Hammerscale Sampling

Hammerscale sampling has been resumed this year. We are taking samples from 20cm squares across the entirety of Trench 3 in order to build a picture of where metal-working may have been undertaken during the 9th century. This is a long-process but will potentially wield extremely useful results such as the site of the forge.

The individual samples taken from the trench are bagged and labelled so a trench plan can be built of areas of metal-working

A preliminary examination of the hammerscale by David Sim identified magnetic residue in the samples.

Once examined under a digital microscope he found there was hammerscale and a small amount of spheres. These spheres are indicative of high-temperature forging.


The thinking on site is that this area may have been used for re-cycling metal and possibly re-forging iron. However, a more extensive investigation is required before these ideas can be built upon.
