Pink Proton is a UV reactive (UVR) color that glows a bright coral pink when hit with a UV light. In sunlight this color is a transparent and slightly off clear, while UV wavelengths light the glass up like a pink neon sign. Pink Proton is slightly stiff, easy to work in the flame, and highly stable and compatible with other colors. This color looks great as the feature on a piece, or as a flashy accent for other colors. Pink Proton is available in rod and tube, with equally strong UV reactions in each form.
