"Fumed oak", also called "ammonia fumed oak" is our term for today, and it came to mind as I was perusing Craig's List and saw the example listed below, a fumed oak china closet with curved glass doors:
The deep chocolate color of fumed oak was developed by Gustave Stickley, who popularized the Arts and Crafts style of furniture and design. Always experimenting with wood finishes, he discovered that leaving white oak boards in an enclosed space with ammonia fumes given off from bowls of ammonia on the floor would turn the wood the deep color reminiscent of English oak pieces from ancient times. The dark fumed oak became a signature color of the Arts and Crafts style.
Here's another example of fumed oak, this time applied to an Arts and Crafts style table:

Fuming oak produces a durable and scratch resistant color because it causes a chemical reaction that sinks several millimeters into the wood fiber rather than just stain the surface like an applied stain. Other woods can be "fumed" besides oak, too, such as chestnut, although oak is the favored wood.
