STYLES
Abstract: To show emotions by the use of color and shape
in the paintings. The abstract style avoids people, animals or places.
Expressionism: To focus more on certain feelings about
a concept, than making the painting look like the source.
Realism: An art that shows things exactly as they appear
in life. The era began in the 18th century.
Primitivism: Art that is painted simple and has amature
characteristics.
Pointillism: The use of small strokes of paint to make
up a picture. As a viewer moves away from the picture, the small dots
blen together and form a picture.
Impressionism: A painting with bold colors that have
lesser details from outdoor subjects.
Glossary
Abrasion: A paint loss
caused by excess friction during improper varnish removal or a varnish
loss caused by friction.
Acid: A class of chemical compounds commonly
used in printmaking and glass etching to eat away unprotected areas of
the surface to create a design.
Acrylic: A family of synthetic resins made by polymerizing esters
of acrylic acids.
Aesthetic: A philosophical
theory as to what is beautiful (esthetic). Concerning or characterized
by an appreciation of beauty or good taste.
Alkyd: A synthetic resin
which is the condensation product of a polybasic acid such as phthalic,
a polyhydric alcohol such as glycerin and an oil fatty acid.
Alla prima: An Italian phrase meaning painted
solely wet in wet and usually, but not necessarily, at a single sitting.
It is used most commonly with reference to oil painting.
Art Deco: A streamlined, geometric style
popular in the 1920s and 1930s, which derived from various avant-garde
painitng styles of the early twentieth-century.
Art Moderne: Extreme modernistic French style
of design that started with the Paris Exposition in 1925. This style is
characterized by straight lines, angles and geometric decorations.
Artist Proofs (prints
& drawings): Prints created by a print publisher for the artist
to review and work with the publisher to make any necessary adjustments
to coloring, tone, darkness, etc, before the numbered edition prints are
printed. Approved artist proofs are signed, numbered and inscribed as
artist proofs (AP). Artist proofs that are not approved by the artist
are destroyed. Artist proofs are considered of higher value than the proofs
in the numbered edition because of their limited quantity.
Binder: The nonvolatile portion of a coating vehicle which is the
film-forming ingredient used to bind the pigment particles together.
Blanching: A term applied to lacquer when
they become partially opaque, cloudy or transparent upon application or
drying. Fast-evaporating solvents may cool the film enough to cause water
condensation, precipitating solid materials.
Blending: Blending is most commonly used
with reference to academic painting to mean the blending together of separate
touches of color for half tones until the graduations of tone and the
marks of the brush are imperceptible.
Blocking-in: Usually refers to the broad
application of masses of light, shade, and color, in the early stages
of a painting. It helped to obliterated rapidly the glaring bright of
the ground.
Bloom: A bluish fluorescent coat which forms
on the surface of some films.
Body: Common term for the degree of viscosity
of a paint or varnish, as "a lot of body" or "not much
body." A practical term used to give a qualitative picture of consistency.

to all colors of the spectrum, including white and black. Color is described
by three properties: hue, lightness and saturation.
(1) Hue (color, character, dominant wavelength): blue, green, red, etc.
(2) Lightness (brightness, reflectance, value): position on the gray scale
between pure black and pure white (3) Saturation (purity, grayness, cleanliness,
muddiness, chroma): purity or intensity of color.
Craquelure: A pattern of cracks that develops
on the surface of a painting as a result of the natural drying and aging
of the paint film.
Crawling: The tendency of a liquid to draw
up and bead on the surface.
Crazing: Fine lines or minute surface cracks
occurring on painted surfaces due to unequal contraction in drying or
cooling.

added to a drying oil accelerates drying or hardening of the film.
Drying oils: Oils which have the property
of forming a solid, elastic surface when exposed to air in thin layers.
The drying oils most commonly used in oil painting were linseed oil, walnut
oil and poppy oil. Examples of non-drying oil unsuitable for painting
are olive oil and almond oil.
Efflorescence: A phenomena whereby a whitish
crust of fine crystals forms on a painted surface. These are usually sodium
salts which diffuse through the paint film from the substrate.
Egg tempera painting: Egg (either whole,
yolk or white) can be used as a pigment binder. Tempera painting was very
popular until the late fifteenth century.
Emulsion: A suspension of fine particles
or globules of a liquid within a liquid.

