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.
