Originally posted by vivifySteam is water vapour, so no. But if you heat any substance enough then, in the absence of an oxidising agent it will become a vapour. On this planet there is lots of free oxygen so anything that can be oxidised, like a metal, will tend to burn rather than become a vapour. Things that can't oxidise like carbon dioxide will form a vapour. Magma is a little tricky, I'm not sure what will happen in the absence of oxygen, but it should be noted that in the fairly extreme temperatures needed to vaporise it it could undergo chemical changes, so you might not get "magma vapour".
Can liquids which aren't water turn into steam? For example, can magma ever become steam, if exposed to a hot enough temperature? Or what about liquid metal?

Originally posted by sonhouseMagma is typically not hot enough for all (or even most) of it to vaporise. Magma is a complex mix of chemicals and some of it does vaporise and / or oxidise (burn). That is what causes volcanic eruptions.
