A
brush basically consists of three parts: the handle, usually made of
wood, the ferrule, which holds the hairs onto the handle, and the hairs
or bristles, which can be synthetic or natural. Many scholastic and
mass-produced handles are made of unfinished raw wood. These are the
least expensive, become easily soiled and the wood often swells in use.
The Ferrule is the tapered metal tube that holds the brush hair
filaments.
Ferrules are made of different materials aluminum, nickel,
copper and nickel-plated. Seamless nickel-plated ferrules will usually
appear shinier, with darker tone than aluminum. Brush heads can be
constructed in many shapes and various filaments. There is an almost
limitless choice available to artists but in principle hair type is
divided into three groups soft hair, hog bristle and synthetic
