2. 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
.

3. 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.

4. 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.

5. 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

6. Three types of paint .......
1: Watercolour
2: Oils
3: Acrylics

7. 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 .

8. 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.

9. 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.
