Experimental #21 Tubing

Experiment #21 was an older formula consisting of NS-137 Ill-uminati and a translucent white base. We have brought this experiment back for further testing with-in the formula. Northstar produced some hand pulled tubing as well as Experimental #21 Opaque rods. These Tubes are encased in simax to protect the raw color for workability as well as giving it a more transparent look. This glass is a transparent lime color with a bright green UV reactivity and luminesces best with a 365nm-395nm LED flashlight. This glass does contain uranium.
