Wood
Species
How
do Hardwoods and Softwoods differ?
They look different. Some are smooth, some have bold grain and some have
knots or bird eyes. They finish differently. The density of the various
woods change the depth and tone of the color. The region where the furniture
is made, the style, and the historical period of the price determine the
wood used.
Hardwoods:
Hardwoods are deciduous, the botanical group of trees that have broad
leaves, produce a fruit or nut, and generally go dormant in the winter.
There are hundreds of hardwood species in the United States. Together,
all the hardwood species represent 40 percent of the trees in the United
States.
Softwoods:
In contrast, softwoods, or conifers, from the Latin word meaning "cone-bearing,"
have needles. Widely available softwoods include cedar, fir, hemlock,
pine, redwood and spruce.
The
following is an alphabetical listing of the most popular hard and soft
woods.
Alder
Alder, a relative of birch, grows from Alaska to Southern California.
It ranks third behind oak and pine as the wood most commonly used for
ready-to finish furniture.
Color: Very consistent in color - pale pinkish-brown to almost white.
Grain: No distinct grain pattern
Characteristics: Good working properties, moderately lightweight, low
shock resistance.
Finishing: Finishes smoothly and takes stain well
Ash
There are several species of American ash: black, brown, and white. Like
most other hardwoods the timber of the white ash is heavy, hard, strong
and durable. What sets ash apart and makes it valuable for many special
uses is its exceptional flexibility. Ash is among the most easily steam-bent
hardwood species. Early windmills were made form Ash. Ash is also used
extensively in the manufacture of sporting goods. We all know that baseball
bats are made from white ash. Ash is a popular species for food containers
because the wood has no taste.
Color: Nearly pure lustrous white,
ranging through cream to very light brown.
Grain: It has an attractive, straight, moderately open, pronounced
grain.
Characteristics: Heavy, hard, strong and stiff excellent bending qualities.
Finishing: Because of its large pores it is seldom painted but
takes all other finishes very well.
Aspen
Both quaking and big tooth aspen are readily available as lumber in the
western U.S. Because of it's neutral odor and taste, it is used for food
containers and other food industry needs. In recent years it has become
increasingly important in the manufacture of wood furniture.
Color: Very light and white in appearance.
Grain: Very even grained.
Finishing: Ideal for non-penetrating finishes such as water based
stains and paints.
Beech
Related to the oak and chestnut, beech is most common in the higher altitudes
of the Appalachian Mountain chain. Elegant and attractive, the American
beech is a medium tall tree with the smoothest of all bark. It grows,
naturally, along mountain slopes and rich uplands in nearly pure stands.
It tolerates shade well making it one of the forest trees that can thrive
beneath the canopy of taller species. American beech is an important timber
species. It is highly adaptable to steam bending while retaining its strength.
It is excellent for woodturning, wears well and takes preservatives well.
Because beechwood becomes slick with wear, it is perfect for drawer sides
and runners. Because it bends well, it is used in bent wood chairs and
other bent wood furniture. It does not impart flavor, odor or color to
food so it is good for food utensils and containers.
Color: Wood ranges from nearly white to deep red brown.
Grain: Close and straight grained, with little figure and a uniform
texture, identified by its dark pores in conspicuous rays.
Characteristics: Hard and strong. Good resistance to abrasive wear.
Finishing: Easy to paint, stain or bleach.
Birch
Yellow birch is a deciduous hardwood which grows principally in the upland,
hilly terrain of the Northeastern and Lake States forests: There are nine
species of birch native to North America, including the very distinctive
and familiar white trunked paper birch. But the species named yellow birch
is the most common and important commercial lumber birch. It is identified
by its bright, yellowish bronze colored bark that peels in long, thin
horizontal strips.
Color: Cream or lightly tinged with red.
Grain: Fine grained (often curly or wavy).
Characteristics: Heavy, strong, hard, and even-textured.
Finishing: Birch takes paints and stains well.
