| May 6, 2015 at 11:04 | comment | added | Adam White | @dennis97519 I believe zinc is unique in having this property, and I was able to find the correct term for it, 'spangle'. Zinc exhibits visible spangle. Other metals will exhibit spangle, but they are likely too small to see. Two examples would be silicon electrical steel, which predictably has silicon in it, and something called malleable iron. Malleable iron has a low carbon content. Its something about the annealing process that cause the carbon to aggregate into tiny spheres of graphite. | |

Found a grammar mistake, tried to clarify a point i was trying to make, reworked one sentence for a cleaner, more concise statement.
