Northstar Cadmium Blood Red (EXP70) - Simax Encased WonderTube Tube Second Quality Exp 70 Cadmium Blood Red

Exp. #70 Cadmium Blood Red is a dense, saturated dark red with a glossy surface that holds its tone whether you run it thin or thick — no washing out, no drifting toward brown in the flame. Here it comes encased in Simax as a WonderTube, so you get that red as a working tube for vac-stacks, line work and blown sections. It is a cadmium glass: let the heat sink in rather than driving it hard, or it will boil. Second quality means heavier cosmetic flaws, bubbles or striations than first — fine where the surface is reworked, encased or cut into.
