Finding the etymological origin of the term brush leads us to have to move to Catalan, since it emanates from the word "pinzell". This in turn emanates from the vulgar Latin "penicellus", which was the word used to refer to what was the tail of four-legged animals.
Brush is a instrument which has a long and thin handle that, at one of its ends, presents a bunch of bristles, hairs or other filaments . The brush can be used to draw or paint: what is done is to soak the bristles in painting or other similar substance and then slide them on the surface that is intended to be painted. The brush will leave a trace of paint.
Every brush has three fundamentals: the handle, the splint and the hair.
For example: “I need to buy a new brush to paint the door frames”, “The artist has a collection of more than a thousand brushes since, once they are no longer useful, he saves them as a souvenir”, “The drawing teacher asked us to bring brushes of five different sizes to class”.
The most important element of the brush is the hair. It can be about natural animal hair or of synthetic filaments . According to the hardness of these hairs, the brush will have different characteristics that will determine the possibilities it offers to paint or draw. The less rigid hairs are those that allow smoother and more delicate strokes.
As for the type of hair it should be said that the brushes with the most frequent animal hairs are those of sow, those of red marten and those of maol kolinsky. The latter is considered the best hair and that is why it is the most expensive, considering also that it comes from an animal that lives in northern Siberia and is in danger of extinction.
There are many different brushes, in terms of shapes, so that anyone who uses them can find the one that best and best suits their tastes, their work or their objectives. However, among the most significant are the following:
• Fan brush, which is used primarily for what would blur the charcoal.
• Round tip brush, which is the one used to carry out tasks that require much more detailed and finer work.
• Cat tongue brush, which is very useful to perform a wide variety of tasks since it perfectly combines what are the advantages of the round tip brush with those of the flat brush.
Another very important characteristic of the brush is its width. The wider your hair bundle, the greater the thickness of the strokes. This means that, to paint a single wall colour , it is best to opt for very thick brushes, as it will facilitate the work. Instead, to draw, it is preferable to opt for finer brushes that allow developing all kinds of details. Certain intermediate brushes, meanwhile, are suitable for various tasks.
