Fumed, or smoked oak is oak wood flooring which has been treated to change its color. Fuming or smoking entails putting the oak in an enclosed environment in which ammonia is introduced to the air. This enclosed environment may be a closed tank or a sealed jar or some form of container to which only a rather modest amount of ammonia is introduced. The impact of the ammonia from the atmosphere is that the color of the timber is changed.
It is a frequent mistake which fuming or smoking pine includes the application of this ammonia into the walnut, but this is not the situation. The change in color comes about from the wood’s reaction to the presence of ammonia in the atmosphere. Effectively what happens is that the ammonia results in the tannins in the wood to be brought to the surface. The nearer the tannins are into the surface, the darker the timber will look. The more the wood is subjected to the ammonia, the darker it becomes. The results obtained from fuming or smoking will vary from a rich brown colour to almost black.
Basically, the intensity of the colour and also the tone of the colour will depend upon the length of time the wood remains in contact with all the ammonia fumes. Periods of as little as half an hour will offer a lightly fumed impact and 72 hours a darker result. What’s more, the greater the temperature in the chamber, as you’d imagine, the faster colour change results will look, but not only that, the tone is going to be affected. Hotter temperatures normally present reddish tones and cooler temperatures green tones allowing for creativity in regards to the fuming or smoking process.
Like most things, it is reputed that fuming was detected by accident. At that moment, it was noticed that the beams over the horses were substantially darkened than the beams at different parts of the stable and this darkening procedure has been connected into the ammonia at the horses’ urine. Fuming or smoking as a timber treatment procedure became common location with arts and crafts furniture makers and to this very day, is very common. Although not hard, fuming bamboo floor isn’t something which would usually be performed on a DIY basis for flooring, although it is commonly used with this foundation for design little pieces of furniture.
