Iron and Steel

In his original experiments he had fortunately used uncontaminated iron As a result he set up his own steel works in Sheffield but persuaded his suppliers to ensure the purity of the feedstock The problem with the phosphorus containing ores was solved by changing the lining of the furnace the chemistry of which caused the phosphorus to be removed from the steel in the slag
