During excavations by Chester Archaeology at the site of Chester Royal Infirmary, the remains of a post medieval pipe kiln were discovered. It is often possible to date such features precisely from the typological analysis of the clay pipes that they produced, hence the Ancient Monuments Laboratory was contacted with a view to sampling the kiln to improve archaeomagnetic calibration information for the period. Unfortunately, despite the magnetisations of samples from the kiln being stable, it appeared that the feature had slumped since it was last fired and it was not possible to date magnetically.
