engobe - A colored slip used in decorating ceramics. They have several distinctive attributes, but are also excellent alternatives to glazes because they are less expensive and less time consuming. Engobes are typically made by mixing water with a claybody in use, then mixing in one or more colorants (e.g. oxides) in a proportion of dry ingredients to water that is about 1:2 by volume. They are best applied in a consistency like cream to leatherhard greenware, or a little thinner when applied to bisque. Colored slips stay put they won't run or blur as many glazes do. Textures made in colored slip will remain as they're formed, instead of smoothing out as do those made with glazes. They can be applied with a brush, a slip-trailing bottle, or by dipping or spraying. Another method for using engobes in making a design is called sgraffito: coat unfired clay with engobe, and then scratch away at parts of it to reveal the clay surface underneath.

enlargement - A larger version of an image or of a work. Making an enlargement is sometimes called a bump up or a blowup.

Enlightenment - Also called the Age of Reason, the name applied to an intellectual movement and zeitgeist which developed in western Europe during the seventeenth century and reached its height in the eighteenth. The common element was a trust in human reason as adequate to solve the crucial problems and to establish the essential norms in life, together with the belief that the application of reason was rapidly dissipating the darkness of superstition, prejudice, and barbarity, was freeing humanity from its earlier reliance on mere authority and unexamined tradition, and had opened the prospect of progress toward a life in this world of universal peace and happiness. In the visual arts, this was the time of the Baroque period.

An image of the Enlightenment:

This is a gathering of the members of the Society Dilettante, an exclusive club of British aristocrats dedicated to studying classical art and knowledge on the Grand Tour and as a pastime. As the men enjoy a drink together, Sir William Hamilton (1730-1806), a prominent collector, shows them one of his ancient Greek and Roman vases and a recently published book of engravings of his vase collection. The members are, left to right: Sir W.W. Wynn, Sir J. Taylor, Mr. Payne Galway, Sir William Hamilton, Mr. Richard Thompson, Mr. Stanhope, and Mr. Smith of Heath.

Born to an aristocratic Scottish family, Sir William Hamilton was an enthusiast of the arts and sciences at the height of the Age of Enlightenment. He assembled one of the world's finest collections of Greek and Roman antiquities as British Envoy Extraordinaire to the two Sicilies from 1764-1800. Most of the antiquities he collected came from excavations in Italy, and he later sold most of them to the British Museum. The glories of his vase collection were recorded in portfolios, which served as souvenirs for the great libraries of Grand Tour travelers and patrons, and provided inspiration to decorative art designers in England, such as Josiah Wedgwood (1730-1795). See dilettante.

Also see cinema, dance, kitsch, popular culture, superficial, and theater.



enthusiasm - Great excitement for or interest in a subject or effort, or the source or cause of such great excitement or interest. An enthusiast is an enthusiastic person. Enthusiasm is an important ingredient in motivation to produce art, as well as to study and enjoy it in other ways. It is a quality that springs from the personality of artists, teachers and other lovers of art. Instructors develop their students' enthusiasm most effectively by demonstrating it. So much of school life is routine and mundane that teachers and students can slip into a business-as usual rut. But enthusiasm in the classroom is the spice that brings new zest to learning for teachers as well as for students.

Some strategies for educators:

  1. Plan special events that break the routine. For instance, rearrange furniture, change displays, reassign seating, change procedures, go on field trips, use new teaching techniques, media, etc.
  2. Employ motivational statements that sell the value of the subject matter. For example, "I've got a great work of art I know you'll find interesting right now. I want you to think about what TV show it reminds you of! And, who does this remind you of Tom?!"
  3. Speed up your physical movements in the classroom. Be in a hurry to get on-task. The loss of engaging activity at the beginning of most classes is a motivation damper.
  4. Enjoy your work and let your students know you enjoy it, not only by being enthusiastic yourself, but by directly stating it often.

entropy - The tendency of all matter and energy in the universe including all systems, societies, etc. to change toward a state of disorder or randomness. The works of earth artists Robert Smithson (American, 1938-1973), for example — reflect an interest in the concept of entropy. Related to this is the use of the term in information theory, where entropy is a measure of the apparent disorder of a system, so that the more there is known about it, the less entropy it seems to have. In this vein, entropy is understood as the number of possibilities, which decreases as knowledge grows.

eraser - A tool used in the erasure of parts of drawings. Graphite pencil drawings are erased with any of several types of rubber. (It was after this use that the substance called rubber received its name.) Lighter parts of charcoal drawings can be erased with either a kneaded eraser (also called putty rubber) or a kneaded piece of fresh bread. Wax crayons and lithographic crayons cannot be erased unless they are on non-absorbent surfaces.

Also see canvas scraper, clean up, palimpsest, solvent, and stain removal.



erasure - Removal, usually of written or drawn marks by erasing — rubbing, blotting, wiping, or scraping. The goal of erasure is typically to remove all traces of something, although one finds it practical to compromise at partial erasure. And, the scrambling of material recorded magnetically, as in the use of the delete key on a keyboard.

Erasure is a subtractive redactedgesture.

