PEATLAND
COLLECTIONA WEALTH OF NATURAL HISTORY BURIED IN A PEATLAND
alcarol recovered some unusual black trunks of oak trees lain in a small Alpine peat.
The radiocarbon dating revealed their age:5th century BC.
A peatland is a wet area that accumulates deposit of dead plant material where the water at the ground surface
is acidic.anaerobic and low in nutrients.
Deprived of oxygen,the buried wood undergoes the process of fossilization.The peat protects the wood from
normal decay.while the underlying peat with iron salts and other minerals react with the tannins in the
wood,gradually giving it a distinct dark brown to almost black color.
This millennia-long process also increases the hardness of the wood to such a degree that it can only be
carved with the use of special cutting tools.
Sites of quality peat wood in the world are extremely rare and saving it is a rather delicate matter.
The process of wood desiccation is very complex,and despite great care.most of the raw wood is unsuitable
for further processing.
alcarol selects the most suitable trunks and cuts the pieces.preserving the natural eroded outer surface.
Then.the innovative resin process is used to emphasize this precious wood with transparent resin volumes.
resembling the peat water that has conserved them for millennia.
The natural wood surface it's not covered by resin on the section planes,so you can touch the warm organic
vibrancy of such an ancient materiaL
