Brush 

in painting, drawing, and calligraphy, the principal instrument for applying color to canvas, paper, or other types of support. Brushes are made of animal hair or fur from which the fat has been removed. The hair or fur is then tempered. Stiff bristle brushes (rounded or flat) are used in oil painting. Brushes with longer bristles are used in distemper and fresco painting. Rounded and pointed soft brushes are used in watercolor and tempera painting, as well as in drawing. Brushes made from the fur of the Siberian weasel, which are soft and supple, can be used in any medium of painting.
