Fusing together redstone dust and glowstone dust results in Nitor, a seemingly eternal and sourceless flame.
It also has an additional strange property - it seems to contain more Vis than went into its creation. Maybe there is a way to harness that?
Nitor is crafted by infusing Redstone Dust with Glowstone Dust:
It can be placed in the world as an everlasting light source, where it appears as a hovering red flame. It provides the same degree of illumination as a regular torch and like torches, it can be effortlessly placed and removed. It can also be placed underwater to create an air pocket.
