Fuming wood veneer is a process used to darken and enhance the natural color and grain of the wood. It typically involves placing the wood veneer in a sealed chamber along with ammonia fumes. As the ammonia gas reacts with the tannins present in the wood, it gradually darkens the veneer over a period of several hours to days. The duration of fuming depends on the desired depth of color. Once the desired color is achieved, the veneer is removed from the chamber, neutralized, and thoroughly cleaned to eliminate any residual ammonia. Finally, the fumed wood veneer can be further processed, finished, and used in various applications, such as furniture making or flooring, to showcase its rich, aged appearance.
