is a synthetic paint that is soluble in water and is quick drying. Its versatility ranges from thin wash application to thick impasto. It was first used by artists in the 1940's.
Alabaster is a name applied to a mineral known as gypsum (a hydrous sulfate of calcium). Also called satin spar, it is readily carved, as it is not extremely hard.
a dye or coloring agent derived from coal tar products. Aniline is a major component in the preparation of such dyes, which were introduced to North American Indian peoples ca. 1870.
is a family of synthetic dyes made originally from coal-tar derivative; first synthesized 1857. Earliest known aniline-dyed yarns in Navajo textiles were raveled from commercial cloth and date to the 1860’s. Aniline-dyed, machine-spun yarns were readily available in the Southwest by 1870's, powdered aniline dyes by the 1880's.
practice of affixing figures, such as animals and corn to pottery’s surface
an intaglio technique producing subtle tones areas in stark contrast to lines produced by etching, another intaglio technique. Fine particles of resin adhering to a metal plate act as an acid resist. After the plate is immersed in an acid bath, visually textured areas result instead of lines.
is a shorthand term referencing that all materials utilized in a frame are acid-free or ph balanced to ensure the safety of the artwork being framed.

A granulated mineral, used for printing to achieve a three-dimensional effect.
is a deep depression carved in pottery before firing, characteristic of some Santa Clara Pueblo pottery and less frequently on San Ildefonso Pueblo pottery.
is a paint similar to gouache (opaque watercolor). Casein is in fact a white, tasteless, odorless protein precipitated from milk by rennin and in casein paint, it serves as the paint's binder. According to ArtLex.com, casein is the basis of cheese, and is used to make plastics, adhesives and foods, as well as paint. Artists apply casein paint to paper, as it is too inflexible for use on canvas.
is pouring molten metal into a mold and letting it harden.
classified and numbered book of prints by a particular artist, listing the titles, dates, editions, states and often photographs of all known prints.
A catalogue raisonne is a book citing all the known works by an artist typically arranged in chronological order. The catalogue raisonne lists titles, dates, and often photographs of all known artworks. In many cases, the artwork's ownership and location is cited as well.
is the dark grey residue consisting of impure carbon obtained by removing water and other volatile constituents from animal and vegetation substances. Charcoal is usually produced by the heating of wood or other substances in the absence of oxygen. The resulting soft, brittle, lightweight, black, porous material resembles coal.
is a method of engraving silver or other metals with an awl or other pointed instrument applied to the surface by hand, as opposed to punched or struck with a hammer.
is a technique in printmaking in which an impression is made on a surface at the same time as its opposite side is adhered to a heavier support in the procedure. This permits printing onto such delicate materials as riche paper and linen, allowing the plate to produce finer details in the printed image than would normally be possible.
a lithographic process using several stones or plates—one for each color, printed in register. The result is color prints, to be distinguished from colored prints that have the color hand-applied after printing.
a Latin term, literally meaning "about.” Its usage represents an approximation in dating a work of art, allowing leeway of about 10 years
"Cleavage" is sometimes used to refer to the partial separation or flaking of paint from a canvas, ground, or other layer of paint. Flaking usually reflects a breakdown in adhesion between the paint layer and the support. The problem may be inherent in an an artist's choice of materials or may result from the deterioration of the glue size in the ground. Such conditions are aggravated by seasonal or artificial climate control changes in temperature and relative humidity. The support expands under humid conditions and contracts under dry ones. As a paint film ages, it loses its elasticity and becomes evem more susceptible to flaking, cracking and cupping. (from Art Lex glossary terms online)
class of basket work in which a continuous spiraling foundation is lashed together by whipstitch-like sewing or binding. Coiled basketry can be constructed by spiraling the foundation material in either the clockwise or counterclockwise direction, thus producing a spiral structural configuration, or diaper, on the base of the basket and horizontal corrugations on the body or sides of the vessel. Variations in types of foundation and stitches exist.

