Maple, Hard Spalted

Caused by fungal decay, spalting imparts wood with dark, contrasting lines that create a veined, marbled look. When caught and dried at early stage of decay, the wood is still very sound and usable with little soft spots or rot.

Colour/Appearance

Small clustered knots resembling small bird's eyes . Colour ranges from nearly white, to an off-white cream colour, sometimes with a reddish or golden hue. 

Grain/Texture

Grain is generally straight, but may be wavy. Has a fine, even texture.

Endgrain

Diffuse-porous; small pores that are uniformly spaced; solitary and radial multiples of 2-3; tyloses or mineral deposits are absent; parenchyma marginal; both narrow and wide rays, spacing normal.

Rot Resistance

Rated as non-durable to perishable, and susceptible to insect attack.

Workability

Fairly easy to work with both hand and machine tools, though slightly more difficult than Soft Maple due to Hard Maple’s higher density. Maple has a tendency to burn when being machined with high-speed cutters such as in a router. Turns, glues, and finishes well, though blotches can occur when staining, and a pre-conditioner, gel stain, or toner may be necessary to get an even colour.

Odor

No characteristic odor.

Allergies/Toxicity

Hard Maple, along with other maples in the Acer genus have been reported to cause skin irritation, runny nose, and asthma-like respiratory effects. 

Pricing/Availability

Figured species should be in the mid range in comparison to other domestic hardwoods.

Sustainability

This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.
