GLOSSARY OF ART TERMS

 A -

Abstract Art
Any art in which the depiction of real objects has been subordinated or discarded in favor of patterns, lines and color.
Acid free 
A vague term, referring to a material with a pH of 7 or higher. Sometimes used incorrectly as a synonym for alkaline or buffered material. Some acidic materials are chemically neutralized with the addition of alkaline products; other materials are processed to remove the acid-producing elements. (Acid-free materials may become acidic over time due to residual chlorine from bleaching, aluminum sulfate from sizing or atmospheric pollutants.)
Acrylic Paint
Artists' colors made by polymerizing a methyl methacrylate by emulsification, thus dispersing the resin into tiny particles in water. This fluid is used for a base in compounding polymer colors. Acrylic colors are water soluble when wet, but dry to an insoluble film. Colors are bright, dry quickly and are flexible.
Animation Cel
A clear plastic sheet onto which a drawing is copied, either by hand-inking or by a xerographic copier process. Colored paints are applied to the reverse side. One or more cels may be placed over a painted background, which serves as a setting for the action. In animated movies and cartoons, twenty-four cels are required for each second of screen time. Cel is an abbreviation for Celluloid (trademark).
Archival
Broadly used to describe materials that have the least harmful effects on the art being framed or stored and thus preserving such pieces for the longest period of time.
Artist's Proof
Historically, it was a print retained by the artist for his/her own use or sale. It may bear the designation A/P.

- B -
Batik
Originated in Java; a method of dyeing textiles. Wax is applied to sections of material which are to remain uncolored; the dyes do not penetrate wax. Once dyed, the wax can be removed by various methods, one of which is boiling. Repeated waxing and dyeing results in colorful patterns. The lines typically found in batiks are produced by cracking the hardened wax before applying the dye.

- C -
Canvas
A heavy woven fabric usually of cotton or linen, used as a support for a painting. The surface is prepared for painting by applying gesso or rabbit skin glue. 2) Interlocked or woven fibers used as the ground material for needle art
Cast Paper
Paper made by pressing the pulp into a die or mold used for casting or shaping, becoming a work of art in and of itself.
Cibachrome
A color photograph based on the silver dye-bleach system. The necessary colors (azo dyes) are built into the emulsion layers. These colors are bleached out where not needed during developing. Azo dyes produce more brilliant colors and have greater stability and resistance to light than any other current process. Ilford has renamed its process Ilfochrome.
Collage
Artwork created by securing pieces of paper, fabric or other materials onto a substrate. Though basically two-dimensional, it may have a sculptural effect.
Composition
The arrangement of elements, shapes and colors in a work of art.
Conservation (preservation)
In framing, it is the careful maintenance and protection of works of art. In conservation (preservation) framing, using materials and procedures that will have no adverse effects on a piece of artwork and will protect the artwork from external damage.


- D -
Deckle Edge
The feathery edge of a sheet of handmade paper, caused by the deckle or frame which confines the pulp to the mold. Also present on some machine-made papers, caused by the rubber deckle straps at the sides of the paper machine.
Decoupage
Decoration of a surface by covering it completely with cut out paper forms. The process used in making collages.
Diptych
1) A set of two prints making one complete image. 2) An ancient writing tablet consisting of two pieces of wood or ivory hinged together, with the inner sides waxed for writing on with a stylus.

- E -
Edition
The total number of copies printed from the same plates or blocks and published about the same time.
Engraving
Lines cut into a plate by hand with a steel burin or graver; no acid is used. The metal which is displaced in cutting is smoothed with a scraper which results in crisp, meticulous lines. Then the entire plate is thoroughly inked, with care taken to force the ink down into all of the lines, completely filling them. The surface is wiped clean, leaving the incised lines filled. A press is used to transfer the image onto paper.
Etching
A printing process. A metal plate is covered with an acid-resisting ground. The design is scratched through this ground, exposing the metal beneath. The plate is then immersed in an acid bath, causing the scratched or exposed areas to be eaten away. The plate is wiped clean, inked and the higher surfaces cleaned again, allowing the ink to remain in the incised areas. A press is then used to transfer the image onto paper. (n) Art work so executed.
