I'm new here, I did a quick search but couldn't find anything related to this. Sorry if it's already been discussed. But anyway, I'm running the newest version, 40d, and I was wondering if this was a bug or an intended feature of the game.
I am on a map that has plenty of flux (dolomite if it matters) and iron (hematite). Early on I had no problem making tons of steel stuff through charcoal fuel. I found a magma pipe and now have lots of magma forges and smelters. However, my magma smelters still require 1 unit of fuel (charcoal in this case) to make pig iron, and 1 to make steel. What I mean is, if I have no coal in my fortress and I go to the smelters I do not have the option to make pig iron or steel. If I create some charcoal from wood at a wood furnace I then have the option to make pig iron and steel.
Is this working as intended? I figured that magma would solve all my fuel needs, but as it stands now I still need fuel of some kind to keep a steel economy going. I thought magma was supposed to replace other forms of fuel. Keep in mind that I am positive my magma smelters and forges are correctly placed, because I can make non-steel materials for no fuel cost to my hears desire as long as I have the components.
Any idea what is going on? Am I doing something wrong? Did I just miss how this is supposed to work? Thanks for any help.
