Ancient baking left deposits of ash and charcoal, which are very useful for dating.

Results from the juvenile rings, those located closest to the pith, were compared with results from equivalent sections (representing the same calendar years) from independent master isotope chronologies that do not contain any juvenile wood, allowing any juvenile offsets and trends to be separated from those caused by environmental change.

Oak timbers from archaeological sources are often relatively short ( sp., would severely constrain the material available for chronology construction.
