What is a Mineral Streak?

A mineral streak is a discoloration in wood that is caused by mineral deposits. These deposits can come from soil or water and can leave behind traces of minerals such as iron, manganese, and calcium. Mineral streaks are usually darker than the surrounding wood and can be gray, brown, or black in color. They can be straight or wavy and may or may not follow the grain of the wood.

Mineral streaks are a natural characteristic of wood and can add interest and uniqueness to a piece of furniture or cabinetry. However, they are sometimes considered defects and can affect the grade and value of the wood. In some cases, mineral streaks can be minimized or removed through staining or sanding, but this can also remove some of the character and natural beauty of the wood. Ultimately, whether mineral streaks are desirable or not depends on personal preference and the intended use of the wood.
