* Can it be done with no atmosphere?
* What happens to vapours is there is no atmosphere?
* Mars is cold. Would making a heated bunker be enough? Thermal Insulation?
* If there is no atmosphere, where does the heat go?

Iron will not corrode readily because Mars' thin atmosphere has virtually no free oxygen.

Need furnace that can withstand the temperatures. Probably could just be made from bricks, concrete (or even rocks). See [https://en.wikipedia.org/wiki/Puddling_(metallurgy) Puddling]

Ceramics, concrete and such for insulation.

Ladles are the things used to transfer molten metal.

Need Crucibles. [https://www.youtube.com/watch?v=HuM4xSNX0no A formula for graphite]. Steel ones don't last more than a half dozen goes.
