The laboratory
Based on a sample of wood or charcoal, the 3 axes of the woody plane are observed with a binocular magnifier (magnification x45) and a metallographic microscope (magnification x1000) in order to collect the anatomical characteristics specific to each family, genus and species. The surfaces are sanded with a fine grain (x1500) or refreshed with a razor blade. Around forty anatomical elements are analyzed in comparison with bibliographic and webographic databases and a xylotheque composed of reference wood samples. The photographs are taken with a high-resolution digital camera.
Xylotheque of 2,000 wood samples from around the world.
Under the x500 metallographic microscope
Spiral thickenings observed on a sample of Toromiro (Sophora toromiro ) from a sculpture on Easter Island.
Under the x200 metallographic microscope
Rays with bordering cells observed on the tangential plane of a sculpture from the Vanuatu islands (Species: Serianthes spp.).
Each expert assessment is the subject of a detailed report mentioning all the observations made on the 3 axes as well as photographs of the anatomical elements.
