What I'm told will be observable is a difference in the rate of cooling. I guess the science is that the iron beneath the stamp has been altered (density maybe?) as a result of the original stamping and will therefore cool at a rate different from that of the surrounding iron. He actually thinks he may be able to discern a newer stamp from an older one. We're going to do some experiments and I will post results. Initial meeting Thursday.
