cadmium - A metal found in several compounds: cadmium oxide, cadmium carbonate, cadmium chloride, cadmium sulfate, and cadmium sulfide. In paints, inks, enamels, glazes, and dyes, and POISONOUS!permanent pigments (reds, oranges, and yellows) are prepared from cadmiums, mostly cadmium sulfate. It is also used in electroplating, in solder for aluminum, as a constituent of easily fusible alloy, as a deoxidizer in nickel plating, in process engraving, and in nickel-cadmium batteries. Cadmiums are toxic.

The following chart describes six different types of ceramic glazes, each carrying levels of concerns about cadmium, in order to help you to determine which are safe to use on dinnerware vessels for food or drink.

 

1. Dinnerware safe. Contains no cadmium.

2. Dinnerware safe. Contains some cadmium, but passes release tests.

3. Contains cadmium. Not recommended for surfaces which contact food or drink.

4. Contains no cadmium. Not recommended for food because of soft nature of the glaze.

5. Contains no cadmium, but does not pass lead and cadmium release due to soft nature of the glaze.

6. Contains cadmium bearing ingredients. Glaze not recommend on surfaces that contact food or drink.

A sculptor can take an exact measurements from a model with a caliper. Inverted measurements, as well as scaled enlargements and reductions can be obtained with calipers. see thumbnail to leftThese are proportional calipers. By tightening a wing-nut one can establish a vertex anywhere along the central section of this caliper's length. They can enlarge a measurement up to 5 times, or reduce one to as much as 1/5, from measurements taken from either an inside (negative) space or from a positive space.

camera animation of an early movie camera -- its crank turning

 

camera lucida - A device much like an opaque projector, which replaced it, using a prism (lens) and mirrors to project the image of an external object onto a flat surface so that its image may be traced. Replacing the camera obscura, it was invented in the seventeenth century, but not widely used until the nineteenth. Literally, "lighted room." Artist David Hockney (English, lives and works in USA, 1937-) theorized in 2001 that many more artists than have previously been acknowledged — Jean-Auguste-Dominique Ingres (French, 1780-1867) for instance — used camera lucidas (and other lensed devices), causing some controversy over whether this is true, and whether it was in any ways unethical.

Also see copy, likeness, mirror, pinhole camera, Realism, representation, simulacrum, and simulation.

 

 

camera obscura - The origin of the present day camera. In its simplest form it consisted of a darkened room or box with a small hole through one wall. Light rays could pass through the hole to transmit an inverted image of the scene outside the room onto a flat surface on its inside. It was first mentioned by Aristotle in the fourth century BCE, and employed through the centuries as an aid to drawing. These are Latin words, literally meaning "dark room."

Examples:

French, about 1750, Théâtre de l'univers (Theater of the Universe), a portable camera obscura built into a folio binding stamped Théâtre de l'univers, made with wood, metal, and glass; open: 22 1/8 x 21 3/4 x 14 3/8 inches; Getty Research Institute, Werner Nekes Collection, Malibu, CA. See theater.

 

 

 

 

see thumbnail to rightAbelardo Morell (American, born Cuba, 1948-), Light Bulb, 1991, photograph of a corrugated cardboard box, fitted with a lens, so that light from a light bulb beside it is cast onto a wall of the box's interior. Morell has made numerous photographs of rooms that he has transformed into camera obscuras. See transformation.

 

Also see camera lucida, lens, mirror, pinhole camera, projection, projector, sight, and theater.

 

 

camera-ready - In graphic design, two-dimensional artwork that is ready be given to a person who will photograph it so that printed versions can be produced. Although a physical image or piece of copy is still sometimes produced, and is employed in this process, digital imaging has largely eliminated this step. When a camera is needed, copy is considered camera-ready when it is in its final version, clean, flat, and either dark ink on paper or a pasteup. Also see image capture.

 

 

camouflage - The means, effect, or act of concealing someone or something — making a person or thing indistinguishable from his or its surroundings. Also, deception, and disguise, usually for either aesthetic or defensive reasons. Numerous living things owe their species' evolutionary success to camouflaging aspects of their appearance. Humans have employed camouflaging colors, textures, materials, or patterns in the design of numerous artifacts in order to conceal them. This is in some ways the opposite of emphasis, a kind of simulation of transparency or erasure. Modernist architect Frank Lloyd Wright (American, 1856-1959) often built with materials found on a building's site to increase the degree to which it would blend into its environment — to make it less visually intrusive. Costumes designed to reduce the visibility of hunters and soldiers are among the most overt human applications of camouflage, each style intended for use in specific environs. It was in the late 19th century that military uniforms began to be designed to make soldiers appear drably inconspicuous. Before that time, uniforms were typically bright and bold. Since the late 20th century, camouflage fabric patterns have been chosen increasingly for reasons other than concealment. Sometimes, ironically, camouflage designs have been employed in persuit of fashion — to make their users stand out.

camp - Those parts of popular culture commonly considered kitsch, artificial, vulgar, or banal, but which acquire contemporary appreciation, especially which are the most artificial and exaggerated. The things enjoying the attention of camp taste include many old movies, 1950s furniture designs, 1960s fashion, cross-dressing, and drag cultures. The camp sensibility arose simultaneously with the development of Pop Art in the early 1960s, when low art objects became high art's subjects.

