absorption

Refers to the light absorbing behavior of some surfaces-- various characteristics determine the degree to which surfaces absorb certain colors. The light which is absorbed is converted to heat, while light not absorbed is either transmitted (by transparency or translucent surfaces) or reflected (by opaque surfaces). Not to be confused with adsorption.

acetic acid

In graphics, a liquid used to clean a plate just before the mordant is applied.

jump to top of page

acetone

A volatile solvent, commonly used with lacquers and in paint-removers; also known as dimethyl ketone and 2-propanone. It is soluble in water and alcohol. It is non-photochemically reactive. One of its uses is to clean up epoxy resins, polyester resins, contact cement, fiberglass, along with many inks and adhesives. Acetone is often used in the cleaning and restoration of old paintings. Because of its toxic and highly flammable qualities, carefully read cautioning labels on containers. (pr. ass"e-tone')

acid dye

A very large class of dyes containing acidic groups, such as the sodium salts of sulfonic acids or phenolic groups. Acid dyes are used in dyeing leather, paper and natural fibers. Their particular value lies in an ability to produce bright, uniform colors.

jump to top of page

acid free

Said of papers with a 7 pH, or very close to 7 pH. Below 6.5 pH or above 8.5 pH is not considered acid-free. Acid-free material are more permanent, less likely to discolor, or to corrupt materials they are placed with over time. Works on paper, and the mats, mounts, etc. with which they are framed, are best acid-free.

acrylic flow improver

A medium used with acrylic paints designed to improve their flow without diminishing the strength of its color.

jump to top of page

acrylic paint

Synthetic paints, with pigments dispersed in a synthetic vehicle made from polymerized acrylic acid esters, the most important of which is polymethyl methacrylate. First used by artists in the late 1940s, their use has come to rival that of oil paints because of their versatility. They can be used on nearly any surface, in transparent washes or heavy impasto, with matte or glossy finishes. Acrylic paints dry quickly, do not yellow, are easily removed with mineral spirits or turpentine (use acetone if those don't remove enough), and can clean up with soap and water.

jump to top of page

acrylic plastics

A range of rigid, lightweight plastics, used commonly in the form of sheets or rods, as well as in their liquid state for casting or coating. Acrylics may be made transparent, translucent, or opaque, and are available in a range of colors. (pr. uh-cri'licks)

jump to top of page

action painting

The style of painting, also called Abstract Expressionism, which developed in the 1940's in New York. Artists splashed, dripped, and drizzled pigment onto the canvases. The term action refers to the activated, gestural brushstrokes evident in a painting's surface.

Example: Painter Jackson Pollock's Full Fathom Five, 1947

adhesion

The act or state of adhering.

See Also:  adhesivesabsorption

jump to top of page

adhesives

Substances, like glue, paste or cement, which cause adhesion, or stickiness. Apply them to clean, dry surfaces. Drying times can usually be reduced by increasing the temperature. 70° F or higher is generally preferred. Use caution with catalysts and solvents, because most are toxic or hazardous. Softwoods require more clamping time than hardwoods. Because they are so absorbent, endgrain surfaces should receive two applicationsthe second only after the first is dry. Clamp joints together whenever possible for increased strength. Applying too much adhesive can weaken a joint in some cases. Follow the directions on the package. Various types include mucilage, rubber cement, hot-glue, epoxy, cyanoacrylic and silicone. Factors determining choice are likely to be: the surfaces to be adhered (porous or nonporous), and needs for strength, toxicity, water resistance, flexibility, temperature range, setting time, and expense.

aggregate

Inert granular material such as sand or gravel which is mixed with cement to make concrete, or with a binder to make some other solid compound. Sand is the most common aggregate. An aggregate might be added to a mixture to add strength, hardness, softness, color, texture, or economy. For instance, to make plaster easier to carve, one can add an aggregate of vermiculite or perlite (both available at gardening stores.)