A picture or design created by adhering such basically flat elements as newspaper, wallpaper, printed text and illustrations, photographs, cloth, string, etc., to a flat surface, when the result becomes three-dimensional, and might also be called a relief sculpture / construction / assemblage. Most of the elements adhered in producing most collages are "found" materials. Introduced by the Cubist artists, this process was widely used by artists who followed, and is a familiar technique in contemporary art. "Collage" was originally a French word, derived from the word coller, meaning "to paste."
A print made from an image built up with glue and/or other materials.
A photomechanical graphic process used by commercial artists which separates the primary colors in a color picture. A printing plate is then made for each of the colors (yellow, cyan (blue) and red (magenta) and one for black.
Color trial proof
is printed before the bon a tirer. A color trial proof differs from the edition in the color of the ink that is used. These impressions result as colors are adjusted and tried or “proofed”. Color trial proofs record variations in color and in the proofing of a complex color print. There may be many of them, each differing from the other. At the discretion of the artist, these proofs may be signed "color trial proof, "CTP" or they may be destroyed.
is machine spun, usually industrial dyed yarn.
is named after the Spanish word meaning “shell” are round or oval silver disks, which may be stamped with decorative patterns or set with stones. Single conchos are often used for belt buckles or bolo ties. First Phase concho belts are characterized by a diamond slot cut out in the middle of each concho, through which a leather belt was threaded.

is a type of steel that oxidizes naturally over time, giving it an orange-brown color and a rough texture. It has a very high tensile strength, and in spite of its rusted appearance it is actually more resistant to damaging corrosion than standard forms of carbon steel. It has been used by many contemporary sculptors and architects. United States Steel Corporation says "COR-TEN® is a registered trademark of United States Steel Corporation and can only be used for products produced by United States Steel Corporation or its licensees. COR-TEN® Steel has proven to be an excellent product for bridges, primary structural framing and sculpture."

elements of ornamentation such as patterns and motifs that are organized or composed to create order and beauty. Line, shape, size, space, texture, color, balance, rhythm, and proportion contribute to the overall aesthetic effect of a design. Designs may be classified by type, field, layout and composition of patterns or motifs. Types or orientations of design range from naturalistic to representational and geometric to symbolic and abstract. Design field is the background or division of background upon which a design is placed. Layout is the arrangement of a design on the field.
is a form identifying the technique employed in making a print, as well as the inks, paper, drawing materials and the size of the edition.
A technique in which a sharp needle scratches the plate, creating a burn that yields a characteristically soft and velvety line in the final print.
is any colorant fixed permanently to fibers. Synthetic dyes, including anilines, are chemically manufactured native dyes. Native dyes come from natural, non-synthesized animal, vegetable, and mineral sources; vegetable dyes make use of plant materials such as leaves, flowers, fruits, twigs, bark, roots, etc.
pottery or other objects made from fired clay which is porous and permeable. Earthenware is fired at relatively low temperature, may be glazed or unglazed, and is usually but not always buff, red, or brown in color. Red earthenware is a clay given its color by the presence of iron oxide. A clay body based on ball clay is known as white earthenware. Faience, terra cotta, and majolica are examples of earthenware.
is a set of identical prints, sometimes numbered and signed that have been pulled by or under the supervision of the artist and are authorized for distribution.

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.
Epreuve d'artiste (E.A.)
French term for Artist's Proof
is a technique in the intaglio family, where the design is bitten into the plate with acid. Ink collects in those etched lines to produce the design on paper. A plate of polished metal, usually copper, is first coated with a substance that resists the acid's action. A design is drawn through the etching ground, allowing the acid to etch those lines to the degree, depending on the time the plate is exposed to the acid. A moistened sheet of paper is laid on the plate before the plate is run through the press.