decorative and protective glassy coatings on metal as well as glassy,
decorative coatings on glass. Enamel has also implied certain organic
coating such as paints or lacquers.
Extender: A pigment which contributes very
little hiding to the system, but does reinforce the film and alter the
gloss.

flies. Fresh specks can be cleaned off with moistened cotton swabs; however,
aged specks can not be cleaned off at all.
Fugitive pigment: A phrase used to describe
a pigment's impermanence and tendency to fade or change color under the
influence of natural effects such as sunlight.
Gesso: Traditionally a lean layer of size
and chalk to form a ground on which to paint.
Glair: Egg white. It is used in egg tempera
painting and as a coating material.
Glaze: 1) To cover paler under painting with
a layer consisting of transparent pigments and excess medium. Traditionally
used to add color to forms modeled in monochrome opaque paint. 2) To impart
a glass-like surface. Aged glaze is very sensitive to solvents.
Gloss: The shine, sheen or luster of the
surface of a coating. Specular gloss: the ratio of reflected to incident
light at specified angles of incidence. Most common are angles of 20,
60 and 85 degrees. See also sheen.
Grime: Surface dirt: a combination of air-borne
soot, nicotine, and cooking grease. Dirt can be in the varnish, on top
of the paint layer, or on top of the varnish.
Ground: A layer of opaque paint applied to
a support to provide a suitable color and texture on which to draw or
paint.
Haze: The dullness of a surface removable
by polishing. It usually results from faulty solvent balance or incompatibility
of ingredients.
Impasto: The texture created in a paint surface
by the movement of the brush. Impasto usually implies thick, heavy brushwork,
but the term also refers to the crisp, delicate textures found in smoother
paint surfaces.
Inpainting: Paint applied over losses only.
This is a technique commonly used by conservators to unify a painting
that has suffered paint loss.
Lacquer: A term which usually indicates that
the material dries by evaporation and forms a film from the nonvolatile
constituents.
Lake: A colored natural or synthetic dye
absorbed onto a semi-transparent base and used as a pigment.
Latex: a generic term describing stable dispersions
of resin particles in a water system.
Leaching: When solvents are applied to a
paint film, solvent soluble compounds are removed and the film becomes
more brittle.
Lean paint: Lean oil color is paint in which
the oil or fat content has been reduced, usually by indirect means such
as diluting the paint with turpentine.
Light fastness: (1) ability to withstand
color changes on exposure to light (2) the relative degree of change or
lack of change in color of materials exposed to the same amount and character
of light.
Lightness: (Brightness, reflectance, value)
Position on the grey scale between pure black and pure white.
Linseed oil: The most popular drying oil
used as paint medium. The medium hardens over several weeks as components
of the oil polymerize to form an insoluble matrix. Driers can be added
to accelerate this process.
Loaded: A painting is said to be loaded when
it is painted thickly, often with a heavy impasto. A loaded brush is one
charged to its full capacity with paint.
Luster: The gloss of a finish.
Medium: The component of paint in which the
pigment is dispersed.

has been made by the combination of an oil and a resin.
Opacity: Hiding power or the degree of obliteration.
Opaque: Impervious to light or not translucent.
Orange peel: A pebbled film surface similar
to the skin of an orange in appearance. It is caused by too rapid drying
before leveling takes place.
Over paint: This paint was not applied by
the artist but applied at a later date. It not only covers the original
paint, but its presence often indicates an excessive alteration of the
image. Over painting is not an acceptable conservation technique.
Paint layer: The paint layer is the actual
layer or layers of color more-or-less opaque applied by the artist in
the execution of the painting.

visible in the infra-red, to x-rays and sometimes to the naked eye.
Pigment: A finely divided, insoluble substance
which imparts color to the material to which it is added.
Polar solvents: Solvents such as alcohols,
ketones, etc., which contain oxygen, etc. These have high dielectric constants.

molecules are linked together by polymerization.
Priming: The application of sizes and/or
grounds to a support to prepare the painting's surface, modify its absorbency,
texture and color.
Resin: An organic polymer in the form of
a crystalline or amorphous solid, or viscous liquid, of wither natural
or synthetic origins.
Retouching: The work done by a restorer to
replace areas of loss or damage in a painting.
