Manufacture, wear and repair of the Chiseldon Iron Age cauldrons


Jamie Hood and Alexandra Baldwin, British Museum

With the Iron Age Chiseldon cauldrons excavated and cleaned to expose the metal surface we are beginning to see interesting technological features and evidence of manufacture revealing them to be sophisticated and high status objects.

Although they’re over 2,000 years old, different tool marks from shaping and thinning the copper alloy are preserved on the surface of the metal. These suggest the careful and deliberate use of specific tools for different jobs, indicating that the objects were made by a craft specialist skilled at working sheet metal.

Other features likely to relate to construction are the lines, faintly incised into the surface of the sheet copper-alloy and only visible in raking light. These appear to mark the overlap of plates making up the sections of the cauldron, and the regular distribution and position of rivets indicating that the cauldrons were carefully designed and made.

Examination is also showing that, while the 12 cauldrons are broadly similar in their design, there are variations in their size, shape and construction. We have already identified three different types of rim construction. These differences are extremely intriguing and suggest that the cauldrons were made by different makers and/or at different times.

Another intriguing feature we are encountering is a high number of patched repairs. Some repairs appear to have been applied at the time of construction and placed over fatigue cracks caused by raising the metal. Others quite clearly cover areas of damage caused during the useful lifetime of the cauldrons, indicating that they were used and repaired over a period of time and were already old and well-loved items at the time of their burial.

Preserved details like this mean that while the cauldrons are in relatively poor condition there are minute pieces of evidence that allow us to build up a wider picture of how the cauldrons were designed and made, and really bring the objects to life by allowing us to see the craftsman’s thought process and the practical application of their art.
