Direct Dating of Wood Cross-dating determines the age of undated wood by directly matching ring patterns with trees of known age.Greatly simplified, the process samples living and dead trees in a given area.The tree-ring patterns are matched, and laid down in series, building a continuous timeline of known dates.Once the timeline exists, the age of similar wood (e.g., from a nearby house) can be established by pattern-matching.The precise, extended chronology of these trees is directly responsible for the accuracy of radiocarbon dating.Radiocarbon Dating Founded on a false belief that levels of carbon isotopes never vary, initial radiocarbon dates were commonly off by hundreds of years.His growth rings document nearly 47 centuries of survival.Bristlecones grow so slowly that a century of tree rings adds less than an inch of girth.

In dead material, the decayed 14C is not replaced and its concentration in the object decreases slowly.If any organizations or other pertinent information has been inadvertently excluded please contact MCI.Purpose To determine the absolute age of wood and organic artifacts.The combined results of the stylistic, material and scientific investigations will permit the establishing of the compatibility of the painting with presumed elements or its inauthenticity.Thanks to the laboratory's modern equipment, a painting can be subjected to analysis using infrared reflectography, Wood's light, a stereoscopic microscope, IR spectroscopy and other instrumental techniques.3 e 4 - Microscopic analysis to examine the signs of ageing in the paint layer: the nature of the craquelure (natural or artificial - deep or superficial), the pigments (crystallinity, purity and size), restoration and other factors.
