The very interesting thing about wood is not only its diversity in grain, color, fragrance & patterns….but as well, it can carry countless traces of its life on the planet.
Traces of those characteristics can be visible in all types of wood. Those typical traces can be for example;
A knot in a piece of wood that is firmly fixed, undecayed, and as strong as the surrounding wood. Also known as tightknot.
An unsound knot is a circular area that was the base of a branch that has a pith center.
This is a swirl or twist in the grain of the wood that does not contain a knot.
These are small marks in the grain pattern caused by pecking birds.
Wormholes are traces of previous wildlife in the wood. They can range in size between 1 mm. up to 4 cm. (0.04 to 1.57 inch.)
They are an olive to blackish-brown color, following a grain pattern.
Gum streaks are mineral-like streaks of color naturally occurring only in Cherry wood.
This is the mature, usually darker wood, extending from the sapwood to the pith.
Sapwood is lighter colored wood growing from inside the bark to the heartwood.
