Flame treatment of wood changes its surface, but the material stays intact. This technique is suitable for all types of wood that are to keep their historical character and get darker in colour.
The singed planks go through an intense fire cycle. Afterwards, they are washed properly in preparation of surface processing. This treatment cycle results in hard wooden parts remaining, while soft parts are removed.
We distinguish between chopped burned washed—resulting in a very rustic surface—and burned washed, with the same colour as a result but a more elegant structure.
