Dating techniques for pottery

Dating techniques are procedures used by scientists to determine the age of an object or a series of events.

The main relative dating method is stratigraphy (pronounced stra-TI-gra-fee), which is the study of layers of rocks or the objects embedded within those layers.Cassette tapes or eight-tracks might be the first things that come to mind when thinking about dated magnetic storage, but Bronze Age clay pottery has them both beat.Using information stored in the clay’s magnetic minerals, scientists are developing methods to determine how old these artifacts are when other dating methods come up short.This method is based on the assumption (which nearly always holds true) that deeper layers of rock were deposited earlier in Earth's history, and thus are older than more shallow layers.The successive layers of rock represent successive intervals of time.
