Nitor (Thaumcraft 1)

(infusion mold + glowstone dust)
Like coal, glowstone dust can be infused multiple times, turning it into increasingly potent Nitor. Oddly enough, more vis can be extracted from Nitor in a crucible than it cost to infuse in the first place. There must be some way to make a profit out of this odd feature.
