BoroGlow Guacamole Glow In The Dark Glass Tube - UV Reactive Green Glow

BoroGlow, the original maker of glow in the dark UV reactive borosilicate glass, 

Working tips:  Glow is susceptible to burning out. We recommend working in a cool flame, especially when doing terminations and connections. For best results we recommend using a very oxidizing flame, to the point where the oxygen is cooling the flame. Working far out in the flame is another great way to not overheat the glass.
