Scumbling
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 pa ...

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 (Any color that is absent of white, grey, or black)"., 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 (color), Hunt effect). * Chroma is the "colorfulness of an area judged as a proportion of the brightness of a similarl ...

Faux Finishing
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 wh ...

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
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 wash * Venetian plaster Reference ...

Epoxy Glazing
Ceramic fixtures are being more commonly glazed with 2 part epoxy compounds. The first component is a clear or Opacity (optics), 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_(plastic), Formica countertops can also be glazed in this fashion using a faux stone or granite look. References {{reflist Ceramic glazes ...

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. Since acrylic paint dries at a faster rate than other types of paint, some techniques require more swift execution before the paint dries. There are benefits to adding water before it dries out completely, because the paint can be manipulated for longer before drying. Acrylic paint eliminates the need for turpentine and gesso, and can be applied directly onto the canvas, though gesso can still be used to improve the look of a painting and provide a smoother surface to work with. Artists use various paint brushes and a multi color palette to help them find and refine painting techniques. 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 ...

Glycerin
Glycerol () is a simple triol compound. It is a colorless, odorless, sweet-tasting, viscous liquid. The glycerol backbone is found in lipids known as glycerides. 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 Hygroscopy, hygroscopic in nature. Modern use of the word glycerine (alternatively spelled glycerin) refers to commercial preparations of less than 100% purity, typically 95% glycerol. Structure Although chirality, achiral, glycerol is prochirality, prochiral with respect to reactions of one of the two primary alcohols. Thus, in substituted derivatives, the Glycerophospholipid#Nomenclature and stereochemistry, stereospecific numbering labels the molecule with a ''sn''- prefix before the stem name of the molecule. Production Natural sources Glycerol is generally obtained from plant and animal sources where it occurs in triglycerides, est ...

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 distinction is meaningful 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, 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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linseed Oil
Linseed oil, also known as flaxseed oil or flax oil (in its edible form), is a colorless 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.

Kerosene
Kerosene, or paraffin, is a combustibility, combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in Aviation fuel, aviation as well as households. Its name derives from the Greek (''kērós'') meaning "wax"; it was registered as a trademark by Nova Scotian, Nova Scotia geologist and inventor Abraham Pineo Gesner, Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. Kerosene is widely used to power jet engines of aircraft (jet fuel), as well as some rocket engines in a highly refined form called RP-1. It is also commonly used as a cooking and lighting fuel, and for fire toys such as Poi (performance art)#Fire poi, poi. In parts of Asia, kerosene is sometimes used as fuel for small outboard motors or even motorcycles. World total kerosene consumption for all purposes is equivalent to about 5,500,000 barrels per day as of July 2023. The term "kerosene" is comm ...
