From their studies, archaeologists attempt to reconstruct past ways of life.Archaeology is an important field of anthropology, which is the broad study of human culture and biology.Bog oak has been used for small turnings and inlay details in furniture for hundreds of years, mainly because it was the only native black timber available, it is unusual to see Bog Oak used in any substantial thickness as traditional drying techniques would have resulted in a great deal of degrade.However due to the development of artificial drying techniques it is possible to dry this precious material in large sections, it is then that the true nature of this rare and visually powerful timber can be appreciated.Archaeologists concentrate their studies on past societies and changes in those societies over extremely long periods of time.With its focus on the ancient past, archaeology somewhat resembles paleontologythe study of fossils of long-extinct animals, such as dinosaurs.There is a lot more to Bog Oak than its colour, for example, it has a weight and density when dry comparable to the world's most expensive and highly prized tropical hardwoods.Over the years many thousands of tons of these extraordinary sub-fossilised trees have been excavated and burnt to enable continued cultivation of the fens.

It is usual at the end of the drying process to have removed from the timber a staggering 3.2 gallons of water per cubic foot, which is over 50% of the trees original volume, and each plank reduces its width and thickness by one third.Making an accurate assessment of the trees structure is critical to the success of the drying process as in my experience they are all different.Excavated trees in truly exceptional condition can be air-dried under very controlled conditions, however, the majority of Bog Oaks have to be dried artificially and be very closely monitored.If you encounter any new question, send me an email to [email protected], I will publish it here.
