摘要： The present invention implements a method to produce stained oak, having features identical or very close to a bog (black) oak wood found in wetlands. This method is based on the reaction of iron with the tannin present in the wood, and it comprises the following steps: placing the wood blank into a metal container; filling the container with water (or other suitable solvent), so that all the blanks are submersed; blending iron oxide into the solvent and producing the solution of iron oxide of a suitable concentration; heating the container to the desired temperature between 60 to 100 degrees Celsius; maintaining the temperature of the container for a certain period of time, depending on the dimensions of the blanks; compensating the water that was lost during the process due to evaporation by adding an additional amount of water; after the determined period of time or when the desired shade of wood (black, gray, blue, purple, or brown) is achieved and/or the desired density is reached; stopping the heating process and discharging the water from the tank; washing the blanks; drying the blanks in sawdust or using other desiccation means; and/or drying the blanks in convection or vacuum dryer, or using other similar means, until a needed moisture content is reached.
