Cementation was an early technique to produce blister steel by heating wrought iron in sealed pots in a coal fired furnace. This was replaced by crucible steel and then by the Bessemer process and later techniques. This was in Daniel Doncaster's works in Sheffield and is now in the car park of the HSBC office complex on Hoyle street. It is claimed (Cossons - The BP Book of Industrial Archaeology) to be the only complete example left.
