Spalted Maple is maple lumber that has undergone partial fungal decay, creating dramatic black zone lines and color patches throughout the wood. The wood is harvested before the decay progresses to structural weakness.

The black zone lines in Spalted Maple are produced by certain fungi that colonize the wood and create melanized barrier zones between competing fungal colonies. These dark lines, called 'zone lines', demarcate the territory boundaries between different fungal species and are the defining visual characteristic of spalted wood.

Spalted Maple varies widely in structural soundness depending on how far the decay has progressed. Lightly spalted material maintains its strength. Heavily spalted wood can be punky, soft, and structurally compromised.

Yes. Spalted Maple is very popular for woodturning, particularly for bowls, platters, and decorative vessels. Its black zone lines and color variations make turned pieces look incredible.

Spalted Maple features a creamy white to light tan base color (from the underlying Maple) overlaid with black zone lines, patches of grey, green, brown, and other staining colors produced by various fungal species.

Yes. Soft or punky Spalted Maple can be stabilized using vacuum-infused resin that hardens the wood fibers and restores workability.

Clear oil-based finishes, lacquers, and hardwax oils show off Spalted Maple's dramatic natural patterns best. Any punky areas should be hardened with thin CA glue and sanded smooth before applying a topcoat. Water-based finishes can raise the grain significantly on softer spalted areas, so oil-based products tend to have better results.

Spalted Maple is more expensive than regular Maple because if its rarity, the difficulty in sourcing pieces.

Spalted Maple is not recommended for cutting boards because of the uncertainty about the structural integrity of punky areas and the ongoing nature of fungal activity. For decorative items not in direct food contact, it is beautiful.
