The basics
M
ost brushes
are made from
animal hair and
the quality of the
brush, its bounce and feel is
dependent on the quality of
the hair used. Natural mink hair
make sable brushes and pig hair
make hog brushes.
Are you matching the right
brush to the right medium?
By thinking which of the three
animals have a softer tail, you
will understand one of the most
important things about brushes
- that is, which one is best for
which paint.
Animal or synthetic?
OSable (mink) is soft, holds
loads of water but has a great
spring making it ideal for
watercolour and also for fine
finishing with oils. It returns to
its natural point after use.
These are the most expensive
brushes due to the rarity of the
hair. Usually, it is available in a
short handle because you usually
work with watercolour on the flat.
OSquirrel is super soft, holds
a lot of water and has some
spring. Due to the longer length
of squirrel hair it’s great for big
watercolour washes. It returns
to its natural point when dipped
in water. This is priced much
more reasonably and is usually
available in a short handle.
OHog (pig) is a lot stiffer, holds
little moisture but has strength
and resilience. It’s great to stand
up to the thinners used in oil
painting and for moving thick
paint around the canvas.
Generally used with oils,
they tend to have long handles
allowing you to work upright at
an easel and stand away from
the painting.
OSynthetic are mostly a blend
of synthetic bristles and natural
hair (mink, squirrel or pig). This
enables the manufacturer to
produce a good priced, fine
tuned commercial brush perfect
for beginners. For painters who
object to using animal hair,
there are also pure synthetic
brushes available.
For watercolour painting
you’ll notice a big difference
between natural hair and
synthetic because synthetics
don’t hold enough water but
they can be useful for the larger
washes you want to create.
For acrylics and oils, synthetics
can be fantastic and are a good
alternative to pure natural hair.
They come in both long and
short handles depending on the
medium you want to work with.
What shape do I use?
ORounds are used for 90% of
watercolours because the fine
point allows precision work but
the belly of the brush holds
enough water that you can still
paint quite large areas.
OFlats are good for blocking
in and large areas of colour,
usually oils and acrylics, but
in watercolour there is an
equivalent called a one stroke.
OFilberts are just great for
oils and acrylic. They have a
feathered top so are ideal for
blending and can be used to
block in areas as well as detail
work. For detailed portraits I’d
use 90% filberts.
If I could only buy one brush for
each paint type, it would be a
round for a watercolour, flat for
acrylic and a filbert for oil.

The joy of natural brushes
especially sable are their
ability to hold a lot of
water in the ‘belly’ of
the brush.
