The selected item is a luminous glass vase, a decorative piece designed to glow in low-light or dark environments. These vases are typically handcrafted using a combination of hand-blown glass and integrated luminous materials, such as luminous stones or powders, that absorb light during the day and emit a soft, starry glow at night. Dimensions: Common sizes include heights of approximately 25 cm to 30 cm, with a diameter around 10 cm to 12 cm. Direct Light is Best: Unfiltered, direct sunlight is the most powerful charging source. Placing it where it catches the afternoon sun (like a west-facing window) is ideal for an all-night glow. Duration of Glow: Once fully charged, these vases typically emit light for about 3 hours, gradually softening over time.
