The Types of Hair Used in Finishing Brushes
Almost any type of hair can be used in a brush and most types of hair
have at one time or another. Below are the most common types of hair you
will find in a finishing brush. The both the length of hair exposed from
the tang and the shape of the tip of the brush is variable and is set
when the hair is inserted into the ferrule during the brushmaking process.
China Bristle
is the most common hair found in
finishing brushes. Made from Chinese boars it has the characteristic
of being inexpensive, and available is a wide range of weights and
stiffnesses. While nowhere near as fine as the classic finish brush
material, by "whipping" the brush after manufacture the hair
can be split making it feel and perform as a finer brush.
European Ox hair
is exactly that. Made from the
hair found in the ears of European Oxen it is the finest hair used
for finishing brushes. Before spraying finish was invented, finshers
in both the woodworking and enameling industries (including early automobile
makers) looked for the softest fullest brushes to apply the best, brush-mark
free finishes possible. European Ox, Badger, Squirrel, and Fitch were
the favored choices. Of these types of hair only European Ox is still
available in the quanity and at the cost to make an affordable,
yet high performance brush.
In this brush
china bristle is heavily whipped
in order to break down the fiber and create flags, making for a finer
brush. Then a black streak is painted on the brush to simulate Badger
hair.
This is
real Badger hair
. It's actually a picture
of a shaving brush. You don't find genuine first grade Badger in finishing
brushes because it is several times more expensive than European Ox hair
despite its similar properties. It is still used in artist's
brushes.
Chinese ox hair
is a finer hair than China bristle
and is commonly used for less expensive brushes of medium quality.
Squirrel hair
is used here along with other hair
to make a traditional shellac mop. Another fine hair in the same class
as European Ox it produces a brush of similar characteristics except
it is substantually more expensive and is typically only found is
small shellac mops and artists brushes.
While paint brushes of all kinds are made from Nylon
and other artificial hair,
Golden Taklon
is the best of the
artificial hairs for finish brushes. The hair is very fine and is
especially suited for water-based finishes. The major problem with
these brushes is that they do not hold very much finish and require
constant redipping.
