Arc Furnace
T1
This furnace has a cooling system to safely reach higher operating temperatures. This provides increased throughput and an opportunity to reuse some of the excess heat. Power requirements are increased as well.

An Arc Furnace is a machine used to convert Quartz into Molten Silicon for the later creation of Silicon (Poly) in a Silicon Reactor. It requires Coal and Graphite while producing Slag and Exhaust byproducts. As Silicon (Poly) is a strict requirement for Electronics, the Arc Furnace or its Arc Furnace II variant is necessary for its production.
