Paintwork
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. Primitive forms of paint were used tens of thousands of years ago in cave paintings. Clean-up solvents are also different for water-based paint than oil-based paint. Water-based paints and oil-based paints will cure differently based on the outside ambient temperature of the object being painted (such as a house). History Paint was used in some of the earliest known human artworks. Some cave paintings drawn with red or yellow ochre, hematite, manganese oxide, and charcoal may have been made by early ''Homo sapiens'' as long as 40,000 years ago. Paint may be even older. In 2003 and 2004, South African archeologists reported finds in Blombos Cave of a 100,000-yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poster Paint
Poster paint (also known as ''tempera paint'' in the US, ''poster color'' in Asia) is a Distemper (paint), distemper paint that usually uses starch, cornstarch, cellulose, gum-water or another glue Sizing, 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. Asian poster paints are similar to gouache, albeit has a thinner viscosity, uses gum arabic and/or dextrin as a binder, and use inexpensive and less lightfast pigments more coarsely ground, with added brighteners to make the paints affordable. Poster colors are used in art classes, in animation production, and in scanning and printing. Notable brands that produce poster colors include Kokuyo Camlin, Monami, Pentel, Sakura Color Products Corporation, Sakura, anNicker See also * Gouache * Tempera, the common name for Poster paint in the US and also a fine art painting material using egg yolk as a binder References * Ralph Mayer, ''The ...

Vasari
Giorgio Vasari (30 July 1511 – 27 June 1574) was an Italian Renaissance painter, architect, art historian, and biographer who is best known for his work '' Lives of the Most Excellent Painters, Sculptors, and Architects'', considered the ideological foundation of Western art-historical writing, and still much cited in modern biographies of the many Italian Renaissance artists he covers, including Leonardo da Vinci and Michelangelo, although he is now regarded as including many factual errors, especially when covering artists from before he was born. Vasari was a Mannerist painter who was highly regarded both as a painter and architect in his day but rather less so in later centuries. He was effectively what would now be called the minister of culture to the Medici court in Florence, and the ''Lives'' promoted, with enduring success, the idea of Florentine superiority in the visual arts. Vasari designed the ''Tomb of Michelangelo'', his hero, in the Basilica of Santa Cro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antonello Da Messina
Antonello da Messina (; 1425–1430February 1479), properly Antonello di Giovanni di Antonio, but also called Antonello degli Antoni and Anglicized as Anthony of Messina, was an Italian painter from Messina, active during the Italian Early Renaissance. His work shows strong influences from Early Netherlandish painting, although there is no documentary evidence that he ever travelled beyond Italy. Giorgio Vasari credited him with the introduction of oil painting into Italy, although this is now regarded as wrong. Unusually for a southern Italian artist of the Renaissance, his work proved influential on painters in northern Italy, especially in Venice. Biography Early life and training Antonello was born at Messina around 1429–1431, to Garita (Margherita) and Giovanni de Antonio Mazonus, a sculptor who trained him early on. He and his family resided in the Sicofanti district of the city. Antonello is thought to have apprenticed in Rome before going to Naples, where Netherla ...

Diluent
A diluent (also referred to as a filler, dilutant or thinner) is a diluting agent. Certain fluids are too viscous to be pumped easily or too dense to flow from one particular point to the other. This can be troublesome, because it might not be economically feasible to transport such fluids in this state. To ease this restricted movement, diluents are added. This decreases the viscosity of the fluids, thereby also decreasing the pumping/transportation costs. One industrial application is the transport of crude oil via pipelines. Heavy crude oil/bitumen are fluids with high viscosity, especially at low temperatures. The addition of a diluent enables the diluted fluid ( dilbit in the case of bitumen) to meet pipeline specifications in order for it to be efficiently transported. Typical diluent in this case is naphtha or condensate. Types of diluents more familiar to the general public include paint thinner and nail polish thinner, both of which improve the consistency and app ...

