What is the lava thing for in the industrial centrifuge
In the gui for the industrial centrifuge there is a lava area.
what is it used for? Can I speed up the machine this way?
It is used to feed lava from a container object like a bucket.
By default you get:
16 Still Lava → 1 Tin Ingot + 4 Electrum Nugget + 2 Copper Ingot + 1 Tiny Pile of Tungsten Dust
This might be different depending on the pack.