Cherry
Like all fruit trees, cherry belongs to the rose family and was used as
early as 400 B.C. by the Greeks and Romans for furniture making. Cherry
helped define American traditional design because Colonial cabinetmakers
recognized its superior woodworking qualities. Today, cherry helps define
Shaker, Mission and country styling. The wood from the cherry tree can
be described in a single word: beautiful. Its rich red-brown color deepens
with age. Small dark gum flecks add to its interest. Distinctive, unique
figures and grains are brought out through quarter sawing. It has an exceptionally
lustrous appearance that glows. The finish is satiny to the touch
Color: Rich, reddish-brown. Cherry darkens considerably with age
and exposure to sunlight.
Grain: Straight-grained and satiny. Small gum pockets produce distinctive
markings.
Characteristics: Light, strong, stiff and rather hard. Cherry's
grain is more subdued than some other hardwood species, with very interesting
character.
Finishing: Cherry is unsurpassed in its finishing qualities-its
uniform texture takes a finish very well.
Eucalyptus
The eucalyptus genus represents more than 300 species. They have been
successfully planted in South America, South Africa, Europe and the United
States. Color: It is pinkish-brown in color and turns to a reddish-brown
with age and exposure to light.
Characteristics: Its' resistance to decay is relative to teak.
Eucalyptus is a heavy hardwood that earns high marks for strength. Eucalyptus
is a renewable resource with high productivity in relatively short harvest
rotations. The wood in these products comes from well managed forests,
independently certified in accordance with the rules of the Forest Stewardship
Council (FSC).
Hickory
A Native American tree, hickories are members of the walnut family. Hickory
is the hardest, heaviest and strongest American wood in common use. Westward
trekking pioneers allegedly made hickory a prerequisite for their wagon
wheels.
Color: White to tan to reddish-brown with inconspicuous fine brown lines.
Grain: Fine grain.
Characteristics: Extremely tough and resilient, even texture, quite
hard and only moderately heavy.
Finishing: The grain pattern welcomes a full range of medium-to-dark
finishes and bleaching treatments.
Mahogany
The heavyweight of all woods, mahogany is one of the most valuable timber
trees. Popular in the '50's, mahogany is making a comeback due to the
new attraction to the "red" woods. On an interesting note, new
model automobiles were originally carved, full sized, entirely out of
mahogany! Each piece, no matter how big or small, from the front bumper,
to the engine, the dashboard, the drive shaft, back to the lock on the
trunk is first fashioned from this very stable hard wood.
Color: Varies from light red or pale tan to a rich dark deep red
or deep golden brown, depending on country of origin.
Grain: It is generally straight grained but is prized for its figures
which include stripe, roe, curly, blister, fiddleback, and mottle.
Characteristics: Extremely strong, hard, stable and decay resistant
Finishing: Finishes and stains to a beautiful natural luster.
Maple
The American species of maple are divided into two groups: Hard maple,
which includes sugar and black maple; and soft maple, which includes red
and silver maple. Until the turn of the century, the heels of women's
shoes were made from maple, as were airplane propellers in the 1920s.
Maple has been a favorite of American furniture makers since early Colonial
days. Hard maple is the standard wood for cutting boards because it imparts
no taste to food and holds up well.
Color: Cream to light reddish-brown.
Grain: Usually straight-grained and sometimes found with highly figured
bird's-eye or burl grain. Bird's-eye resembles small circular or elliptical
figures. Clusters of round curls are known as burl.
Characteristics: Heavy, hard, strong, tough, stiff, close-grained
and possesses a uniform texture. Maple has excellent resistance to abrasion
and indentation, making it ideal flooring as well as cutting boards and
countertops.
Finishing: Takes stain satisfactorily and polishes well.
Oak
The oaks-red and white-are the most abundant U.S. hardwood species. It
would be difficult to name a wood with a longer and more illustrious history
in furnishings and interior design. Oak was a favorite of early English
craftsmen and a prized material for American Colonists. White oak is just
one of 86 oak species native to this country, but it is the classic oak
of America. Although prevalent throughout the eastern half of the United
States, from Maine to Texas, white oak lumber comes chiefly from the South,
South Atlantic and Central States, including the southern Appalachians.
Red oak grows only in North America and is found further north than any
other oak species. A big, slow growing tree, red oak takes 20 years to
mature and lives an average of 300 years.
Color:
White Oak- ranges from nearly white sapwood to a darker gray brown heartwood,
Red Oak-ranges from nearly white cream color to a beautiful warm, pale
brown heartwood, tinted with red.
