Cherry -
(Prunus serotina) Cherry is a domestic hardwood. The
heartwood is a medium red-brown with it’s own characteristic luster. The
sapwood is narrow and nearly white. The grain is straight, finely
textured and close with usually a gentle waving figure. Cherry has a
uniform texture, is medium heavy, strong, stiff and moderately hard.
Cherry is one of the most sought after hardwoods. Cherry turns darker as
it ages. The tree reaches heights of
up to 100 feet, about 80 feet average, with a trunk of about 24''
in diameter.
Burl - (British bur or burr) is a tree growth in which
the grain has grown in a deformed manner. It is commonly found in the
form of a rounded outgrowth on a tree trunk or branch that is filled
with small knots from dormant buds. Burls are the product of a cambium.
A burl results from a tree undergoing some form of stress. It may be
environmental or introduced by humans. Most burls grow beneath the
ground, attached to the roots as a type of malignancy that is generally
not discovered until the tree dies or falls over. Such burls sometimes
appear as groups of bulbous protrusions connected by a system of
rope-like roots. Almost all burl wood is covered by bark, even if it is
underground. Insect infestation and certain types of mold infestation
are the most common causes of this condition. In some tree species,
burls can grow to great size. Some of the largest occur in redwoods
(Sequoia sempervirens); when moisture is present, these burls can grow
new redwood trees. The world's largest and second-largest burls can be
found in Port McNeill, British Columbia. One of the largest burls known
was found around 1984 in the small town of Tamworth, Australia. It
stands 6.4 ft tall, with an odd shape resembling a trombone. In January
2009, this burl was controversially removed from its original location,
and relocated to a public school in the central New South Wales township
of Dubbo. Burls yield a very peculiar and highly figured wood, one
prized for its beauty by many; its rarity also adds to its expense. It
is sought after by people such as furniture makers, artists, and wood
sculptors. There are a number of well-known types of burls (each from a
particular species); these are highly valued and used as veneers in
furniture, inlay in doors, picture frames, household objects, automobile
interior paneling and trim, and woodturning. The famous birdseye maple
superficially resembles the wood of a burl but is something else
entirely. Burl wood is very hard to work in a lathe or with hand tools
because its grain is misshapen and not straight. |
