“…Given the ubiquitous association of iron seepages and encrustations with 'red' burns, it is unlikely that access to these resources would have been wholly restricted to rural communities (although access to woodland and hence charcoal might have been restricted, the towns relying more heavily on peat and coal) and although no bloomery furnaces have yet come to light in Perth, this in itself is not absolute evidence that they did not exist in the town. Admittedly, where excavation has recorded structures in association with industrial waste, those structures are thought to have related to smithing of iron, rather than its production (eg Meal Vennel: Cox 1996). However, the combined area of excavations to date in Perth is a small proportion of the total area of the medieval town.…”
