Coaster - Uranium glass glaze

Decorative glass coaster of uranium glass with a pronounced crackle texture in a clear yellow-green tint. Under UV light the glass emits an intense, bright green fluorescence, with the internal fracture lines and air bubbles strongly accentuated. The craquelure pattern is deep and powerfully present, creating a layered, almost crystalline effect with clear depth. The top side is smoothly finished, while the interior shows a dense network of glass fragments that, in both daylight and blacklight, creates a lively play of light. The object is signed and most likely originates from the Czech Republic, which fits with traditional Bohemian glass production where uranium glass and controlled crackle techniques were more commonly used. Due to its low, rounded shape it is primarily suitable as a coaster, but it can also function as a compact collectible within a uranium glass or studio glass collection. Despite its modest size, it is visually very powerful, especially when used with UV lighting where the fluorescence becomes evenly and intensely visible.
