Butterley Company, Ripley, Derbyshire, SK 399 517
Date
The Butterley Company was established in 1790. Puddling ceased in Britain in 1976 (although possibly much earlier on this site).
Description
Ball Slag?
Discussion
A dense tapped? slag presumably produced during balling, i.e. consolidating a bloom of iron in a puddling furnace. Is this the same as cinder tap? The company provided the iron for the construction of many major buildings in Britain, such as St Pancras railway station.