is an object, sometimes but not always of stone with zoomorphic properties believed to be the place where spirits dwell. The fetish can be natural or deliberately shaped or carved. Stone fetishes are used in the Kivas of various Pueblos of the Southwest, and replicas or adaptations of them are used in necklaces carved of turquoise or other materials and sold as jewwelry. The Zuni people are particularly well known for carved fetish jewelry.
a semi-rigid element composed of filaments that is flexible enough to be used as a weaving element in the construction of basketry (e.g., beach grass, cattail stem or leaf, etc.).
the finished edge, selvage, or rim of a basket in which the warp elements are turned down, cut off, or bound in one of several ways: 1) clipped off, 2) self-edged, 3) bent at an angle and bound or interwoven, and 4) composite braided, plaited, twined, or coiled applied finish.
is a blemish on a pot caused by the pot coming into contact with a piece of fuel, thus being fired at a higher temperature.
is a heating process by which the pottery vessel is hardened. The traditional technique does not use a kiln, the fuel is simply being piled around the pots and set on fire. A reducing fire excludes fresh air from the center, resulting in pottery that may be black or a gray tone of white. An oxidizing fire allows for a draft of fresh air to permeate to the center, burning the fuel brightly and cleanly, resulting in a red surface or a creamy white, tan, yellow or orange color.
references three-dimensional shape. The form of a basket is limited only by the makers’ abilities and the nature of the structural materials. A basket can be deep with rounded, globular, or flaring side walls (such as a bowl or hat), or it can be flat or slightly concave (such as a plaque or tray). In addition, a basket my have a sharp or constricted shoulder (such as the bottleneck basket, olla or water bottle) A basket's function varies with changes in form.
is usually walrus task and may have a slightly golden tint.
the inner core or structure of a coil in coiled basketry. The three types of coiled foundation are: bundle, rod or splint, and rod-and-bundle. Bundle foundations are comprised of a number of grass stems or other fine materials which yield wide, flexible coils. Rod foundations can be in either stacked or vertical arrangements or in bunched or triangular arrangements. The former creates wide, flat coils while the latter results in narrow, stiff, solid coils. Rod-and-bundle foundations generally have a single rod in the center of a bundle of stems, which results in coils that are thinner and stiffer than the coils with a bundle foundation.
is an operation whose business it is to cast bronze sculptures
is a brownish yellow, patchy discoloration of paper caused by the action of mold on iron salts, which are present in most paper. Foxing usually results from high relative humidity.
is a term used to describe glass that has been fired (heat-processed) in a kiln at a range of high temperatures from 593 °C (1,099 °F) to 816 °C (1,501 °F). There are 3 main distinctions for temperature application and the resulting effect on the glass. Firing in the lower ranges of these temperatures 593–677 °C (1,099–1,251 °F) is called slumping. Firing in the middle ranges of these temperatures 677–732 °C (1,251–1,350 °F) is considered "tack fusing". Firing the glass at the higher spectrum of this range 732–816 °C (1,350–1,501 °F) is a "full fuse".
is a rug style with dominant central panel, usually a diamond or double diamond, and at least one border, dark red, gray, black, and white color scheme; established by early 1900’s named for community in south-central part of reservation.
a specific type of design in which regular lines, angles, and curves predominate, as in geometry. Geometric designs are a specific aspect of abstract designs which also include amorphous or free-form elements depicting natural shapes through exaggeration, simplification and recomvination. Most basket designs appear to be geometric, due to constraints of basket making techniques. But ethnographic and linguistic data often indicate that these designs are actually stylized or representational patterns and elements that depict objects in the natural world.
is a finely powdered mineral substance painted on the surface of a vessel, which melts during firing and forms a more or less glassy coating. The Pueblo Native Americans used this material only for painting the design lines, not for overall waterproofing until as late as 1700. Thereafter, the use of glaze paint was abandoned in favor of carbon or matte mineral paints.
denotes property with small degree of damage described specifically in the report.
is water-based paint made to appear opaque due to the addition of Chinese white pigment.
A soft black mineral substance, a form of carbon, available in powder, stick, and other forms. It has a metallic luster and a greasy feel. Compressed with fine clay, it is used in lead pencils (though contemporary lead pencils contain no lead), lubricants, paints, and coatings, among other products. Also called black lead and plumbago.

are disk shapes of shell or stone, often strung to form necklaces.
is pottery produced after the arrival and influence of Europeans to North America and continuing to the late 19th century.
Hors de Commerce
Translates to "not for trade". These impressions tend to be identical to the regular editioned prints, but their "numbering" shows as "H.C." and were created to use primarily as salesman samples to demonstrate the appearance of a print titled "XYZ" by Miro, Calder, etc. As the number of H.C.'s were not typically documented, those creating fake prints choose to number the spurious prints "H.C."
is paint applied in outstandingly heavy layers or strokes.

