Abstract
Wood samples from South African pine were subjected to thermal degradation of varying degrees, and their dimensional change as well as changes in cell wall density were determined with a micro CT scanner. It was possible to visualise and quantify those changes and also determine a temperature threshold above which the degradation seemed to be too severe to use this wood for any structural purposes. Below this threshold, however, wood properties changed little and the wood may still be of economic value.
