Radiocarbon dating generally is not reliable for samples postdating c.

Impressed into clay tobacco pipes are bits of data that have fueled endless research avenues since the earliest days of archaeology on historic sites excavated on both sides of the Atlantic Ocean.

For Historical archeologists, ceramics are a diagnostic tool for dating because many English ceramic types can be dated to within 5 or so years of their manufacture.

Access to this knowledge led to something called the Mean Ceramic Date.
