Painterwork accomplishes two things, namely the preservation and the coloration of the material painted. The compounds used for painting, taking the word as meaning a thin protective or decorative coat, are very numerous, including oil paint of many kinds, distemper, whitewash, tar; but the word paint is usually confined to a mixture of and pigment, together with other materials which possess properties necessary to enable the paint to dry hard and opaque. Oil paints are made up of four parts, the base, the vehicle, the solvent and the driers. Pigment may be added to these to obtain a paint of any desired color. There are several bases for oil paint, those most commonly used for building work being white lead, red lead, zinc white and oxide of iron.
