Spalted wood is extremely desirable for woodworkers. It has black wavy streaks that are eye-catching and add a level of detail to any piece of hardwood. The spalted areas of the lumber have a black marble pattern.
Spalted maple is the most common, though it is still extremely difficult to find. We also see the spalted grain pattern on sycamore slabs, oak, and many other hardwoods.
