This is an often found feature in North Devon, especially in the Brayford area (Roman iron tap slags and smithing wastes) and in Combe Martin (late medieval/early post medieval silver/lead slags).
These materials were found to be extremely hard wearing as road foundations and the large scale of both iron and lead smelting, and smithing of the former provided an almost never ending supply..
