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.
Oil painting is a painting method involving the procedure of painting with pigments with a medium of drying oil as the binder. It has been the most common technique for artistic painting on canvas, wood panel or copper for several centuries, spreading from Europe to the rest of the world. The advantages of oil for painting images include "greater flexibility, richer and denser colour, the use of layers, and a wider range from light to dark". But the process is slower, especially when one layer of paint needs to be allowed to dry before another is applied.
Paint is a material or mixture that, when applied to a solid material and allowed to dry, adds a film-like layer. As art, this is used to create an image or images known as a painting. Paint can be made in many colors and types. Most paints are either oil-based or water-based, and each has distinct characteristics.
A pastel is an art medium that consist of powdered pigment and a binder. It can exist in a variety of forms, including a stick, a square, a pebble, or a pan of color, though other forms are possible. The pigments used in pastels are similar to those used to produce some other colored visual arts media, such as oil paints; the binder is of a neutral hue and low saturation. The color effect of pastels is closer to the natural dry pigments than that of any other process.
Tempera, also known as egg tempera, is a permanent, fast-drying painting medium consisting of pigments mixed with a water-soluble binder medium, usually glutinous material such as egg yolk. Tempera also refers to the paintings done in this medium. Tempera paintings are very long-lasting, and examples from the first century AD still exist. Egg tempera was a primary method of painting until after 1500 when it was superseded by oil painting. A paint consisting of pigment and binder commonly used in the United States as poster paint is also often referred to as "tempera paint", although the binders in this paint are different from traditional tempera paint.
Watercolor or watercolour, also aquarelle, is a painting method 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 aquarellum atramento by experts. However, this term has now tended to pass out of use.
Gum arabic is a natural gum originally consisting of the hardened sap of two species of the Acacia tree, Senegalia senegal and Vachellia seyal. However, the term "gum arabic" does not actually indicate a particular botanical source. The gum is harvested commercially from wild trees, mostly in Sudan and throughout the Sahel, from Senegal to Somalia. The name "gum Arabic" was used in the Middle East at least as early as the 9th century. Gum arabic first found its way to Europe via Arabic ports, and so retained its proper name.
In art, watermedia is the general term for media that are distinguished from oil or other media by being diluted with water when used. Watermedia include watercolors, gouache and acrylic, amongst others. It is sometimes combined with other media, commonly collage.
Water-miscible oil paint is oil paint either engineered or to which an emulsifier has been added, allowing it to be thinned and cleaned up with water. These paints make it possible to avoid using, or at least reduce volatile organic compounds such as turpentine that may be harmful if inhaled. Water-miscible oil paint can be mixed and applied using the same techniques as traditional oil-based paint, but while still wet it can be removed from brushes, palettes, and rags with ordinary soap and water. One of the ways its water solubility comes from is the use of an oil medium in which one end of the molecule has been engineered to be hydrophilic and thus bind loosely to water molecules, as in a solution. This type of paint is different to those that are engineered to enable cleaning of brushes and application equipment in water but are not in themselves water reducible.
Casein paint, derived from milk casein, is a fast-drying, water-soluble medium used by artists.
Poster paint is a distemper paint that usually uses starch, cornstarch, cellulose, gum-water or another glue size as its binder. It either comes in large bottles or jars or in a powdered form. It is normally a cheap paint used in school art classes.
Sennelier is a French manufacturing company of art materials, mostly famous for its hand selected pigments. The company produces a wide range of paint products, including acrylic, oil, watercolor, gouache, oil and soft pastel, india ink, tempera, and other media.
Drybrush is a painting technique in which a paint brush that is relatively dry, but still holds paint, is used to create a drawing or painting. Load is applied to a dry support such as paper or primed canvas. The resulting brush-strokes have a characteristic scratchy and textured look that lacks the smooth appearance that washes or blended paint commonly have. This technique can be used to achieve a blurred or soft appearance.
A wash is a term for a visual arts technique resulting in a semi-transparent layer of colour. A wash of diluted ink or watercolor paint applied in combination with drawing is called pen and wash, wash drawing, or ink and wash. Normally only one or two colours of wash are used; if more colours are used the result is likely to be classified as a full watercolor painting.
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 and are soluble in water. Since this type of paint dries quickly you will need to work somewhat quickly if you do not want your paint to dry out. There are benefits to adding water before it dries out completely because you can reactivate the paint. These types of paint eliminate the need for turpentine and gesso, and can be applied directly onto canvas. Although they do not need gesso it can be beneficial to give your canvas a few coats of gesso to improve the life of the painting and have a smoother surface to work with. Having various paint brushes and a multi color palette is helpful in finding a technique that works for you. Aside from painting with concentrated color paints, acrylics can also be watered down to a consistency that can be poured or used for glazes.
Painting is a visual art, which is characterized by the practice of applying paint, pigment, color or other medium to a solid surface. The medium is commonly applied to the base with a brush, but other implements, such as knives, sponges, and airbrushes, may be used. One who produces paintings is called a painter.
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.
Watercolor paper is paper or substrate onto which an artist applies watercolor paints, pigments, or dyes. Many types of watercolour papers that are manufactured for the use of watercolors are currently available. Watercolor paper can be made of wood pulp exclusively, or mixed with cotton fibers. Pure cotton watercolor paper is also used by artists, though it typically costs more than pulp-based paper. It is also available as an acid-free medium to help its preservation.
The conservation and restoration of paintings is carried out by professional painting conservators. Paintings cover a wide range of various mediums, materials, and their supports. Painting types include fine art to decorative and functional objects spanning from acrylics, frescoes, and oil paint on various surfaces, egg tempera on panels and canvas, lacquer painting, water color and more. Knowing the materials of any given painting and its support allows for the proper restoration and conservation practices. All components of a painting will react to its environment differently, and impact the artwork as a whole. These material components along with collections care will determine the longevity of a painting. The first steps to conservation and restoration is preventive conservation followed by active restoration with the artist's intent in mind.
Paint mixing is the practice of mixing components or colors of paint to combine them into a working material and achieve a desired hue. The components that go into paint mixing depend on the function of the product sought to be produced. For example, a painter of portraits or scenery on a canvas may be seeking delicate hues and subtle gradiations, while the painter of a house may be more concerned with durability and consistency of colors in paints presented to customers, and the painter of a bridge or a ship may have the weatherability of the paint as their primary concern.