was discovered in Germany by Aloys Senefelder in 1798. Printing technique in which the image areas on a lithographic stone or metal plate are chemically treated to accept ink and repel water, while the non-image areas are treated to repel ink and retain water. Because the printing surface remains flat, lithography is sometimes referred to as a planographic technique.
is a method of casting metal by making a wax model, coating it with clay to form a mold, and leaving small holes for the wax to escape when heated. Molten metal is poured into the mold, filling the space left by the "last wax" also called cire perdu.

First invented in 1924 by William H. Mason, it consists of a type of hardboard made from wooden chips. These chips are blasted into long fibers with steam, then they are formed into boards that are subsequently heated to form the finished boards. No glue, resins or other binders are used. In the 1930's and 1940's artists and hobbyists began to use masonite for a painting surface.
is a small village in the state of Chihuahua, Mexico, less than 100 miles (160 km) from the US-Mexico border. The community, population 2,000, is one of the designated localities in the municipality of Casas Grandes, one of several such pueblos in a wide, fertile valley long inhabited by indigenous people. The ancient ruins of Casas Grandes are located nearby. Mata Ortiz has recently seen a revival of an ancient Mesoamerican pottery tradition. Inspired by pottery from the ancient city of Paquimé, which traded as far north as New Mexico and Arizona and throughout northern Mexico, modern potters are producing work for national and international sale. This new artistic movement is due to the efforts of Juan Quezada, the self-taught originator of modern Mata Ortiz pottery, his extended family and neighbors. Mata Ortiz pots are hand built without the use of a potter’s wheel. Shaping, polishing and painting the clay is entirely done by hand, often with brushes made from children’s hair. All materials and tools originate from supplies that are readily available locally. The preferred fuel for the low temperature firing is grass-fed cow manure or split wood. Each of these characteristics derive from the ancient pottery traditions of the region, however Mata Ortiz ware incorporates elements of contemporary design and decoration and each potter or pottery family produces distinctive individualized ware.
is a green building material produced by the US-based Sierra Pine Company. It can be used as an environmentally-friendly substitute for plywood or particleboard in any interior, non-structural application. Medite® is similar to medium-density fiberboard (MDF) in that it is made from finely shredded wood fibers rather than wood chips or sawdust. The fibers are tightly compressed and bound with resin to form a densely constructed sheet of wood.
Material employed by an artist to convey his/her artistic expression.
is an intaglio image-making technique in which the plate is worked from dark tones to light. The surface is first roughened with a mezzotint rocker or roulette so that, if inked, it would print a rich, solid black. The areas that are not to print are then burnished and flatted to produce various grays and white.
is clay containing mica, characteristically used by potters at San Juan, Taos and Picuris.
is a substance used for decorating pottery formed of a finely powdered mineral substance such as iron oxide, mixed with water and perhaps even including some carbonaceous material (as a binder).
is a fine art printing process allowing for the production of deep textured prints with very fine surface detail. The artist begins with any solid material or combination of materials on which he/ she incises, impresses, carves, collages or guilds up a matrix. From the matrix, a sequence of forms are then molded, one from another, resulting in a highly sensitive cast copper printing plate in reverse. The plate is inked using all the colors applicable to that print. Moist paper pulp is then laid onto the surface. Both plate and pulp are forced through the press, while transferring the color to the paper. The plate is re-inked each time a print is pulled. Because of the extreme pressure at which these prints are produced, the ink is absorbed into the paper, giving them a fresco-like quality.
technically a print pulled in an edition of one, from a painting made on a sheet of metal or glass. Frequently referred to as a monoprint as well.

is a general term for paint bound with a drying oil, usually linseed oil, made from pressed flax seed.
is a painting and drawing medium with characteristics similar to pastels and wax crayons. Unlike "soft" or "French" pastel sticks, which are made with a gum or methyl cellulose binder, oil pastels consist of pigment mixed with a non-drying oil and wax binder. The surface of an oil pastel painting is therefore less powdery, but more difficult to protect with a fixative. Oil pastels provide a harder edge than "soft" or "French" pastels but are more difficult to blend.

