The most important

With the taking of the sample it is already decided whether a dating can be successful. If possible, the forest edge - the last annual ring formed by the tree - should be preserved. Only then can the felling year be determined precisely. It is also of decisive importance how many annual rings are available on the sample. There should be at least 50. The more, the better and the more reliable the dating. If no tree slices are available for the evaluation, the samples can also be obtained with a special drill.

The collection protocol

Where do the samples come from? Accurate documentation for processing in the laboratory is imperative. Not only does it record the origin of the wood, it also provides important information about its use in the building or the location of artefacts found in archaeological excavations, thus facilitating reconstruction and later retrieval in the building. In this way, information from the joinery marks also helps us to identify the timbers in the overall context and to recognise second or multiple uses.
