BoroGlow Secret White Glow In The Dark Glass Tube - UV Reactive Sky Blue Glow
Secret White with Sky Blue Glow - An opalescent milky white borosilicate glass tube that glows blue in the dark and under UV light.
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.
