SUMMARY
Pottery sherds can be dated by four methods: (i) stylistic features; (ii) luminescence analysis of minerals within the sherd; (iii) 14C assay of carbon on or within the sherd; and (iv) archaeomagnetic intensity of the sherd. Each method has its own sources of uncertainty. The results obtained by the various methods are reviewed, and the conclusion reached that a combination of at least two of the methods, where possible, is recommended in order to enhance confidence in the validity of the outcome.
