roasting is a contamination of unwanted materials specially to iron .
when we keep some irons for long time we will sure see some substance which are cover by a layer not the iron.
we can control it by galvanisation or colouring or oiling the outer part of that materials like iron zinc etc.
I hope you will help in this