Additive gestures that obscure place material above the surface to be altered. Also see coat, collage, cover, decollage, distort.

To redact is to conceal (text) from a document prior to its publication or release. Redacting is usually accomplished by covering sensitive areas with opaque pigment, or by removing these areas with scissors or knife. Here's an example: F.B.I. Director Robert S. Mueller met with Attorney General John Ashcroft on March 12, 2004, to ask if Ashcroft would approve a controversial domestic spying program for US President George W. Bush. Later, Mueller wrote some notes about the meeting. Months later, when these notes were to be published, they were extensively redacted. see thumbnail to rightA photo of that document.

erotica and erotic art - Erotica includes images, books, and objects that cause or celebrate sexual feelings or desires. Just as "beauty is in the eye of the beholder," some observers will perceive erotica as obscene or pornographictransgressive. But when sexually suggestive or explicit materials are deemed erotica or erotic art, they are described more neutrally or positively than they are when called obscenity or pornography.

Either way, such subject matter is typically deemed inappropriate for students who are younger than those at the college level.

ethnic - Relating to sizable social groups sharing a common and distinctive racial, national, religious, linguistic, or cultural heritage. "Ethnic" was once a term for Egyptian, African, Mesoamerican, and other non-Christian ("heathen") peoples, even though European cultures posess all the exoticism, inscrutability and "otherness" that "ethnic" implies. European, like ethnic arts, are the products of specific times and places, beliefs and taboos, produced to serve ritual ends, religious and social, confer prestige, and provide cultural self-affirmation. Also similarly, European art evokes complex, sometimes conflicting reactions, admiration, bafflement, amusement, and disdain. "Ethnic" (like "primitive") should therefore be used very cautiously. Considering how profoundly we have needed to reevaluate our uses of "ethnic" to designate non-European peoples, a contemporary use is likely to smack of negative stereotype and ethnocentrism.

exquisite corpse or cadavre exquis - Aleatoric techniques for producing either visual or literary art devised by surrealists in which several people collaborate in creating a text or an image. This activity is often called a game, and the product of this activity are also called an exquisite corpse or, in the original French, cadavre exquis. This game is based upon an old parlor game in which players take turns writing on a sheet of paper folded it to conceal part of the writing, and then pass it to the next player for another contribution.

The surrealists' version of the game acquired its name from the results of the first use of the technique. This was a sentence in French: "Le cadavre exquis boira le vin nouveau," meaning "the exquisite corpse will drink the young wine." The first works were sentences, and were first produced in the mid-1920s. Later literary works were typically poetry. These bizarre compositions were explained by Nicolas Calas as revealing the "unconscious reality in the personality of the group."

Surrealism was embraced by practicioners of many arts, and so it was inevitable that visual artists would take it up, first to produce drawings and collages. The first such efforts, reminiscent of children's books that allow the making of pictures with multiple pages divided at various levels, involved assigning a section of a body to each player. Most resulted in images that only vaguely resembled the human form. Some of the participants in early exquisite corpses were Yves Tanguy (French, 1900-1955), Joan Miró (Spanish, 1893-1983), and Man Ray (American, 1890-1977). Later adaptations have involved using other means of passing the work around, such as sending it through the mail; or using other media, resulting in sculpture, film, digital, etc.

extrude, extrusion - To extrude is to form the shape of an object by forcing plastic media (a "blank") such as clay, wax, plaster, or dough through a die. Extrusion is the process of forming three-dimensional shapes in this way; or it is any product of this process. Lucky Charms cereal

Some pipes, tubes, and other objects are manufactured by extrusion, as are such culinary products as certain breakfast cereals (see thumbnail to leftLucky Charms®), pastas, cookies, and candies. Bakery workers often decorate cakes by extrusion — squeezing or "piping" frosting from conical bags with variously shaped openings at their tips.

Hasbro's "Fun Factory" is a tool for extruding Play-Doh® through strips of plastic dies. Play-Doh is a modeling compound with similar physical properties to clay, but it is not actually ceramic.

Once a pug mill has mixed water with dry clay, it extrudes the product through a round or square opening. Viewers are apt to compare such extrusion to excretion. (Such observers may be indiscrete [infantile?!], diverting attention from loftier goals, but excrement is a product ubiquitous to creatures with digestive systems.) One crucial extruding plasticdifference between these processes is the greater potential in extrusion for varying the shape of the product.

see thumbnail to leftHere's a large machine (an extruder) that is extruding a gray plastic.

Although wire is formed by pulling ever-thinner strands of metal through dies, this action is typically termed drawing rather than extruding.

More liquid media — paint, glaze, and slip — can be applied by forcing it through small holes, using a squirt bottle, syringe, or spraying device perhaps, but its formation is unlikely to be termed extrusion. A resulting markdot, line, wash, mist, whether dragged or smoothed across a surface — will be largely two-dimensional.

An eyedropper can be useful in floating oil colors on water in the marbling of paper. Eyedroppers are very inexpensive, and can be readily obtained from phamacies called chemists in many countries. Glass eye droppers are generally preferable to plastic ones unless safety is an issue.
