Glaze (painting Technique)
A glaze is a thin transparent or semi-transparent layer on a painting which modifies the appearance of the underlying paint layer. Glazes can change the chroma, value, hue and texture of a surface. Glazes consist of a great amount of binding medium in relation to a very small amount of pigment. Drying time will depend on the amount and type of paint medium used in the glaze. The medium, base, or vehicle is the mixture to which the dry pigment is added. Different media can increase or decrease the rate at which oil paints dry. Often, because a paint is too opaque, painters will add a medium like linseed oil or alkyd to the paint to make them more transparent and pliable for the purposes of glazing. While these media are usually liquids, there are solid and semi-solid media used in the making of paints as well. For example, many classical oil painters have also been known to use ground glass and semi-solid resins to increase the translucency of their paint. Oil painting In oil pain ...

Colorfulness
Colorfulness, chroma and saturation are attributes of perceived color relating to chromatic intensity. As defined formally by the International Commission on Illumination (CIE) they respectively describe three different aspects of chromatic intensity, but the terms are often used loosely and interchangeably in contexts where these aspects are not clearly distinguished. The precise meanings of the terms vary by what other functions they are dependent on. * Colorfulness is the "attribute of a visual perception according to which the perceived color of an area appears to be more or less chromatic"., page 87. The colorfulness evoked by an object depends not only on its spectral reflectance but also on the strength of the illumination, and increases with the latter unless the brightness is very high ( Hunt effect). * Chroma is the "colorfulness of an area judged as a proportion of the brightness of a similarly illuminated area that appears white or highly transmitting".

Pointillism
Pointillism (, ) is a technique of painting in which small, distinct dots of color are applied in patterns to form an image. Georges Seurat and Paul Signac developed the technique in 1886, branching from Impressionism. The term "Pointillism" was coined by art critics in the late 1880s to ridicule the works of these artists, but is now used without its earlier pejorative connotation. The movement Seurat began with this technique is known as Neo-impressionism. The Divisionism, Divisionists used a similar technique of patterns to form images, though with larger cube-like brushstrokes. Technique The technique relies on the ability of the eye and mind of the viewer to blend the color spots into a fuller range of tones. It is related to Divisionism, a more technical variant of the method. Divisionism is concerned with color theory, whereas pointillism is more focused on the specific style of brushwork used to apply the paint. It is a technique with few serious practitioners today an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strié
''Strié'' is a popular form of faux painting using glaze and paint brushes to create a soft natural striped texture. Strié is a negative glaze technique. The glaze is generally rolled over the entire surface, and then removed with a tool such as a brush.Phil Schmidt, ''Building & Finishing Walls & Ceilings'', Creative Publishing International, 2002, p86. The word ''strié'' can be used to describe this process of painting, or to describe the actual finish created. Strié is a simple technique that can be altered and elaborated in many ways. It can be done on its own, with the streaks directed either vertically or horizontally. It can be brushed over a raised plaster stencil. It is also very popular to overlap a horizontal and vertical strié, creating the look of fabrics such as linen or denim. This is often referred to as a linen weave or burlap strié.

Rag Painting
{{unreferenced, date=August 2007 Rag painting or ragging is a form of faux painting using paint thinned out with glaze and old rags to create a lively texture on walls and other surfaces. Ragging can be done as a negative or positive technique. The former involves rolling glaze over the entire surface, and removing it with clean rags to reveal the underlying paint color in a pleasing textural pattern. The latter is accomplished by applying glaze directly to the wall with a rag, and creates a similar pattern. Ragging is a very adaptable finish that can be used in a variety of areas, creating the illusion of an old world texture, but on a flat surface that can be easily painted over. Ragging can be done in a variety of patterns, including rag rolling, in which the rags are twisted together and then rolled over a wet glazed surface creating the illusion of fabrics such a velvet or silk. Ragging is also often used as a pattern underneath stenciling. See also * Strie * Color w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Faux Painting
Faux painting or faux finishing are terms used to describe decorative paint finishes that replicate the appearance of materials such as marble, wood or stone. The term comes from the French word ''faux'', meaning false, as these techniques started as a form of replicating materials such as marble and wood with paint, but has subsequently come to encompass many other decorative finishes for walls and furniture including simulating recognisable textures and surfaces. History Faux finishing has been used for millennia, from cave painting to the tombs of ancient Egypt, but what we generally think of as faux finishing in the decorative arts began with plaster and stucco finishes in Mesopotamia over 5,000 years ago. Faux painting became popular in classical times in the forms of faux marble, faux wood, and ''trompe-l'œil'' murals. Artists would apprentice for 10 years or more with a master faux painter before working on their own. Great recognition was awarded to artists who cou ...

