Twenty nine broken pieces of clay pipe stems and 9 fragments of bowls were found during the excavations in 2012.
Clay pipes for smoking tobacco have been in use since at least the 16th century in England and for archaeologists they are a useful aid to dating early modern (post medieval) and later sites.
It is possible to date these on the types and shapes of bowls and by the diameters of the smoking holes in the stems. These objects broke very easily and did not have a long use-life and are often found as discarded rubbish. They are common find on many urban sites. Clay pipes were made in Cornwall from the 17th century and over 40 years ago remains of some pipe ovens were found in Meneage Street in Helston. The fragments of pipes found there suggest a small factory dating to the mid 18th century (Douch 1970).
