In 2010 an archaeological evaluation was undertaken by Channel 4’s Time Team at Derwentcote, County Durham, the site of one of the best examples of how the ferrous metal industry evolved in Britain during the Industrial Revolution and now a Scheduled Ancient Monument. The results of the evaluation, along with analysis of the crucibles and metallic residues, are of significance in providing information on the 19th-century crucible steel operation at Derwentcote, the first such installation to have been excavated outside Sheffield
