"Great buildings, like great mountains, are the work of centuries"
Victor Hugo
Last week's blog introduced you to Roman ceramic building materials (CBM), so today let's discover the science behind the study!
How and why is Roman CBM studied by archaeologists?
Archaeologists use a range of traditional and cutting-edge
analytical techniques to study bricks and tiles. These range from
morphology-based examinations, that is looking at their shape and function, to
fabric analyses, which basically look at the recipes of clay and temper (an
extra material added to clay to change its working or firing properties) used
to make the artefacts.

Expensive scientific compositional techniques such as
portable x-ray fluorescence, which gives an elemental profile for the object,
are also occasionally used. These analyses often aim to source the brick or
tile, seeking to work out where the object was made and how far it was
transported. This is done in order to understand the scale of production and
infrastructure in place for building materials across the Roman world.
What relevance does Roman CBM have to our society?
While Roman brick and tile might seem like a dry and dusty
subject (which the objects quite literally are!), my own PhD research at
Bournemouth University on the Roman Baths is hoping to ask questions that make
these materials relevant to how we understand our world.

CBM was introduced
into Britain by the Romans around the time of the Roman Conquest of Britain in
43 AD. The native people never used it and never produced
it, and subsequently Roman brick and tile industries and workers have been
assumed to be entirely imported from the continent. My research is hoping to
check this assumption, exploring if there is evidence for the incorporation of
local potters or other individuals into these industries. In this way, I will
be exploring the role that the production and use of CBM played in the
development of Romano-British identities. I aim to contribute to our
understanding of how people thought of themselves and how they identified,
whether native, Roman or somewhere in between, in this important period of
British history.
At a time where so many
different British identities intersect, acknowledging and working to understand the
complex role of identities in Britain’s past can also help us to understand our
own contemporary society.
Thank you very much for reading, I hope this post has inspired you to look on humble
brick and tile with a new light!
