Dendrochronolgical analyses on art objects Dendrochronology is a discipline of biological sciences which determines the age of wooden objects. This method is used primarily for dating archaeological and architectural objects, but may also aid in investigating art-historical problems The main goal is to offer at least a terminus post-quem for the creation of a painting by determining the felling date of the tree which provided the wood for the panel. Dendrochronology focuses on the annual periodicity of growth which is controlled by the climate, e. In cool and temperate climates, there is a dormant season from autumn to spring and a growth season during the summer. When the vegetative period begins, new cells for the transport of water from the roots to the top of the tree are formed. During the summer, the so called latewood formation starts, and around the middle of September the radial growth of the tree stops and rests up to the next spring. The result is an annual ring or tree ring. Besides the differences in structure, two species of wood differ physiologically: in ring-porous wood the latest growth ring fulfils the major task of water transport and, consequently, a new ring must be formed every year. In diffuse-porous woods and in conifer wood, some growth rings participate in the water conduction. Hence, under adverse climatic conditions, the trees do not need to form a growth ring every year and may be characterized by totally or partially missing rings.

Our view of the ancient past is set to become a bit clearer after an international team of scientists completed a major recalibration of radiocarbon dating. The seven-year global effort used almost 15, samples from a variety of sources to draw new, more accurate calibration curves to enable more precise dating of objects as old as 55, years. First developed by Nobel Prize winner Willard Libby in , radiocarbon dating is one of the most powerful tools for archaeologists and geoscientists, allowing them to directly date objects that are tens of thousands of years old.
The technique is based on the fact that the Earth’s atmosphere is constantly being bombarded by cosmic rays, some of which collide with nitrogen atoms and convert them into the radioactive isotope carbon Other than being radioactive, carbon is just the same as the much more common, stable isotope carbon and is absorbed in almost exactly the same way by living plants and animals. This means, theoretically, that the ratio between the two isotopes remains constant.
When a plant or animal dies, it stops absorbing carbon and the ratio between carbon and carbon starts to slowly change. Like all radioactive elements, carbon decays at a constant rate with a half-life of about 5, years, so every 5, years there will be half as much carbon in the remains as when the plant or animal died.
This means that if you can measure this change in the ratio, it can act like a radioactive clock, revealing the age of the remains or of some object that’s been made out of them. Over the decades, the technique has been refined by introducing things like isotope concentration, mass spectrometry, and particle accelerator dating, which allows scientists to date samples that have shrunk from 15 g 0.
Unfortunately, there is a stumbling block in that radiocarbon dating isn’t that simple.
