Northstar Nemo (153) - Second Second Quality Standard Tube

Nemo is Northstar's gem-like aquamarine transparent - a bright, highly refractive blue-green that stays true where other copper blues go dull. It was formulated specifically to resist livering, the murky surface haze copper glass picks up in a reducing, propane-rich flame, and it runs flame stable and nearly air-free on the torch. This is second quality tubing: the glass chemistry is identical to first quality, but the tube carries heavier cosmetic flaws, bubbles or striations. Ideal where the surface gets reworked, cased or cut into anyway.
