This might be indicated by the color of your reticle (the little crosshair cursor thingy). So you get a feel for what shade of orange it should be before you pull it out or whatever. Pull it out too soon or too late and you've messed up the temper of the metal and may have to go back to a previous point in the process
Here's a link on the subject:
http://www.lostcrafts.com/Farm/Blacksmithing-15.htmlTo temper a piece of steel (I know this from books, not experience), there's two steps:
1. You heat the metal to red or orange, and then plunge it into water. The sudden change of temperature makes the molecules 'freeze' and scrunch up together. This leaves the steel in about its hardest state, much too hard to use.
2. You heat the steel again, but much less. to tell how hot it is, you can polish a bit of it to get the outer coating off. On that spot you will see colors from straw colored, to yellow, brown, purple, blue, and then green. Then you quench it again.
Higher temperatures will result in a softer steel. The amount of carbon in the steel determines how much you want to heat it before quenching, and the use of the tool determines how soft you want it. (softer is better for hammers, harder is better for files, etc. (there are two scales, basically, hard/soft, and tough/brittle))
or melt it all down and start over. For example, if you were a really good black smith then you might be able to put a few swords in the fire at once and just keep track of their temperature from time to time to pull them out when appropriate.
I don't think you melt steel, as it will burn, and so you don't use molds for steel. (less sure on this one)
Hunting is not plentiful (say because the woods is overhunted or because someone burned down most of it) and the wolves start to venture out onto the roads looking for a meal or maybe even heading into to town to steal a chicken or two if they are really hungry.
psshh, who would burn down a forest...
