Experiment #46 Solaria Translucent is a cadmium based CFL reactive glass that shifts from yellow to orange. This variation Solaria is a more translucent golden yellow color and now available in tubing for a limited time. With Northstar’s experimental hand pulled tubing, you should expect the same quality as our standard tubing product line. This is an exclusive product available through Northstar only. For best results, work on a neutral to oxidizing flame & let the heat sink in to prevent boiling.