Epoxy Glazing
Ceramic fixtures are being more commonly glazed with 2 part epoxy compounds. The first component is a clear or opaque resin combined with a catalyst or hardener. The proper procedure requires that the nonporous fixture be sand blasted to create a rough surface for the epoxy primer to adhere to. Once the primer has dried the topcoat is applied. Since a true epoxy begins to yellow at the age of 1 year acrylic polyurethane compound is used in the topcoat. This resin is also catalyzed with a hardener and can last up to 15 years or more with proper maintenance. Formica ''Formica'' is a genus of ants of the family Formicidae, commonly known as wood ants, mound ants, thatching ants, and field ants.

It is most commonly used to protect, color, or provide texture. Paint can be made in many ... thinned out with glaze to create a subtle wash of color over walls or other surfaces. Color washing gives a surface a translucent, watercolor appearance. It can be used to add texture or accentuate natural surfaces. It can be applied in any color of paint, generally with brushes over a solid paint color, using long sweeping strokes to meld the glaze colors together.

Acrylic Painting Techniques
Acrylic painting techniques are different styles of manipulating and working with polymer-based acrylic paints. Acrylics differ from oil paints in that they have shorter drying times (as little as 10 minutes) and are soluble in water. These types of paint eliminate the need for turpentine and gesso, and can be applied directly onto canvas. Aside from painting with concentrated color paints, acrylics can also be watered down to a consistency that can be poured or used for glazes. Preventing paint from drying out Acrylics are often preferred because they dry faster on canvas than oil paints due to their polymer base. However, in some circumstances, the artist may want the paint to stay moist longer. A trick to keep paints from drying out is to spray a light mist of water over them occasionally. Moisture-retaining palettes also increase acrylic paint drying time, and can be substituted with a shallow container, a sheet of grease proof paper, or piece of wet watercolor paper. Crea ...

Lightness (color)
Lightness is a visual perception of the luminance (L) of an object. It is often judged relative to a similarly lit object. In colorimetry and color appearance models, lightness is a prediction of how an illuminated color will appear to a standard observer. While luminance is a linear measurement of light, lightness is a linear prediction of the human perception of that light. This is because human vision's lightness perception is non-linear relative to light. Doubling the quantity of light does not result in a doubling in perceived lightness, only a modest increase. The symbol for perceptual lightness is usually either J as used in CIECAM02 or L^* as used in CIELAB and CIELUV. L^* ("Lstar") is not to be confused with L as used for luminance. In some color ordering systems such as Munsell color system, Munsell, Lightness is referenced as value. Chiaroscuro and Tenebrism both take advantage of dramatic contrasts of value to heighten drama in art. Artists may also employ shading ...

Glycerin
Glycerol (), also called glycerine in British English and glycerin in American English, is a simple triol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in lipids known as glycerides. Because it has antimicrobial and antiviral properties, it is widely used in wound and burn treatments approved by the U.S. Food and Drug Administration. Conversely, it is also used as a bacterial culture medium. It can be used as an effective marker to measure liver disease. It is also widely used as a sweetener in the food industry and as a humectant in pharmaceutical formulations. Because of its three hydroxyl groups, glycerol is miscible with water and is hygroscopic in nature. Structure Although achiral, glycerol is prochiral with respect to reactions of one of the two primary alcohols. Thus, in substituted derivatives, the stereospecific numbering labels the molecule with a "sn-" prefix before the stem name of the m ...

Linseed Oil
Linseed oil, also known as flaxseed oil or flax oil (in its edible form), is a colourless to yellowish oil obtained from the dried, ripened seeds of the flax plant (''Linum usitatissimum''). The oil is obtained by pressing, sometimes followed by solvent extraction. Owing to its polymer-forming properties, linseed oil is often blended with combinations of other oils, resins or solvents as an impregnator, drying oil finish or varnish in wood finishing, as a pigment binder in oil paints, as a plasticizer and hardener in putty, and in the manufacture of linoleum. Linseed oil use has declined over the past several decades with increased availability of synthetic alkyd resins—which function similarly but resist yellowing. Linseed oil is an edible oil in demand as a dietary supplement, as a source of α-Linolenic acid, an omega-3 fatty acid. In parts of Europe, it is traditionally eaten with potatoes and quark.
