Strength and mechanical properties
The roots of the walnut tree release
a toxic material which may kill other plants growing
above them.
From the time of ancient Greeks until
well into modern European history, walnuts symbolized

Just the opposite, in Romania, brides
who wished to delay childbearing placed into the bodice
of their wedding dresses one walnut for each year they
hoped to wait.

General Description
The sapwood of walnut is creamy
white, while the heartwood is light brown to dark
chocolate brown, occasionally with a purplish cast and
darker streaks.
The wood develops a rich patina that
grows more lustrous with age. Walnut is usually supplied
steamed, to darken sapwood.
The wood is generally
straight-grained, but sometimes with wavy or curly grain
that produces an attractive and decorative figure.
This species produces a greater
variety of figure types than any other.
Working Properties
Walnut works easily with hand and
machine tools, and nails, screws and glues well.
It holds paint and stain very well
for an exceptional finish and is readily polished.
It dries slowly, and care is needed
to avoid kiln degrade.
Walnut has good dimensional
stability.
Physical Properties
Walnut is a tough hardwood of medium
density, with moderate bending and crushing strengths
and low stiffness.
It has a good steam-bending
classification.
