Cementation process is a common technique for producing steel through the carburization of iron. Unlike recent maintaining methods, it enhanced the quantity of carbon within the iron. It was mainly maintained before the 17th century. The only example of a good Cementation Oven in the United Kingdom is the one in Sheffield. It was invented by Johann Nussbaum, who started this job at Nuremberg in 1601. The operation was patented in England through William Elliot and Mathias Meysey in 1614. Within this period, the "invention" was the base of a new industry or a new production line, and the patent was shortly transferred to Sir Basil Brooke. A paragraph in the patent document preventing the import of this metal was declared to be rejected as he wasn't able to provide as much good produced metal as was demanded. Considering the thickness iron bars, the pots get heated from below for approximately a week, or even more. Bars get examined subsequently and once the desired condition was reached the heat starts the withdrawn and the pots were left till they cool, this operation consumes for almost two weeks. The iron gains a 1% weight in mass caused by the added Carbon during the charcoal process, and results in heterogeneous bars of Blister Steel.
Later in time the iron bars get shortened, bound, heated and hammered then pressed or rolled to eventually become Shear Steel. Another thing could happen bars get broken up and melted inside a crucible through a crucible furnace and produce crucible or cast steel.
