Mineral streaks are caused by nutrients
that the tree absorbs from the soil. This
causes the grain to have olive, brown,
or black streaks. Mineral streaks can
appear darker or lighter depending on
how your cabinetry is finished.
Pin Knots & Sap Pockets
When small branches are torn off a tree or
naturally die, the decaying area turns a
darker color than the sapwood. These
knots are a half-inch in diameter or smaller.
This does not affect the quality
of your cabinetry.
Aging of Wood
Wood ages over time and can lighten,
darken, or even change color.
Environmental exposures such as sunlight
and temperature can age wood faster.
