GOAT HAIR:
A very fine hair with limited elasticity. It has a natural kink that
cannot be straightened. Used for short trim [2-1/8 maximum folded trim
length] soft brushes. Available at Gordon Brush in natural black and
white, and dyed in blue, brown, gold, green, gray, and purple.
HOG BRISTLE:
Relatively scarce and expensive. This material has characteristics that
set it apart as the best natural filling material for a wide variety
of brushes. Each strand of bristle has a natural taper from the butt
or flesh end to the tip, giving it resilience not found in other hairs.
In addition, the tip end of each bristle is naturally split into two
or more branches called the flag. Hog bristle has a soft to slightly
stiff texture and is brown, black or gray in color. It has excellent
durability and water resistance.
HORSEHAIR:
Horsehair is a medium to high cost material. Tail hair is stiffer than
mane hair. Its soft to slightly stiff texture gives a scratch-free dry
cleaning and has very good durability. Not resistant to acids or alkalis.
Used for buffing, cleaning, dusting, and finishing in a variety of brush
styles: floor sweeps, shoe shine brushes, tin handle acid brushes, counter
dusters, and window brushes. Heat distortion temperature is 370º F.
OX HAIR:
In proportion to its diameter, ox hair is perhaps the stiffest of all
soft hairs. Ox hair is particularly sought after for fine lettering,
striping and marking brushes.
RED SABLE:
The hair of the red sable is the most valuable of all soft hairs. It
is very fine, has strong, sharp points and great elasticity and carries
color well. Red sable hair makes the finest artists' brushes, being
particularly suited for use with Japan colors, oil colors and heavy-bodied
sign-writing materials, and is best for fine lettering.
SKUNK OR FITCH:
This hair is rarely used alone. Combined with Chinese bristle, it makes
excellent sign writer's brushes. Grey skunk hair from eastern and western
Europe has been found to be ideal for brushes used in the manufacture
of shade cloth.
SQUIRREL:
This hair is divided into blue squirrel and Canadian squirrel. A very
fine hair used for applying thin lacquers, Japan colors, light-bodied
varnishes, and for general artwork, lettering and striping.
