Overview TAG Blu-V is a Trautman Art Glass borosilicate color that looks nearly clear in normal light, with a faint blue cast, then fluoresces a bright blue under UV. It’s a versatile “effect clear” that can be worked as a clean base, used for subtle tint, or pulled into stringer for UV-reactive linework that stays crisp and readable. Why this color Blu-V is popular because it gives you a strong UV payoff without looking heavily colored in everyday lighting, so it layers cleanly into modern, high-contrast designs. It also plays well as an accent over clear or darker colors, letting you add hidden detail that only shows up when the piece hits blacklight. Best uses UV-reactive accents, dots, and linework that glow blue under blacklight Clean bases and overlays where you want a near-clear look with a subtle tint Stringer work for crisp detail on beads, pendants, and small components Layering with other UV colors for contrast and multi-reactive effects Related items TAG Pink Proton Rod TAG Blue Slyme Rod TAG Blue Blizzard Rod
