As effective as it is at enabling white light, however, mercury—sometimes called quicksilver—is also highly toxic. If cut with fluorescent lamp glass, any phosphor that goes in the wound is likely to stop blood clotting and can interfere with curing. That vapor produces a short-wave ultraviolet light that causes the phosphor coating that lines the inside of the tube to glow.
