Copperas House a small post-medieval industrial site which is now reused as a residence. Produced ferrous sulphate from the mudstone which was mined between the seams of gannister and coal. This was mostly used in the production of mordant for fixing dyes to cloth. This site had good access to Flash House Colliery which opened in 1870 until 1898 (Gill 2007b). Built on an area of early enclosure dating to the early medieval period. There is fragmentary legibility of the enclosed landscape as the external boundaries of the industrial site follow on from larger enclosures. The origin of the former moorland landscape is uncertain though this area is likely to be moorland by the Roman period (see Bevan 2003 for discussion of environmental evidence in region).
