Summary

 

A small amount of material was submitted for examination.  It consisted of slag, brick, probable roof tile, and daub.  Due to the small amount, it is difficult to comment on the dating with any great certainty.

 

Brick (Context 9)

This fragment is roughly made, overfired, and contains a large piece of ridge tile, presumably used as grog. There is a possibility that this brick was used for an industrial purpose, particularly as there is a forge on site.  It is probably post medieval.

 

Slag (Context 9)

The presence of slag is consistent with the presence of a forge on site.

 

Roof tile (Context 9)

There is a possibility that this tile is Roman.  The thickness, and the well-refined clay fabric does hint at this.  However, the sanding of the lower surface is not diagnostic in this case, so it may be post medieval tile made without the aid of a machine.

 

Daub (context 8)

There are two fragments of daub.  One fragment appears to show the imprint of wattles.  The fabric is typical of daub, being fairly friable.  Daub only survives if exposed to heat.  The date of the daub is difficult to determine, the daub of all ages being similar in format.
