CERAMIC BUILDING MATERIALS ASSESSMENT REPORT

S Garside-Neville

ROMAN

Roman material made up the bulk of the sample.  Forms retrieved included: imbrex and tegula (roof tile), brick (used for a variety of building purposes) and box flue (used in the hypocaust heating system).  There were examples of plain white plaster and daub from [2001].  Although there were a few examples of mortar along broken edges (mainly on bricks), which often indicates reuse, there was not enough to suggest that this sample had been robbed and reused in another building.  The box flue fragments consisted mostly of plain faces, many of which indicated that the form had a square, knife cut vent.  There were only 2 examples of keying for the box flue (from contexts [2001] and [2043]), and they were both combing, which is thought to be introduced in the early 2nd century. 

Two tile stamps were found - one from [2020] matched with Betts's catalogue number 46, and is a sixth legion stamp, the other from [2024] is currently unidentified.  There was a possible voussoir (used in forming arches) from [2047], though this may just be a badly formed brick.  A single fragment of vaulting tube (used for forming roof vaults) was present in [2024]. 

There was a scatter of sandstone flags throughout the sample.  None of the examples had a nail-hole, so cannot be identified as roof tile.

MEDIEVAL

Only one fragment of roof tile could be identified as Peg tile, this came from [2007].
