Dendro dating service
Tree-ring dating works because a tree grows larger—not just height but gains girth—in measurable rings each year in its lifetime.The rings are the cambium layer, a ring of cells that lies between the wood and bark and from which new bark and wood cells originate; each year a new cambium is created leaving the previous one in place.Peter Ratcliff is a pleasure to work with, providing detailed reports and giving the buyers as well as ourselves, peace of mind""As experts it is our responsibility to use every single tool available to help us to inform our opinion; dendrochronology is one of these valuable tools, and Peter’s accurate and scholarly approach is a credit to his profession""In our experience Peter's reports are very reliable and serve as an excellent supplement to the ever-evolving study of violin expertise and authentication.Introduction Dendrochronology is used as for exact dating of tree-ring width series of wood.The study material comprises subfossil tree remains from ‘Kiesgruben’ along the rivers Main, Fulda, Lahn, Oker and from peat-bog areas in Northern Germany.

Dendrochronology is the formal term for tree-ring dating, the science that uses the growth rings of trees as a detailed record of climatic change in a region, as well as a way to approximate the date of construction for wooden objects of many types.
As archaeological dating techniques go, dendrochronology is extremely precise: if the growth rings in a wooden object are preserved and can be tied into an existing chronology, researchers can determine the precise calendar year—and often season—the tree was cut down to make it.