Grain: The grain is distinguished by rays, which reflect light
and add to its attractiveness. Depending on the way the logs are sawn
into timber (rift-cut, flat sliced, flat sawn, rotary cut, quartered),
many distinctive and sought after patterns emerge: flake figures, pin
stripes, fine lines, leafy grains and watery figures.
Characteristics: Heavy, very strong and very hard, stiff, durable
under exposure, great wear-resistance, holds nails and screws well.
Uses: Flooring, furniture, cabinets, ships and decorative woodwork.
Finishing: Oaks can be stained beautifully with a wide range of
finish tones.
Parawood
Parawood is A Native tree of the Amazon Region of South America. Information
about Parawood can be traced back to Christopher Columbus. It was during
his second visit to South America, that he wondered at the heavy black
ball the natives were using in games. This black ball was made from the
vegetable gum of the Parawood tree. Later historians would also marvel
at this substance, which bounced so much when thrown to the ground it
appeared to be alive. In the 19th century an Englishman named Henry Wickham
transported some seeds to England for germination. The seeds germinated
and these small seedlings were then transported to the Malay Peninsula
for planting; there to start the Great Rubber Plantations of Malaysia.
After 25 to 30 years of latex production, tapped in the same manner syrup
is tapped from the Maple trees, the tree ceases to produce sufficient
quantities of latex. The tree is cut for processing in the manufacture
of fine furniture and a new tree is planted in its place.
Color: Pale yellow.
Grain: Open grain similar to mahogany.
Characteristics: A very hard wood.
Finishing: Takes a very even stain.
Pine
(Radiata)
Radiata Pine is a plantation-grown wood from South America and New Zealand
that is harder than other pines and has fewer knots.
Color: Pale cream color.
Grain: Has a distinctive grain pattern.
Finishing: Takes most finishes well.
Pine (Southern Yellow)
Southern Yellow Pine is actually a species group that is made up of primarily
four trees: loblolly pine (Pinus taeda), long leaf pine (Pinus palustris),
shortleaf pine (Pinus echinata) and slash pine (Pinus eliottii) Loblolly
Pine is the most important and predominant of the four. It grows throughout
the Atlantic Coastal Plain, often in commercial stands, from Maryland
south through all the Carolinas and Georgia into Florida, and westward
to East Texas. It is classified as a hard pine and is harder than white
pine.
Color: Warm pale yellow with brown knots.
Grain: Distinctive light and dark grain pattern.
Finishing: Pine takes most finishes well. With some stains, a sealer
helps prepare the wood to achieve a more even look.
Pine
(White)
Found in the uplands of Newfoundland, Ontario and Manitoba in Canada,
south throughout New England and the Great Lakes Region to South Carolina
White Pine is the state tree of Maine and Michigan. A very large tree
with relatively few horizontal big limbs, the Eastern white pine is one
of the tallest timber trees in the Northeast.
Color: white to pale yellow with a reddish tinge. It darkens with
age and air exposure, eventually turning to a deep orange color.
Grain: The wood is light, soft, straight grained and with very
uniform texture.
Characteristics: It works very well and is easily shaped with hand
and power tools. This wood accepts many types of glue well, making for
tight bonding.
Finishing: Pine takes most finishes well. With some stains, a sealer
helps prepare the wood to achieve a more even look.
Poplar
Also known as yellow poplar, tulip poplar, tulipwood and hickory poplar,
-poplar trees grow taller than any other U.S. hardwood species. The yellow
poplar grows quickly into a tall straight tree. It is found alone in open,
rich, moist soil. Because of its fast maturity the lumber from poplar
is lightweight and soft for a hardwood. But it is strong, durable and
seasons well resisting warping once it is dried. Because the trunk has
no limbs or branches, except at the very top, the wood has no knots.
Color: White to yellowish cast, sometimes with slightly greenish
cast and occasionally with dark purplish streaks.
Grain:. It is straight grained and evenly textured.
Characteristics: Comparatively uniform texture, light to medium weight,
excellent strength, and stability. . It cuts and sands well, keeps its'
edge and resists splitting.
Finishing: The wood stains well and can easily be made to resemble
walnut or maple. Because it takes paint exceptionally well, it is often
painted.
