Product Details

Vintage Uranium Reactive Slag Glass Cullet Lot – Approx 2 lbs Total – Mixed Swirl Art Glass Chunks. Includes 3 substantial pieces measuring roughly 2–4 inches each. Beautiful creamy base with striking blue and red marbling, enhanced by a strong neon green fluorescence under 395nm UV light, indicating uranium content. These glow brightly and evenly, making them highly desirable for uranium glass collectors, display, or UV reactive décor. Solid glass (not plastic) with nice weight and smooth broken surfaces typical of vintage cullet. Great for display, paperweight use, terrarium décor (dry setups), rock tumbling, lapidary practice, or mosaic/art projects. Each piece has unique patterning—no two alike. Pre-owned condition with natural manufacturing marks, internal bubbles, and edge irregularities consistent with slag glass. No repairs or alterations. Sold as shown.
