Re: cold iron
Cold iron could be used as a more dignified label for pig iron, which is to say iron with a higher than 2% proportion of carbon (since less than 2% makes it steel.) After all it takes more heat to purify iron that much. One interesting possibility is to have "cold iron" be "iron that hasn't been melted for a very long time" Thus the way to deal with those pesky elves is to only use swords that are family heirlooms. Cold iron is old iron.
