- Chemical reaction
Fumed, or smoked oak is oak wood flooring which has been treated to change its colour. The change in colour comes about from the wood’s reaction to the presence of ammonia in the atmosphere. Effectively what happens is that the ammonia causes the tannins in the wood to be brought to the surface.
Carbonizing is about color, not hardness.
Chemical Reaction flooring are made by the certain special formula with using the reaction of some Acidi/Alkaline reagent and tannic Acid in Oak
