On June 30, 1857, James Oliver filed a patent application for chilling the wear face of cast-iron moldboard plows.  While pouring molten cast iron in sand molds he circulated hot water through chillers to regulate the rate of cooling. Oliver's control of raw material content and cooling produced moldboards with a very hard surface  and a softer, tough inner core for strength.  Their fine textured wearing faces of uniform hardness maintained a mirror polish and resisted rust.