Technique for the transfer of photographic images to a stencil for screenprinting.
is a problem observed occasionally on Pueblo pottery resulting from expansion and contraction of improperly prepared clay or impure clay.
printing from a flat surface. Visually refers to lithography.
is a building material similar to mortar or cement. Like those materials, plaster starts as a dry powder that is mixed with water to form a paste which liberates heat and then hardens. Unlike mortar and cement, plaster remains quite soft after setting, and can be easily manipulated with metal tools or even sandpaper. These characteristics make plaster suitable for a finishing, rather than a load-bearing material. The term plaster can refer to gypsum plaster (also known as plaster of Paris), lime plaster, or cement plaster.
is a refined stencil-based technique to create prints or to add color to pre-existing prints, most popular from the late 19th century through the 1930's. Originally the stencils were made of thin sheets of aluminum, copper or zinc. Later celluloid or plastic were used to make the stencils from.

Screenprint, Serigraph, Silkscreen
are interchangeable. They reference printmaking techniques using a fine screen made from silk, acrylic or other fiber through which ink is squeezed. The screen acts as a stencil. Each layer of color is residing on top of the paper substrate and is usually opaque. Sometimes the grid from the screen is visible on the top surface of the ink.

is defined as a steel alloy with a minimum of 10.5 or 11% chromium content by mass. Stainless steel does not stain, corrode, or rust as easily as ordinary steel, but it is not stain-proof. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and resistance to corrosion are required.
is a process of decorating silver with punches or stamps. These stamps impress their design into a piece of metal once a hammer is applied to the flat end of the stamp with some force.
During the 1820's steel replaced copper for many types of plate. Steel gives a much harder wearing plate, that could be used for thousands of impressions before signs of wear appeared. Steel also allowed much finer detail to be engraved, which would quickly have worn on a copper plate. However, the task of engraving became much more difficult due to the change in metal, necessitating changes in methods and finer, harder, tools.
A printing process in which an image is cut out of mylar plastic and placed over printing paper. Ink is then stippled through the open parts of the "mask" to produce images in soft, modulated colors.
consists of 92.5% silver and 7.5% copper.
Stipple is a drawing, painting, or engraving method employing dots rather than lines. Stippled works can be produced with any of a variety of tools, including pencils, crayons, pens, and brushes.

a specific type of design in which an object being portrayed is standardized with a motif that falls between naturalistic and representational. Stylized motifs, such as men on Southwest basketry, are often identical in form and manner of execution.
Sugar Lift Aquatint
Dating from the 18th century revived in the 20th century, this technique enables the artist to establish dark areas directly by drawing on the copper plate with a solution of black watercolor and sugar, applied by either pen or brush. After a number of chemical treatments, a dark tone on a white background results.
Sugar lift etching
A sugar lift etching is made by painting on the surface of the plate with a brush dipped in a solution made of sugar and water. Unlike soap ground, which resists acid, the sugar solution must be removed, or lifted, before the plate goes in the acid. After the sugar lifts, the printer applies an aquatint, and the acid bites into the portions that were drawn by the artist with the sugar solution.

Active weft and warp elements characterized plaited basketry (i.e., both weft and warp elements are active in the weaving process). Active weft and passive warp elements are typical of twined basketry.
is made up of yarns that are strung on a loom. Weft yarns are woven over and under the warps. In completed Navajo rugs, the warps are hidden by the wefts.
is any paint that uses water as a solvent. Paintings done with this medium are known as watercolors. What carries the pigment in watercolor (called its medium, vehicle, or base) is gum arabic. An exception to this rule is water miscible oil paints, which employ water as their solvent, but are actually oil paints. British spelling is “watercolour”.
is an image made within a sheet of paper by variations in pulp thickness.
consists of the yarns that are woven over and under the warp yarns, which are attached to the loom. In completed Navajo rugs, only the weft lines are visible.
