The basic papermaking process takes advantage of the ability of plant cell fibers (cellulose) to adhere to each other when a watery pulp made from the fibers is spread on a screen called a deckle, and dried. Today, paper is made principally from wood pulp combined with pulps from waste paper or, for fine grades of paper, with fibers from cotton rags. For newsprint, tissues, and other inexpensive papers, the pulp is prepared mechanically, by grinding the wood, sometimes boiling it with various chemicals. The pulp is poured onto a deckle, where the water drains away and the fibers begin to mat. The paper layer then passes through a series of rollers that dry, press, and smooth it, and add various finishes.
a pure clay, sometimes called china clay, used in white clay bodies such as porcelain. It is used as a source of silicon
A unit of absolute temperature often used in photography to measure the color temperature of a source of light. Abbreviated K, kelvins can be converted to degrees Celsius by subtracting 273. Certain tungsten lamps are designed to burn at specific absolute temperatures (usually 3200 or 3400 K), guaranteeing that compatible photographic films will render the color they illuminate quite accurately.
A small interlocking device in the seam of a mold, enabling the mold to be precisely reassembled. The term may also refer to the slight roughening of a surface which allows a painted finish to adhere effectively. Also, it's a name given to wedges for canvas stretchers. And in architecture, the keystone at the top of an arch.
Abbreviation for kilogram.
A potter's wheel which is driven by kicking a revolving cement disk. The major alternative is a wheel driven by an electric motor.
An special oven or furnace that can reach very high temperatures and is used to bake, or fire clay. Kilns may be electric, gas, or wood-fired. (pr. kiln or kill)
A refractory mixture, usually kaolin or flint, which is mixed with water and painted on kiln shelves to prevent glaze from adhering.
A unit of weight measurement equal to 1000 grams. To convert kilograms into pounds (US), multiply them by 2.20462. Abbreviated kg.
Expressing movement. In art, kinetic refers to sculpture that moves, such as a mobile or stabile. (pr. ki-ne'tick)
Artwork that includes movement, either mechanical or random. The Constructivists were the first to create kinetic art in the early 20th century, and Alexander Calder worked almost exclusively to make kinetic sculptures.
