re: Anyone seen NOAH

First person named working brass and iron' Tubalcain; this is before the flood There is an iron hammer found in porous coal that is made of 96.6 % iron, 2.6 % chlorine, and 0.74 sulphur.

The relatively high concentration of chlorine combined with a total absence of carbon, which would cause corrosion by reacting with oxygen..ie it don't rust.
