what is paint made out of ?Paint can be made out of many things . But all paints include a pigment, binders, solvent, and a wide range of additives.The pigment is the thing that gives paint its colour.The binder is the part that causes the paint to form a film.The solvent helps to control the flow and application.The additives can help to modify the paint in many ways .

1- pigment: Are used for colouring paint , Ink , Plastic , Fabric , Cosmetics , Food, and other materials. Most pigments used in manufacturing and the visual arts are dry colorants usually ground intro a fine powder. This powder is added to a vehicle (or binder) a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion.A substance used as a coating to protect or decorate a surface ( especially a mixture of pigment suspended in a liquid) dries to form a hard coating artists use paint and pigment interchangeably.

2_ Binder: the nature of oil paint is such that particles of pigment are coated and suspended in a liquid . Which in turn will bind those particles together when exposed to air .That liquid may be a drying oil a resin_oil blend , an oil_modified alkyd resin, One of the new water mixable drying oils. Oil paint in a stick form , primarily wax and pigment will be discussed in the chapter on drawing materials.

3_ Solvent : Solvent are used in paint manufacture to dissolve the different compounds used in the paint formulation such as colour and binder, making the paint the correct consistency fore application . Once the paint has been applied the solvent evaporates allowing the resin and pigment to produce a film of paint and to dry rapidly. With out solvent it would be impossible to produce durable, decorative and in particular, glossy paint for use both indoors and outdoors to with stand all conditions

Three types of paint .......1: Watercolour2: Oils3: Acrylics

Page 7: Paint

Acrylic: is the fast drying paint containing pigment suspension in acrylic polymer emulsion. Acrylic paint can be diluted with water, but become water resistant when dry . Depending on how much the paint is diluted ( with water) or modified with acrylic gels, media, or pastes the finished acrylic painting can resemble a watercolour or an oil painting or have its own unique characteristics not attainable with other media .

Watercolour: Is a painting method . A watercolour is the medium or the resulting artwork in which the paint are made of pigment suspended in a water soluble vehicle. The traditional and most common support for watercolour painting is paper other support include papyrus, bark papers, plastics, vellum or leather, fabric, wood and canvas. Watercolours are usually transparent and appear luminous because the pigments are laid down in a relatively pure from with few fillers obscuring the pigments colour.

Oils paint :Oil paint is a type of slow drying paint that consists of particles of pigment suspended in a drying oil commonly linseed oil. The viscosity of the paint maybe modified by the addition of a solvent such as turpentine or white spirit, and varnish may be added to increase the glossiness of the dried oil paint film. Oil paint have been used in Europe since the 12th century for simple decoration but were not widely adopted as an artistic medium until the early 15th century. Common modern applications of oil paint are in finishing and protection of wood in building and exposed metal structures such as ships and bridges. Its hard wearing properties and luminous colours make it desirable for both interior and exterior use on wood and metal. Because of iuts slow drying properties it has recently been used in paint on glass animation.
