Thermowood: The molecular structure of wood is altered in a kind of “baking” process at high temperature. The wood sugar is caramelized and the pores are closed. Exposure to heat gives the wood a fine, dark color. Wood processed in this way is called thermowood. It absorbs little or no water and is thus practically insensitive to moisture.
