of mold) that testify to the ancient manufacture of this cup.
