Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped-charge dating methods such as thermoluminescence dating of glazed ceramics. The absolute dating is the technique to ascertain the exact numerical age of the artifacts, rocks or even sites, with using the methods like carbon dating and other. For example, if a context is sealed between two other contexts of known date, it can be inferred that the middle context must date to between those dates. An example of a practical application of seriation, is the comparison of the known style of artifacts such as stone tools or pottery.
