Paint And Coatings Industry
Paint is any pigmented liquid, liquefiable, or solid mastic composition that, after application to a substrate in a thin layer, converts to a solid film. It is most commonly used to protect, color, or provide texture. Paint can be made in many colors—and in many different types. Paint is typically stored, sold, and applied as a liquid, but most types dry into a solid. Most paints are either oil-based or water-based and each has distinct characteristics. For one, it is illegal in most municipalities to discard oil-based paint down household drains or sewers. Clean-up solvents are also different for water-based paint than they are for 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.) Usually, the object being painted must be over , although some manufacturers of external paints/primers claim they can be applied when temperatures are as low as . History Paint was ...

Tempera
Tempera (), also known as egg tempera, is a permanent, fast-drying painting medium consisting of colored 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 Egg tempera was a primary method of painting until after 1500 when it was superseded by oil painting.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 combina ...

Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world. Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, ur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Litharge
Litharge (from Greek lithargyros, lithos (stone) + argyros (silver) ''λιθάργυρος'') is one of the natural mineral forms of lead(II) oxide, PbO. Litharge is a secondary mineral which forms from the oxidation of galena ores. It forms as coatings and encrustations with internal tetragonal crystal structure. It is dimorphous with the orthorhombic form massicot. It forms soft (Mohs hardness of 2), red, greasy-appearing crusts with a very high specific gravity of 9.14–9.35. PbO may be prepared by heating lead metal in air at approximately 600 °C (lead melts at only 300 °C). At this temperature it is also the end product of heating of other lead oxides in air. This is often done with a set of bellows pumping air over molten lead and causing the oxidized product to slip or fall off the top into a receptacle, where it quickly solidifies in minute scales. :PbO2 –(293 °C)→ Pb12O19 –(351 °C)→ Pb12O17 –(375 °C)→ Pb3O4 –(605 °C)→ PbO Historical term ...

Vasari
Giorgio Vasari (, also , ; 30 July 1511 – 27 June 1574) was an Italian Renaissance Master, who worked as a painter, architect, engineer, writer, and historian, who is best known for his work ''The Lives of the Most Excellent Painters, Sculptors, and Architects'', considered the ideological foundation of all art-historical writing, and the basis for biographies of several Renaissance artists, including Leonardo da Vinci and Michelangelo. Vasari designed the ''Tomb of Michelangelo'' in the Basilica of Santa Croce, Florence that was completed in 1578. Based on Vasari's text in print about Giotto's new manner of painting as a ''rinascita'' (rebirth), author Jules Michelet in his ''Histoire de France'' (1835) suggested adoption of Vasari's concept, using the term ''Renaissance'' (rebirth, in French) to distinguish the cultural change. The term was adopted thereafter in historiography and still is in use today. Life Vasari was born prematurely on 30 July 1511 in Arezzo, Tuscany. ...

Antonello Da Messina
Antonello da Messina, properly Antonello di Giovanni di Antonio, but also called Antonello degli Antoni and Anglicized as Anthony of Messina ( 1430February 1479), was an Italian painter from Messina, active during the Early Italian 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 disputed. 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 Netherlandish painting was ...

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. In a more narrow sense, 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-hydra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egg (food)
Humans and human ancestors have scavenged and eaten animal eggs for millions of years. Humans in Southeast Asia had domesticated chickens and harvested their eggs for food by 1,500 BCE. The most widely consumed eggs are those of fowl, especially chickens. Eggs of other birds, including ostriches and other ratites, 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. Bird and reptile eggs consist of a protective eggshell, albumen ( egg white), and vitellus ( egg yolk), contained within various thin membranes. Egg yolks and whole eggs store significant amounts of protein and choline, and are widely used in cookery. Due to their protein content, the United States Department of Agriculture formerly categorized eggs as ''Meats'' within the Food Guide Pyramid (now MyPlate). Despite the nutritional value of eggs, there are some potential health issues ... [...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. The oldest manuscript copies of the work 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. These aroused great interest as they 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. Theophilus' ''Schedula'' allows detailed insights into the techniques used in the applied arts in the high Middle Ages. The work is divided into three ...

Cennino Cennini
Cennino d'Andrea Cennini (c. 1360 – 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. Cennini was born in Colle di Val d'Elsa, 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. He is remembered mainly for having authored ''Il libro dell'arte''. Thought to have been written around the turn of the 15th century, the book is a "how to" on late Medieval and early Renaissance painting. It contains information on pigments, brushes, drawing, panel painting, the art of fresco, painting on fabrics and casting, amongst other techniques and tricks. Cennini also mentions oil painting in passing, which was important for dispelling the myth, propagated by Giorgio Vasari and Karel Van Mander, that oil painting was ...

Ardea (RM)
Ardea is an ancient town and ''comune ''in the Metropolitan City of Rome, south of Rome and about from today's Mediterranean coast. The economy is mostly based on agriculture, although, starting from the 1970s, industry has played an increasingly important role.
