The final phase of the hammerscale sampling is in progress in Trench 3. Hammerscale is the waste product created when forging metal. In Trench 3 we believe we have a 9-10th century metal-working area based on a temporary structure. The area is rich in metal objects, most of which are damaged, which has led us to believe that the forge may have been used for the re-cycling of metal. The following video explores how we undertake hammerscale sampling in order to map its distribution and the implications this may have for our interpretation of the site.
