pneumosparklyosis - A fictitious ailment also known as glitter lung.

 

pochade - A small color sketch, usually in oil paint. A pochade is often a rough little landscape, typically produced away from the studio, with the intention of referring to it later in the studio in order to paint a larger, more developed version. A pochade box is a sketch box, a very portable container for carrying oil-painting supplies on field trips. This is a French word used by English speakers.

Also see alla prima, plein air, and underpainting.

 

 

pochoir - A print made from stencils. It was often used for the reproduction of original color works. It was used in France by the most prominent artists and craftsmen to produce illustrated deluxe portfolios, books, limited-edition journals, and decorative and fine-art prints between 1895 and 1935.

point - While it usually refers to a specific location, to a sculptor, a point is a simple metal tool with a pointed end used to rough out (dress) the basic shape of a stone carving. Hammered vertically and with force at the stone face, it not only punctures the stone's surface but causes a rough circle of stone to burst off around this puncture. Handled softly it can gradually reduce the surface, giving it an overall crumbly or pulverized appearance. A fine punch can also be driven into the stone as a defining hole. In addition, the point can be used obliquely to score the stone in long jagged lines. In typography, it is the smallest unit of measurement: although actually .01384 inch, for practical purposes, it is 1/12 of an inch, and twelve points equal one pica.

pointillism - A method of painting developed in France in the 1880s in which tiny dots of color are applied to the canvas. When viewed from a distance, the points of color appear to blend together to make other colors and to form shapes and outlines. Georges Seurat (French, 1859-1891) was its leading exponent. His most famous painting is see thumbnail to rightA Sunday Afternoon on the Island of La Grande Jatte (Un dimanche après-midi à l'Ile de la Grande Jatte), 1884-1886, oil on canvas, 81 x 120 inches, Art Institute of Chicago. Occasionally used synonyms for pointillism have been "divisionism" and "confetti-ism." See other examples at Neo-Impressionism.

Also see brindled, optical mixing, pattern, piebald, Segantini stitch, stipple, and variegated.

 

 

pointing and pointing machine - A mechanical means of indirect carvingreproducing or scaling up a three-dimensional form in correct proportion. A pointing machine is a framework of metal arms which can be fitted around a sculpture to measure the relationship between given points on its surface. A pointing machine permits these measurements to be transferred from a model to another mass of material — usually a block — the block then cut into either by hand or by machine. Pointing machines are especially necessary for the carving of sculptures having complex form which is based on a plastic model. Greek and Roman sculptors are known to have used them. They were re-invented during the Italian Renaissance. Further improvements made during the eighteenth and nineteenth centuries included pantographic devices which allowed small models to be scaled up. The pantograph is a similar device for copying two-dimensional figures.

point of view - A position or angle from which something is observed or considered, and the direction of the viewer's gaze; a standpoint which is either a physical location or one in the mind. Examples of the points of view possible in a picture are: from below, from inside, from outside, from above, and so on. A manner of viewing things; an attitude. The attitude or outlook of a narrator or character in a piece of literature, a movie, or another art form. In discussing art, to use the common synonym "perspective" may be confusing.

Examples of points of view:

 

 

see thumbnail to leftMesopotamia, Palace of King Ashurnasirpal II of Assyria, Nimrud, entrance to the east suite, One of a Pair of Lamassu, c. 875 BCE, carved stone, British Museum, London. However it is displayed in a museum, in its original context, a lamassu is the guardian of a doorway, integral with a wall. For this reason, it is not an entirely freestanding sculpture. It was carved as if it were two reliefs joined at right angles. These guys always have five legs, because that's the way lamassu can present the correct number of legs when seen from each of the two points of view implied by two relief sculptures — two legs when seen from the front, and four when seen from the side. See a larger detail of the legs. Additionally, the side view shows legs in motion, whild the frontal view shows the creature at rest. See Mesopotamian art.

 

 

 

see thumbnail to rightDiscus Thrower (Discobolus), Roman copy of an original bronze by Myron (Hellenistic Greek, c. 485 - c. 425 BCE), marble. In viewing two- and three-dimensional works of art, it is particularly important to see a freestanding sculpture from more than one point of view.

This little party is visiting the studio where Velázquez stands before his canvas. We see the back of it, perched upon an easel. The painter and most of the others look toward the king and queen as they pose for the painting in progress.

 

see thumbnail to leftThe king and queen would not actually be visible in this picture if their reflected image could not be seen in a mirror placed on the opposite wall. Altogether this is a view that could only be seen by the king and queen themselves, as they pose for their portrait. The point of view of every person who gazes upon this painting is that of the king and queen of Spain -- a very privileged vantage indeed! See Baroque, genre, self-portrait, and Spanish art.

POISONOUS!

poison - Any substance capable of causing injury or death. When someone has been exposed to toxic substances, immediately contact a poison control center network or get medical assistance telephone 911 in many communities.MEDICAL ALERT!


