CERAMIC BUILDING MATERIALS ASSESSMENT REPORT
S Garside-Neville
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.
Only one
fragment of roof tile could be identified as Peg tile, this came from [2007].
