Netherrack dust and tar are used as consumables in production of jet fuel, used to run Gas Turbine, Microturbine and Pulse Jet Furnace.

Rotarycraft Handbook DescriptionEdit

"Netherrack dust is made from grinding netherrack blocks in the grinder, while tar is made by grinding soul sand. Both of these are required constituents of jet fuel due to their hydrocarbon content."
