Ten pieces of iron slag, probably of Roman date based on finds made in the vicinity, but an Iron Age to medieval date range is given. The pieces range in size from very small (L.: 14.8mm) to 52.5mm long. Some are light (weight), dark in colour and bubbly suggestive of high temperatures reached. However, there is insufficient material to say whether this is industrial or simply from a domestic fire.

The object is a piece of slag of uncertain date. More specifically, this object is tap slag; it was formed during the smelting process when it became necessary to empty the furnace to keep the channels clear. This slag was removed by tapping the furnace, causing it to run out from a hole at the base of the furnace while it was hot. This forms the characteristic ropey-looking surface. The material is dark grey and dense. There are inclusions showing iron corrosion in the base of the object. Though it is not possible to date this object, it was recorded due its proximity to Dere St…
