So I have a metalsmith who's claimed a magma forge to make an artifact, but I can't figure out what he needs to begin construction. When I 'q'uery the magma forge he says he must have body parts, rock, silk cloth, pig iron bars, cut gems, and plant cloth. All of which seems like it should be available to him already. I slaughtered a bull just for him so there are cow bones available, I have a small stockpile containing turtle shells and a couple mussel shells already, I made 8 pig iron bars, I have bins and bins of rope reed fiber cloth, I have one or two bins of cave spider silk cloth I traded for, tons of cut gems of various types, and thousands of stone lying around. I have stone in both block and raw form.
If I use 't' to look inside the magma forge I can see several items already there listed as task items. He's already gathered a steel helmet, a single pig iron bars, a stray bull bone, and two topazolites. Is it possible he needs a specific type of stone or something? If I 'v'iew him and check his thoughts and preferences it says that he likes lignite, pig iron, tanzanite, and green glass. I have lignite but it's currently configured as an economic stone and it may also be the case that all the unused lignite is currently forbidden. I don't think I have any tanzanite. I do have raw green glass. Is it possible he needs unforbidden lignite or cut green glass? Can strange mood demands be that specific? Is there something else I might be missing?