Many manufactured art and craft materials carry a label stating "Conforms to ASTM D-4236." This indicates that the product conforms to the labeling standards of the Hazardous Art Materials Act (HAMA), which was signed into US law on November 18, 1988. If the product is non-toxic, then no warning needs to be included on the label. However, if the product is found to carry acute or chronic health hazards, the information on the label must alert the consumer to those hazards. The part of this law which is of greatest importance here is the Labeling of Hazardous Art Materials Act (LHAMA). The law requires art material labels to (a) carry a warning statement identifying chronic health hazards, (b) list the ingredients causing those hazards, and (c) provide directions for safe use of the product. The phrase, "Conforms to ASTM D 4236", is required as evidence that the guidelines of the standard were followed in the labeling of the product. The evaluation is to be conducted by a board-certified toxicologist, and the product must be reevaluated periodically, at least every five years. Another key piece of information to be found on the label, as directed by the standard, is a source for additional information. This can take the form of a toll free phone number that is reachable 24 hours per day, or directions to contact a poison control center network. Under the Labeling of Hazardous Art Materials Act, it became a requirement for chronically hazardous products to carry the phone number of a person responsible for placing the product on the market. The Consumer Product Safety Commission (CPSC) is the US's federal agency charged with enforcing HAMA.

Polish art

 

 

 

polish - To impart a very smooth finish to a surface, or such a finish itself. Also, the material which can be used to produce such a finish, either by rubbing with a mild abrasive or by the action of chemicals. Examples of such materials include: tripoli, rottenstone, pumice, and rouge.

political correctness, politically correct, and PC - Developed in the mass media, these terms came into use in the 1980s to describe those who seek a social transformation in various ways: challenging the canon to which the traditional curriculum had adhered (demanding the inclusion of studies of non-mainstream cultures), traditional notions of identity (race, gender, class, and sexuality), as well as sensitivity to unconscious racism and sexism and to environmental concerns. The momentum of this movement came largely from the political left, and from intense debates taking place on college and university campuses. Although there is no defensible ground on which to disagree with its spirit, this movement has been derided as a form of thought-police for its demands of adherence to a party line.

polyester resins - Synthetic plastic resin in liquid form are made to solidify by the addition of a catalyst. Resin, reinforced with glass fiber, is commonly used as casting material, but may also be modeled when thickened with an inert filler such as powdered chalk. It can be cut and abraded when hard.

Polyester is also a common name for the plastic polyethylene terephthalate. Its characteristics include transparency, colorlessness, and high tensile strength. In addition, it is useful in art conservation because it is very chemically inert. Commonly used in sheet or film form to make folders, encapsulations and book jackets. Its thickness is often measured in mils. There are several common trade names.

polyhedron - A three-dimensional figure bounded by polygons. Each of its sides is called a face. Each of the straight lines which describe the meeting of faces is called an edge, and each point at the end of an edge is called a vertex. The plural form can be either polyhedrons or polyhedra.

Polyhedra are among the ten classes of patterns.

Art employing polyhedra:

Fra Giovanni da Verona (Italian), three panels of wood intarsia, 1520: Each conveys the appearance of open cupboard doors -- a trompe l'oeil effect resulting from the use of linear perspective. The first panel: a Campanus sphere, a mazzocchio, and various instruments of the geometer. The second panel: a complex polyhedron which can be constructed by erecting a pyramid of equilateral triangles on each face of an icosidodecahedron. The third: the Campanus sphere again, along with an icosahedron and a truncated icosahedron.

Types of polyhedra:

polymer - A chemical compound made by grouping molecules to form natural or synthetic resins. Acrylic resins are polymers in a thermoplastic or thermosetting form of either acrylic acid, methacrylic acid, esters of these acids, or acrylonitrile, and are used to produce paints, and such lightweight plastics and synthetic rubbers as nylon. Polymer clay, polyurethane, and other materials are made of polymers.

An example of a painting made with polymer colors:

 

see thumbnail to leftFrank Stella (American, 1936-), Raqqa II, 1970, synthetic polymer and graphite on canvas, 120 x 300 inches (304.8 x 762 cm), North Carolina Art Museum, Raleigh. See Minimalism and protractor.

 

 

polymer clay - A modeling material consisting of finely ground particles of colored polymer, often polyvinyl chloride (PVC), held together by a binder to form a malleable clay-like medium. Trademarked brand names include FIMO and Sculpey. In oven-fired polymer clays, finished articles are heated in a domestic oven to fire or fuse or sinter the polymer molecules into a hard, durable object — often jewelry, beads, or small sculptures. Because polymer clays are made of self-colored molecules, making them bleed-proof: different colors do not bleed into each other when placed against each other.

MEDICAL ALERT!Baking any art material in an oven also used for food carries the risk of contaminating food. Use a separate oven that has reliable temperature control and only bake polymer clays to the manufacturer's recommended hardening temperature. Obtain the Material Safety Data Sheet (MSDS) from the manufacturer or supplier, and make sure the temperature of decomposition is not reached. Do not use hardening modeling clays that have DEHP as a plasticizer, because, at this time (2004), the longterm hazards of replacement plasticizers have not been adequately researched. Use polymer clays either outdoors or in front of a window exhaust fan.

polyurethane - Any of various thermoplastic polymers that contain urethane. Polyurethanes can vary widely in their flexibility and rigidity — eraser-soft to bowling-ball-hard. They are typically used in resins, chemical-resistant coatings, elastomers, adhesives, fibers, and foams for padding and insulation. Polyurethanes can be obtained in cast sheets, bars, rods, and tubes, as well as in liquid forms in both water and oil-based formulas.

Urethane is a crystalline compound that is used especially as a solvent, and as the basis for polyurethanes. "Urethane" and "polyurethane" are terms that tend to be used interchangeably to refer to the same set of materials.

Based on their cost and physical properties — their load-bearing capacity, as well as weather, abrasion, impact, wear and tear resistance — polyurethanes have much to recommend them as alternatives to rubber, plastic, wood, metal, and other materials, in applications that have traditionally been filled by such materials, as proven by polyurethane's many uses in industrial situations.
