Most
squirrel hair for brushes comes from Canada and Russia. There are three
main types of Squirrel hair: Talahoutky is brown in color and used
mainly for sign brushes; Kazan is brown-black and mainly used in brushes
for watercolor, wash brushes, and watercolor mops; Sacamena is
blue-black, the softest of all the Squirrel hair, and is used for making
some of the best watercolor brushes. This soft, absorbent hair points
well when wet, but has little spring. Squirrel hair brush has good
elasticity and are ideal for washes, letting and smooth painted
finishes.
Squirrel hair brush are very similar to Kolinsky brushes; they point
very well and have thick "bodies" to hold paint, but they lack
the "snap" or springiness of a Kolinsky. This lack of "snap"
makes them almost totally useless when painting with thick paints. Often
squirrel hair is used in the production of "camel hair"
brushes and many other brushes made from mixtures of hair.
