Microwave seasoning
Pulsed microwave energy is directed into layers of timber in a manner that will drive the moisture out of the timber at rates that will not cause seasoning degrade. The process has the ability to deliver energy that can be varied from second to second to suit the moisture content of the timber at the time, and the ambient conditions.
In some cases, microwave energy delivery can be combined with low ambient pressure to give optimal seasoning speeds.
Chemical seasoning
Chemical seasoning, which is sometimes used for very high value applications such as rifle butts, golf club heads and carvings, where the timber is required to be completely free of surface checks. The process involves soaking the green timber (as soon as it is cut) in a hydroscopic chemical for about a day, which slows down the rate of moisture loss and minimises the risk of inducing the internal stresses which cause checking to occur during the subsequent air-drying.
