Fuming is the process of exposing wood to ammonia vapors that darken the wood and emphasize grain patterns. Like other styles in woodworking, fuming has gone in and out of style but for now it is once again in high-demand.

The process takes place in a multi-chamber closed system under continuous control that utilizes environmentally-friendly vacuum technology. The wood is placed into a chamber where it is exposed to ammonia gas for two weeks. After this treatment has taken place, the residual ammonia is pumped into another chamber where it is neutralized. The entire process takes about 3-4 weeks to complete and results in a dark coloring going all the way through the wood.

Fuming can be successfully performed on any wood containing tannin. The concentration of color being dependent upon the amount of tannin within the specie. This is one reason why from specie to specie the absorption and resultant darkening is so different. Thanks to differing levels of tannin the color from fuming can vary from honey-brown to rich chocolate to almost black. Other effects of fuming are increased smoothness and flexibility of the veneer.

The most common specie that’s fumed is White Oak but Interwood offers over a dozen fumed species.

Having been in the veneer industry for over 41 years, I have never seen any one tree produce the quality, color, consistency, and size of veneer which this Sapeli tree has produced. It is truly a marvel in its own right.

The tree yielded 1,253 bundles of veneer totaling 436,896 square feet, which averages 349 square feet per bundle. The average width is over 12 inches with the widest being 24 inches. 75% of the veneers produced from this tree are over 12 feet long.

A tree of this magnitude demands a special architectural project. This gem of the forest is 100% FSC Pure.
