Wood Supply

Wood is not an ordinary material like metal, steel or plastic. It is, in fact, the first humans used for constructing tools and houses; it comes from living beings and when you work in it, you can get stuff of great beauty.
Wood is a cell tissue made of cellulose, lignine, resin, starch and other sugar derivates. Wood suffers no expansion with heat, as occurs with almost all mineral materials. On the contrary, with temperature elevation, wood loses humidity and decreases its volume: this is an important difference with the inorganic materials. 
If you cut a trunk, the main part of the tree from where wood is taken of, you will see the rings that testify the age of the plant. And if you cut the trunk perpendicularly you will not see the rings: the wood acquires a really different aspect.
Density and weight of the wood are given by the density and type of cells the tree is made of. You can see defect on the wood depending on the shape of the trunk. For example: a broken vein is produced by conic trunks. Seemingly, twisted veins are due to the pressure wind makes over the tree, bending it when wood is dried.
The color of the wood can vary with the species and the time of the tree cut.
The vein is also typical for each species of wood.
And about quality, always remember: the harder the wood, the better.
