Wood Markings in Cabinets

Cabinetry Factory kitchen cabinets are constructed using many pieces of solid wood and wood veneers. Graining differences, as well as normal color change can be expected. Wood species in all finishes will exhibit color change when exposed to different types of light. Color differences in wood are caused by variations in minerals found in the soil in which the tree was grown and the absorption of these minerals. End grain surfaces and softer areas of the wood may accept more stain and often appear darker than other surfaces. This is a natural reaction when finishing a wood product and potential variances cannot be controlled.

Additionally, every wood species exhibits other characteristics including knots, pinholes, sap runs, and darkening with age. It is the beauty and nature of wood to have these characteristics, as well as natural variations in graining and color, and will be present throughout our cabinetry.

​Birch is a heavy, close-grained hardwood with a light brown or reddish colored heartwood and white or creamy yellow sapwood. Birch has distinct, moderate grain patterns that range from straight to wavy or swirly. Like some other woods, Birch isn’t easily mottled or discolored over time. Due to its closed pore structure, Birch wood stains and finishes easily. It has a smooth, hard surface. Features described below are typical and not considered defects:

• Areas of “short grain” will be present throughout.
• Mineral streaks will appear darker with stain, creating contrast.
• Irregular spots or patches of color can be evident due to various densities in the wood.
• Wavy, curly, and burl graining may appear darker with stain.

​Common Wood Features

Mineral Streaks
Mineral Streaks are caused by the nutrients that the tree absorbs from the soil. This causes the grain to have olive, brown, or black streaks. Depending on how your cabinetry is finished, mineral streaks can appear darker or lighter.

Pin Knots & Sap Pockets
When small branches are torn off a tree or naturally dies, the decaying area then turns a darker color than the sapwood. The knots are a half-inch in diameter or smaller. These markings do not affect the quality of your cabinetry.

Aging of Wood
Wood naturally ages over time. It can lighten, darken, or even change color. Different environment exposures, such as sunlight and temperature, can cause the wood to age more rapidly. This is not considered a defect.
