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 ...

Polymer
A polymer () is a chemical substance, substance or material that consists of very large molecules, or macromolecules, that are constituted by many repeat unit, repeating subunits derived from one or more species of monomers. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compound (chemistry), compounds, produces unique physical property, physical properties including toughness, high rubber elasticity, elasticity, viscoelasticity, and a tendency to form Amorphous solid, amorphous and crystallization of polymers, semicrystalline structures rath ...

Watercolors
Watercolor (American English) or watercolour (Commonwealth English; see spelling differences), also ''aquarelle'' (; from Italian diminutive of Latin 'water'), is a painting method"Watercolor may be as old as art itself, going back to the Stone Age when early ancestors combined earth and charcoal with water to create the first wet-on-dry picture on a cave wall." in which the paints are made of pigments suspended in a water-based solution. ''Watercolor'' refers to both the medium and the resulting artwork. Aquarelles painted with water-soluble colored ink instead of modern water colors are called (Latin for "aquarelle made with ink") by experts. However, this term has now tended to pass out of use. The conventional and most common support—material to which the paint is applied—for watercolor paintings is watercolor paper. Other supports or substrates include stone, ivory, silk, reed, papyrus, bark papers, plastics, vellum, leather, fabric, wood, and watercolor canvas (c ...

Rubbing Alcohol
Rubbing alcohol, known as surgical spirit in the British Pharmacopoeia, refers to a group of denatured alcohol solutions commonly used as topical disinfectant. In addition to its medical applications, rubbing alcohol is employed in various industrial and household contexts. These solutions are primarily composed of either isopropyl alcohol (isopropanol) or ethanol, with isopropyl alcohol being the more widely available formulation. The United States Pharmacopeia (USP) defines "isopropyl rubbing alcohol USP" as a solution containing approximately 70% alcohol by volume of pure isopropanol, while "rubbing alcohol USP" refers to a solution containing approximately 70% by volume of denatured ethanol. In Ireland and the United Kingdom, the comparable product is "surgical spirit B.P.", defined by the British Pharmacopoeia as containing 95% methylated spirit, 2.5% castor oil, 2% diethyl phthalate, and 0.5% methyl salicylate. Known alternatively as "wintergreen oil", methyl salicylate is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Translucent
In the field of optics, transparency (also called pellucidity or diaphaneity) is the physical property of allowing light to pass through the material without appreciable light scattering by particles, scattering of light. On a macroscopic scale (one in which the dimensions are much larger than the wavelengths of the photons in question), the photons can be said to follow Snell's law. Translucency (also called translucence or translucidity) is the physical property of allowing light to pass through the material (with or without scattering of light). It allows light to pass through but the light does not necessarily follow Snell's law on the macroscopic scale; the photons may be scattered at either of the two interfaces, or internally, where there is a change in the index of refraction. In other words, a translucent material is made up of components with different indices of refraction. A transparent material is made up of components with a uniform index of refraction. Transparent m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opacity (optics)
Opacity is the measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light. In radiative transfer, it describes the absorption and scattering of radiation in a medium, such as a plasma, dielectric, shielding material, glass, etc. An opaque object is neither transparent (allowing all light to pass through) nor translucent (allowing some light to pass through). When light strikes an interface between two substances, in general, some may be reflected, some absorbed, some scattered, and the rest transmitted (also see refraction). Reflection can be diffuse, for example light reflecting off a white wall, or specular, for example light reflecting off a mirror. An opaque substance transmits no light, and therefore reflects, scatters, or absorbs all of it. Other categories of visual appearance, related to the perception of regular or diffuse reflection and transmission of light, have been organized under the concept of cesia in an order sys ...

Consistency - Thickness, Viscosity
Viscosity is a measure of a fluid's rate-dependent resistance to a change in shape or to movement of its neighboring portions relative to one another. For liquids, it corresponds to the informal concept of ''thickness''; for example, syrup has a higher viscosity than water. Viscosity is defined scientifically as a force multiplied by a time divided by an area. Thus its SI units are newton-seconds per metre squared, or pascal-seconds. Viscosity quantifies the internal frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced through a tube, it flows more quickly near the tube's center line than near its walls. Experiments show that some stress (such as a pressure difference between the two ends of the tube) is needed to sustain the flow. This is because a force is required to overcome the friction between the layers of the fluid which are in relative motion. For a tube with a constant rate of flow, the streng ...

Palette (painting)
A palette () is a surface on which a painter arranges and mixes paints. A palette is made of materials such as wood, paper, glass, ceramic or plastic, and can vary greatly in size and shape. Watercolor palettes are generally made of plastic or porcelain in a rectangular or wheel format, and have built in wells and mixing areas for colors. For acrylic painting, "stay wet" palettes exist, which prevent the paints from drying out and becoming inert. A classical palette is most often oval, but can also be rectangular, and is tapered to ensure optimal distribution of weight. It has a thumbhole and insert for brushes, and is designed to be held in the non-dominant hand while the other is used to mix and paint. However, some well-known artists have used more unconventional palettes; for instance, Picasso used a sheet of newspaper. Palettes are also a universal symbol of painting and art in general, alongside paintbrushes, for example in the symbol of Microsoft Paint. See also * Palet ...

Acrylic Paints
Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion and plasticizers, silicone oils, defoamers, stabilizers, or metal soaps. Most acrylic paints are water-based, but become water-resistant when dry. Depending on how much the paint is diluted with water, or modified with acrylic gels, mediums, or pastes, the finished acrylic painting can resemble a watercolor, a gouache, or an oil painting, or it may have its own unique characteristics not attainable with other media. Water-based acrylic paints are used as latex house paints, as latex is the technical term for a suspension of polymer microparticles in water. Interior latex house paints tend to be a combination of binder (sometimes acrylic, vinyl, PVA, and others), filler, pigment, and water. Exterior latex house paints may also be a co-polymer blend, but the best exterior water-based paints are 100% acrylic, because of its elasticity and other factors. Vinyl, however, costs half of wha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acrylic Retarder
In painting, a retarder is a substance, usually a glycol and usually added to water, that is used to slow the drying time of acrylic paints, giving more time for blending or layering highlights. Use in fine art Retarders are used to counter the fast drying properties of acrylic paints, making possible the usage of wet-on-wet or other techniques which would otherwise require oil paints. When used correctly, they can keep the paint wet from half an hour extra to a full day's working time. Applying too much retardant, however, can prevent a layer from drying correctly for as long as the retardant is present, causing future damage to the painting unless the affected layer of paint is removed or re-mixed. Content They generally contain glycol (such as propylene glycol), or glycerin-based additives. Home-Made For home-made acrylic retarder, water glycerol Glycerol () is a simple triol compound. It is a colorless, odorless, sweet-tasting, viscous liquid. The glycerol backbone is f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
