NS-152 Galaxy is the first collaborative effort between Northstar Glass & Trautman Art Glass to produce a new color in rod. This color was formulated from the iconic NS-125 Jet Black base along with the amazing sparkle from the TAG Stardust family. Very durable & easy to use with a beautiful balance of dense black and heavy sparkle. Safe for encasement, though not recommended for millefiori or deep encasement. Use an oxidizing flame to prevent any gray streaks caused from reductive environment.