Binder (material)
A binder or binding agent is any material or substance that holds or draws other materials together to form a cohesive whole mechanically, chemically, by adhesion or cohesion. More narrowly, binders are liquid or dough-like substances that harden by a chemical or physical process and bind fibres, filler powder and other particles added into it. Examples include glue, adhesive and thickening. Examples of mechanical binders are bond stones in masonry and tie beams in timber framing. Classification Binders are loosely classified as organic ( bitums, animal and plant glues, polymers) and inorganic ( lime, cement, gypsum, liquid glass, etc.). These can be either metallic or ceramic as well as polymeric depending on the nature of the main material. For example, in the compound WC-Co (Tungsten Carbide used in cutting tools) Co constitutes the binding agent for the WC particles. Based on their chemical resistance, binders are classified by the field of use: non-hydrau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egg (food)
Humans and other hominids have consumed eggs for millions of years. The most widely consumed eggs are those of fowl, especially chickens. People in Southeast Asia began harvesting chicken eggs for food by 1500 BCE. Eggs of other birds, such as ducks and ostriches, are eaten regularly but much less commonly than those of chickens. People may also eat the eggs of reptiles, amphibians, and fish. Fish eggs consumed as food are known as roe or caviar. Hens and other egg-laying creatures are raised throughout the world, and mass production of chicken eggs is a global industry. In 2009, an estimated 62.1 million metric tons of eggs were produced worldwide from a total laying flock of approximately 6.4 billion hens. There are issues of regional variation in demand and expectation, as well as current debates concerning methods of mass production. In 2012, the European Union banned battery husbandry of chickens. History Bird eggs have been valuable foodstuffs since prehistory, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theophilus Presbyter
Theophilus Presbyter (fl. c. 1070–1125) is the pseudonymous author or compiler of a Latin text containing detailed descriptions of various medieval arts, a text commonly known as the ''Schedula diversarum artium'' ("List of various arts") or ''De diversis artibus'' ("On various arts"), probably first compiled between 1100 and 1120. Work The oldest manuscript copies of ''De diversis artibus'' are found in Vienna (Austrian National Library, Codex 2527) and in Wolfenbüttel (Herzog-August-Bibliothek, Cod. Guelf. Gud. Lat. 69 2°). Gotthold Ephraim Lessing rediscovered the document when he worked as librarian in Wolfenbüttel, and published excerpts in 1774. The work contains perhaps the earliest reference to oil paint, which aroused great interest as the mention disproved Vasari's myth of Jan van Eyck developing the technique of oil painting in the early 15th century, about which antiquaries had already become suspicious. It also contains what seems to be the earliest textual evi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egg Tempera
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. Etymology The term ''tempera'' is derived from the Italian ''dipingere a tempera'' ("paint in distemper"), from the Late Latin ''distemperare'' ("mix thoroughly"). History Tempera painting has been found on early Egyptian sarcophagus decorations. Many of the Fayum mummy portraits use tempera, sometimes in comb ...

Cennino Cennini
Cennino d'Andrea Cennini (; – before 1427) was an Italian painter influenced by Giotto. He was a student of Agnolo Gaddi in Florence. Gaddi trained under his father, called Taddeo Gaddi, who trained with Giotto. He is remembered mainly for having authored ''Il libro dell'arte''. Cennini was born in Colle di Val d'Elsa, present-day Tuscany. After training as an artist with Agnolo Gaddi in Florence he worked at the court of Francesco Novello da Carrara in Padua for some years before apparently returning to Colle di Val d'Elsa. His book ''Il libro dell'arte'' is a "how to" on late Medieval and early Renaissance painting, and thought to have been written around the turn of the 15th century. It contains information on pigments, brushes, drawing, panel painting, the art of fresco, painting on fabrics and casting, amongst other techniques and tricks. Theophilus (Roger of Helmerhausen), in his treatise ''On Divers Arts'' (1125), mentions oil painting, and so does Cennini, in p ...
