Nowadays there isa delusion that affects the choice of
material by the property developer. Thisfallacy refers to the round log
material. It is thought that the materialbecomes les qualitative after taking
off the “protection layer” and it isbetter to use the hand-processed logs
finished with a wood chopper. Above anydoubts, hand-processing is much more
interesting and prestigious that machineprocessing. But the other aspects have
to sense. If we take 2 logs and shaveoff 2-4 cmwith a wood chopper from one log
and 2-4 cm from the other one with a machine chisel,why is it supposed
that one of them has a “protection layer”?
Let us figure out which layers of wood are the most
firm. The protectionlayer of the tree is its cortex. Sapwood, the most delicate
layer, is situatedunder the cortex. It is responsible for the delivery of sap
to the leaves ofthe tree and is the most exposed layer to the biological and
chemicalaffection. Sapwood represents the young layers of the wood that
surround thecore (ripe wood). In this layer the dip turned into tar (that will
turn intothe amber after several thousands of years). This part of wood is the
mostsolid and accepts all mechanical loads on the body.
