The process is fairly simple. Burn the planks on both sides to the desired amount of char. The carbon exterior will release the moisture inside the board as gas and steam. (Think of it as turning the wood’s surface into a chemical compound similar to the pure carbon a diamond.) After cooling the boards, brush and wash them to your aesthetic liking—the amount of char cleaned off changes the look of the wood. Finally, you can seal the board with a natural oil of your choice, or leave it unvarnished.
