Description

Used to smelt ingots and alloys using an oxygen/volatile gas mix. Ice (Oxite) and Ice (Volatiles) can be manually input directly in the furnace in order to create crude gas mixtures, or to be directly extracted as an easy trick for melting the ice.

Recipes

While smelting steel is easily achieved with ice, other recipes usually require a working piping setup. This can be done by separating gases into tanks using atmospheric units and piping individual gases through a mixer and a Pressure Regulator or a Pipe Volume Pump connected to the furnace input. Output should also be extracted and vented/recycled through a backpressure regulator to keep furnace pressure in check. The optimal gas mix that burns completely is 1 part (33.3%) oxygen to 2 parts (66.6%) volatiles, other mixes would also work but leave you with leftover oxygen or volatiles depending on the percentages used. It could also result in lower temperature if that is desired, but you could also use a volume pump with a lower fuel input setting.
