Magma should really be made hotter seeing we can use it to melt iron

Who said we were melting it? In forges, we only need to get it hot enough to make it malleable. At smelters it only needs to be hot enough to burn out impurities.

I've always assumed that magma was the dwarf's niche magic, similar to how elves can make (crappy) wooden armor and harvest wood without killing trees. Seems reasonable, seeing as a few of the metals we work (notably steel) don't melt at magma temperatures and are barely workable at a mere 1400 degrees.

wasn't a lot of this done with the molten rocks mod already? or is this to collect references to compliment that?
Wow! The molten rocks guys have done good work. I'll run through their lists and sources and try to add them to the list. It look pretty comprehensive. I would say all we can do is complement. Actually, maybe we should move this discussion over there for now. I feel like kind of a fool for starting a new thread on this when there's been so much work done on this already.

It look like they haven't got a gems section up though, so I think something can still add something to the discussion over there.

assuming gabbro = basalt then: Gabbro Basalt melts at about 984° to 1260°

http://www.minsocam.org/MSA/collectors_corner/arc/tempmagmas.htm

also from there: granite at about 1215° to 1260°

I'm not sure where you get the idea that gabbro and basalt are the same thing.

For constructions, the melting point doesn't mean squat. Lots of materials become maleable or at least lose their rigidity long before they melt. Even though steel can survive well over 1000 Celcius, you wouldn't want to operate it at temperatures close to that, because it's just not going to be the hard material you're used to.

It's just crystal size that's different for most of it, isn't it?

according the wiki it is. of course that info does come from wiki, bo for a game it can be considers a reliable enough source.

Quote from: Wikipedia
Gabbro (pronounced /ˈɡębroʊ/) refers to a large group of dark, coarse-grained, intrusive mafic igneous rocks chemically equivalent to basalt. The rocks are plutonic, formed when molten magma is trapped beneath the Earth's surface and cools into a crystalline mass.
