2003-9-2 · Now pure iron has a very high melting point, about 1530 degrees. So when the newly-formed mass of iron coalesces at 700 degrees, it remains a red-hot, slightly plastic solid called a bloom. The smith can hammer on this hot mass to shape it (and to make it extrude lumps of impurities that it might otherwise congeal around).
