In most cases sampling was done by sanding the cross section and making digital photographs using a picture frame and measuring digitally.The dendrochronological dates of the sampled furniture range between 15.Noting the shapes of the turning ' T ' and the type of buckle are good indications of the age.English and European source tourniquets have multi-curved 'T's, whereas most, but not all American makers typically used rectangular 'T's.Earlier tourniquets have cast buckles and brass prongs, while later models during the Civil War used a steel buckle frame and steel prongs.
The staves were often split out of the outermost part of the tree and hardly any wood was worked away which was proved by the close dendrochronological dates of the single staves of a vessel.
With the help of dendrochronology it was proved that some objects had been painted for some time after construction, or had been over-painted.
Most furniture, however, was painted immediately after completion.
The time span includes time of seasoning and storage and the rings lost by wood-working.
This leads, on the one hand to a short storage time of less than 10 years and on the other hand to very little wood loss due to manufacturing.
