The idea of this work is to create technology of specific wood modification to selected different tree species to get similar properties to “bog oak wood”. It has been observed that the trees in the bog environment have undergone a great chemical change over the years. Bog wood is a wood preserved in a bog due to anaerobic conditions. The extremely low oxygen conditions of the bog protect the wood from decay, while the underlying peat provides acidic conditions where iron salts and other minerals react with the tannins in the wood, gradually giving it a distinct dark brown to almost black colour. Under the influence of the minerals and iron from the water, the decomposition of wood is considerably slow. When wood is exposed outdoors, the photooxidation or photochemical degradation process begins: the color changes followed by the loss of fibers and surfaces erosion are often observed.
Keywords: iron oxides, iron salt, commercial tannins, phenolic compounds, mass loss, wood density
