The Process of Wood Carbonization
In remote times, the process of wood carbonization used to be more rudimental. It entailed burning the outer layer of the wood almost manually. Nowadays, however, the carbonization process of the boards is usually carried out with a torch. This modern approach forces the timber’s external fibers to react and burn with more precision.
Using a torch also allows the expert to heat the wood’s entire surface uniformly and with the same intensity. To achieve this, the artisan can even place the wood in a closed vessel. Burning lumber in an enclosed environment is the only way to extract the oxygen from the equation. Creating an anaerobic state is vital. It allows the wood to burn without combusting.
If the wood were to combust, it would burn away and turn into ash. This process must be carried out by trained specialists that know how to preserve the wood properly. The method of wood carbonization requires four steps.
- Burning: This step should take part either before its installation and never performed onto a façade or floor.
- Brushing: After the burning, it’s time to clean up the charred timber with a special grit. This procedure removes the top layer of carbon and gives a new shade to the wood.
- Treating: The wood should have a black tone by this stage. The specialist should now dress the surface with natural oil. This step will provide greater resistance and endurance.
- Sealing: To avoid staining and other types of damage, charred wood should receive a sealant layer. This preventive measure also helps give it the desired finish. However, this step is entirely optional.
