Now here's a question I am JUST NOT GETTING!
I have been learning about different compositions, for different uses, needing different treatment. The total composition listed in the charts does not eaqual anywhere near 100%. Whats the rest?? Is it just iron, is there a given wt % of unkowns, or have I missed something basic and simple?