Also see brummagem.

 

 

campanile - In Italian architecture, a bell-tower, usually near, but rarely attached to, a church. Sometimes they were connected by cloisters to a church. They were first a product of the Romanesque period in Italy. Campanili (the plural form) in northern Italy are often civic monuments rather than parts of church complexes, were symbols of power, and also served as watch-towers.

(pr. CAM-pə-NEE-lə)

Examples:

 

 

 

 

see thumbnail to rightBecause it is about 12º away from vertical, this campanile is commonly known as the Leaning Tower of Pisa. Built in 1174, this tower has eight stories of arcades, with a diameter of 52 feet, its original height was 151 feet 3 inches. The belfry — atop the tower — was added in 1350. Much work has been done recently to arrest this campanile from leaning further. See dot and perpendicular.

candela - A unit of luminous intensity equal to 1/60 of the luminous intensity per square centimeter of a blackbody radiating at the temperature of solidification of platinum (2,046 K). Also called candle.

 

 

candelabrum - A candle holder or lamp with several arms or branches. The Hebrew word "menorah" means a "holder of light" or candelabrum. The plural form is candelabra.

Example:

cane and caning - A natural, fibrous weaving material used in the production of baskets and chair seats, and in wrapping the joints of wicker furniture. Cane is cut into long strips from the inner layer or skin of the rattan plant. Various widths are available. Stains do not penetrate cane well, and paints don't adhere well either. Fortunately cane has a naturally occurring glossy finish, making varnishes unnecessary.

In glass, a cane is a thin, monochrome rod, or a composite rod consisting of groups of rods of different colors, that are bundled together and fused to form a polychrome design that is visible when seen in cross-section, as in millefiori.

Examples in the fibrous sense:

This was developed from a 1924 design for a cantilevered chair by Mart Stam. It was introduced by Mies van der Rohe at the 1927 Stuttgart exhibition and has remained in production ever since. Mies van der Rohe was the last director of the Bauhaus design school in Dessau, from 1930 until its closing in 1932.

canon - In art, the body of unquestionably important artists (DWMs dead white males) and works. Until recently the canon was seldom challenged, and changed at a sluggish pace. Now it's being relentlessly challenged by art historians and critics recovering forgotten and ignored artists (especially by women, non-whites, and outsiders) both within and outside the Western world. The scope of what is considered art has been widening as new fields, including photography, performance art, video, crafts, and design, are added to what amounts to an ever-increasing canon. Postmodernism, however, has put in question the very idea of an irreducible list of masters and masterpieces. So, when referring to the canon today, one should specify what sort of canon one means.

 

 

canopic jar - An ancient Egyptian vase, urn, or jar used as a container for an embalmed human organ.

The carving is thought to be a specific member of the Egyptian royal family. The massive wig of layered curls is a headdress favored by Akhenaten's queen, Nefertiti, their six daughters, and a minor queen, Kiya. The jar was found in Thebes in a tomb in the Valley of the Kings that has aroused a great controversy concerning the events surrounding Akhenaten's death and succession.

canvas - Commonly used as a support a swatch of canvasfor oil or acrylic painting, canvas is a heavy woven fabric made of flax or cotton. Its surface is typically prepared for painting by priming with a ground. Linen — made of flax — is the standard canvas, very strong, sold by the roll and by smaller pieces. A less expensive alternative to linen is heavy cotton duck, though it is less acceptable (some find it unacceptable), cotton being less durable, because it's more prone to absorb dampness, and it's less receptive to grounds and size. For use in painting, a piece of canvas is stretched tightly by stapling or tacking it to a stretcher frame. A painting done on canvas and then cemented to a wall or panel is called marouflage. Canvas board is an inexpensive, commercially prepared cotton canvas which has been primed and glued to cardboard, suitable for students and amateurs who enjoy its portability. Also, a stretched canvas ready for painting, or a painting made on such fabric. Canvas is abbreviated c., and "oil on canvas" is abbreviated o/c.

canvas scraper - A tool used to scrape oil or acrylic paint from a canvas. A canvas scraper has a curving blade so that its effect is evenly distributed, avoiding cuts and grooves.

 

 

 

capital

 

 

capital letter - In typography, uppercase letters (A, B, C, D, E, F, G, H, etc.) In c. 114 CE, an inscription was chiseled into the base of a column in Trajan's Forum, Rome. That inscription had most of the capital letters known today. Until the sixth century, all inscriptions were in capital letters. And to this day we continue to use them in various ways — for the first letters of important words in titles, proper nouns, etc. They got their alternative name — uppercase — from the standard location in which typesetters stored them. Though visually powerful, whole words written in capital letters should be used sparingly, because they are difficult to read, and may suggest shouting.

A design composed of one or more letters, typically the initials of a name, used as an identifying mark, can be a monogram, and might be used as a logo (also known as a logogram or logotype). An oversized ornamental capital letter used in printing may be called a factotum. One designed with representation that carries narrative qualities may be termed historiated.