See Also:  filler

airbrush

A precision spray gun attached to an electric air compressor (or other means of air pressure), or the use of this device to spray paints, dyes or inks. A great variety of spraying effects can be achieved using an airbrush, typically for very smooth applications or gradations of color. The use of airbrush is strongly associated with commercial art, in which it is often used in illustrations, in photographic retouching, and other types of painting. Computer "paint" and photography programs usually have the ability to simulate this painting method.

alabaster

A white or yellowish white translucent stone, which is a type of gypsum found in England and Italy. Its softness makes it easy to carve, but also easily broken, soiled, and weathered. The "alabaster" of ancient Egypt and Rome is actually a much harder stone-- onyx-marble, which is a calcium carbonate, whereas ordinary gypsum is a calcium sulfate.

Example: Sculptor Anish Kapoor's rough forms often are made of alabaster.

albumen print

A paper for making photographic prints, on which egg whites (albumen) coated the paper in order to increase its sensitivity, adding to the brightness of whites in the picture. This process was invented in the mid-19th century by Blanquart-Evrard. Albumen prints were the state of the art in photography from 1855 to 1895, when gelatin provided a more stable effect.

alcohol

A colorless, volatile, flammable liquid, synthesized or obtained by fermentation of sugars and starches and widely used, either pure or denatured, as a solvent and in numerous manufactures as well as in intoxicating beverages. Types include absolute alcohol, ethanol, ethyl alcohol (solvent for shellac and some other resins), grain alcohol, denatured alcohol (inexpensive, because not taxed, and readily available, this is the type artists use most.) Denatured alcohol is ethyl alcohol to which a poisonous substance, such as acetone or methanol, has been added to make it unfit for consumption. Also an alcohol, although from other compounds, is methanol (also known as methyl alcohol, wood alcohol), whose liquid and vapors are highly toxic.

aluminum

A silvery-white, ductile metal, having good conductive and thermal properties, and used to form many hard, light, alloys which are corrosion-resistant due to a protective oxide that forms on its surface. Aluminum melts at 1220°F (660.2°C) and can be cast and welded. It is available in a wide variety of colors, is often used in paints, foil, jewelry, and welding and is used when lightness combined with strength is desired. Aluminum is derived from bauxite. Although bauxite is the most abundant metal in the earth's crust, the processes necessary to creating aluminum were not developed until 1825, and aluminum not used extensively until the 20th century. Atomic symbol Al; atomic number 13; atomic weight 26.98; specific gravity 2.69; valence 3. This metal, known as aluminum in the United States, is known as aluminium in most other countries.

aperture

An opening. In photography, the circular hole in the front of the camera lens which controls the amount of light allowed to pass on to the film. On all but very inexpensive cameras the size of the aperture is variable. The degree of variability is indicated by "f" numbers (f/stop). A great way to gain an understanding of apertures is to make and use a pinhole camera.

applied arts

The arts concerned with making objects with functional purposes, but for which aesthetic concerns are significant. The applied arts may include architecture, interior design, the design of manufactured items, ceramics, metalwork, jewelry, textiles, glass, furniture, graphics, clocks and watches, toys, leather, arms and armor, musical instruments, etc. Commercial art may be considered a branch of applied art. The applied arts are usually contrasted with the fine arts (drawing, painting, sculpture, fine printing, etc.), which are seen as serving no purpose other than providing an aesthetic experience. Most of the applied arts might also be described as design. The distinction between the applied and the fine arts did not emerge strongly until the time of the Industrial Revolution, and accompanied a growing secularization of art and the emergence of a need felt by some artists to replace dying spiritual values with purely aesthetic values, setting art apart from the rest of life. Nevertheless, some have emphasized the importance of craft and regard the distinction between the fine and the applied arts as false and undesirable. Even to those who see it as important to make this distinction, many objects make it very difficult because their purposes are so dominated by their aesthetic ones.

aquatint

An intaglio, etching, and tonal printing process in which a porous ground allows acid to penetrate to form a network of small dots. Aquatints often resemble wash drawings. Any pure whites are stopped out entirely before etching begins, then the palest tints are bitten and stopped out, and so on as in etching. This process is repeated 20 to 30 times until the darkest tones (deepest recesses in the plate) are reached.
