Bog iron is a type of iron ore composed of mostly mineral goethite and other iron-bearing minerals with impurities like clay or plant debris. Bog iron used to be a very important ore of iron before better alternatives like banded iron formations were discovered.
There are different common types of cast iron. Gray cast iron is negligible ductile, brittle, and dampens vibrations. In gray cast iron the carbon has the form of graphite flakes.White cast iron is hard, wear resistant, and brittle. Here the carbon is bound in small very hard ceramic particles called cementite.
