Abstract
A process for accelerating the natural aging and darkening of certain reddish-brown tropical wood products. The process uses a chemical solution of potassium dichromate in isopropyl alcohol, which is applied to the surfaces of the wood products. After the chemical reaction has occurred the wood is dried. The resulting wood color is both stable and permanent.

A process for chemically aging wood products having surfaces, the process comprising:
- (a) sanding the surfaces of the wood products;
- (b) applying to the surfaces of the wood products a high concentrate solution of potassium dichromate in a basis isopropyl alcohol;
- (c) allowing sufficient time to pass for completion of a chemical reaction;
- and
- (d) drying the wood product.

A process for chemically aging wood products made from certain tropical wood species having natural reddish-brown color and further having natural oils and resins, the process comprising the steps of:
- (a) preparing a high concentrate solution of potassium dichromate in a basis isopropyl alcohol;
- (b) causing the solution to come in contact with the natural oils and resins in the wood products;
- (c) completing a chemical reaction between the solution and the natural oils and resins;
- and
- (d) drying the wood products;
- wherein the tropical wood species from which the wood products are formed is selected from the group consisting of Hymenaea courbaril, also known commercially as Brazilian Cherry or Jatoba;
- Myroxylon Balsamum, also known as Santos Mahogany;
- Swietenia microphylia, also known as Honduras Mahogany;
