Machina, the "machine" aspect, is composed of Instrumentum and Motus, with no compounds of its own. It is found in redstone and in various devices, notably both wood and stone buttons. While a number of crafting recipes require it, it is also used as an indirect source of Ordo: 16 logs produce a stack of wooden buttons (and for that matter, redstone dust can become plentiful in the later game), and when Machina is double-centrifuged, it yields 50% Ordo.
