622031 TAG Blue Stardust Borosilicate Glass Rods. 

This is a transparent aventurine sapphire blue with big, glittery dichro-like sparkles. Great for layering. The usual cautions against long, hot garaging technically apply since this is an aventurine color, however it is stable in implosions, encasements, and virtually any application.

 Size: Diameter 5-7mm, length 19-20", weight per rod .08 lb, approximately 12-15 rods per pound. There is a quarter pound minimum per color. All TAG rods are first quality.
