Oil Paint
Oil paint is a type of slow-drying paint that consists of particles of pigment suspended in a drying oil, commonly linseed oil. The viscosity of the paint may be modified by the addition of a solvent such as turpentine or white spirit, and varnish may be added to increase the glossiness of the dried oil paint film. The addition of oil or alkyd medium can also be used to modify the viscosity and drying time of oil paint. Oil paints were first used in Asia as early as the 7th century AD and can be seen in examples of Buddhist paintings in Afghanistan. Oil-based paints made their way to Europe by the 12th century and were used for simple decoration, but oil painting did not begin to be adopted as an artistic medium there until the early 15th century. Common modern applications of oil paint are in finishing and protection of wood in buildings and exposed metal structures such as ships and bridges. Its hard-wearing properties and luminous colors make it desirable for both interi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bamiyan Valley
Bamyan or Bamyan Valley (); ( prs, بامیان) also spelled Bamiyan or Bamian is the capital of Bamyan Province in central Afghanistan. Its population of approximately 70,000 people makes it the largest city in Hazarajat. Bamyan is at an altitude of about above sea level. The Bamyan Airport is located in the middle of the city. The driving distance between Bamyan and Kabul in the southeast is approximately . The Band-e-Amir National Park is to the west, about a half-hour drive from the city of Bamyan. Bamyan is referred to by some as the "Shining Light" and "Valley of Gods".

Castor Oil
Castor oil is a vegetable oil pressed from castor beans. It is a colourless or pale yellow liquid with a distinct taste and odor. Its boiling point is and its density is 0.961 g/cm3. It includes a mixture of triglycerides in which about 90% of fatty acids are ricinoleates. Oleic acid and linoleic acid are the other significant components. Castor oil and its derivatives are used in the manufacturing of soaps, lubricants, hydraulic and brake fluids, paints, dyes, coatings, inks, cold-resistant plastics, waxes and polishes, nylon, and perfumes. Etymology The name probably comes from a confusion between the '' Ricinus'' plant that produces it and another plant, the '' Vitex agnus-castus''. An alternative etymology, though, suggests that it was used as a replacement for castoreum. Composition Castor oil is well known as a source of ricinoleic acid, a monounsaturated, 18-carbon fatty acid. Among fatty acids, ricinoleic acid is unusual in that it has a hydroxyl functiona ...

Pine Nut Oil
Pine nut oil, also called ''pine seed oil'' or ''cedar nut oil'', is a vegetable oil, extracted from the edible seeds of several species of pine. While the oil produced from the seeds of more common European and American pine varieties is mostly used for culinary purposes, Siberian pines (growing in Russia, Mongolia and Kazakhstan), as well as Korean pines (growing mostly in China and North Korea) yield the seeds with the highest content of pinolenic acid, as well as antioxidants associated with medicinal uses. Culinary uses Pine nut oil has a relatively low smoke point, and is therefore not generally used during cooking. Rather, it is added to foods for "finishing", to add flavor. Pine nut oil is also a useful bread preservative when a small amount is added to the dough. Triglyceride composition One analysis of the triglyceride composition of Siberian pine nut oil showed the following composition: See also * Phytonutrients * Phytochemicals Phytochemicals are chem ...

Hemp Oil
Hemp oil (hemp seed oil) is oil obtained by pressing hemp seeds. Cold pressed, unrefined hemp oil is dark to clear light green in color, with a nutty flavor. The darker the color, the grassier the flavour. It should not be confused with hash oil, a tetrahydrocannabinol-containing oil made from the ''Cannabis'' flower. Description Refined hemp seed oil is clear and colorless, with little flavor. It is primarily used in body care products. Industrial hemp seed oil is used in lubricants, paints, inks, fuel, and plastics. Hemp seed oil is used in the production of soaps, shampoos and detergents. The oil has a 3:1 ratio of omega-6 to omega-3 essential fatty acids. It may also be used as a feedstock for the large-scale production of biodiesel. Manufacture Hemp seed oil is manufactured from varieties of ''Cannabis sativa'' that do not contain significant amounts of tetrahydrocannabinol (THC), the principal psychoactive element present in the cannabis plant. This manufacturing pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poppyseed Oil
Poppyseed oil (also poppy seed oil and poppy oil) is an edible oil obtained from poppy seeds (specifically seeds of ''Papaver somniferum'', the opium poppy). Poppy seeds yield 45–50% oil. Like poppy seeds, poppyseed oil is highly palatable, high in vitamin E, and has no narcotic properties. Poppy seeds are especially high in tocopherols other than vitamin E (alpha-tocopherol). Compared to other vegetable oils, poppyseed oil has a moderate amount of phytosterols: higher than soybean oil and peanut oil, lower than safflower oil, sesame oil, wheat germ oil, corn oil, and rice bran oil. It has little or no odor and a pleasant taste, and it is less likely than some other oils to become rancid. Uses The oil is sometimes used as a cooking oil; it is also used for moisturizing skin. Its primary use, however, is in the manufacture of paints, varnishes, and soaps. Poppyseed oil is a drying oil. In oil painting, the most popular oil for binding pigment, thinning paint, and varn ...

Walnut Oil
Walnut oil is oil extracted from walnuts, '' Juglans regia''. The oil contains polyunsaturated fatty acids, monounsaturated fatty acids, and saturated fats. Composition Walnut oil is composed largely of polyunsaturated fatty acids (72% of total fats), particularly alpha-linolenic acid (14%) and linoleic acid (58%), oleic acid (13%), and saturated fats (9%). Culinary use Walnut oil is edible and is generally used less than other oils in food preparation, often due to high pricing. It is light-coloured and delicate in flavour and scent, with a nutty quality. Although chefs sometimes use walnut oil for pan-frying, most avoid walnut oil for high-temperature cooking because heating tends to reduce the oil's flavour and produce a slight bitterness. Walnut oil is preferred in cold dishes such as salad dressings. Cold-pressed walnut oil is typically more expensive due to the loss of a higher percentage of the oil. Refined walnut oil is expeller-pressed and saturated with solvent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Encaustic Painting
Encaustic painting, also known as hot wax painting, is a form of painting that involves a heated wax medium to which colored pigments have been added. The molten mix is applied to a surface—usually prepared wood, though canvas and other materials are sometimes used. The simplest encaustic medium could be made by adding pigments to wax, though recipes most commonly consist of beeswax and damar resin, potentially with other ingredients. For pigmentation, dried powdered pigments can be used, though some artists use pigmented wax, inks, oil paints or other forms of pigmentation. Metal tools and special brushes can be used to shape the medium as it cools. Also, heated metal tools, including spatulas, knives and scrapers, can be used to manipulate the medium after it has cooled onto the surface. Additionally, heat lamps, torches, heat guns, and other methods of applying heat are used by encaustic artists to fuse and bind the medium. Because encaustic medium is thermally malleab ...

Mastic (plant Resin)
Mastic ( el, Μαστίχα) is a resin obtained from the mastic tree (''Pistacia lentiscus''). It is also known as tears of Chios, being traditionally produced on the island Chios, and, like other natural resins, is produced in "tears" or droplets. Mastic is excreted by the resin glands of certain trees and dries into pieces of brittle, translucent resin. When chewed, the resin softens and becomes a bright white and opaque gum. The flavor is bitter at first, but after some chewing, it releases a refreshing flavor similar to pine and cedar. History Mastic has been harvested for at least 2,500 years since Greek antiquity. The word ''mastic'' is derived from grc-gre, μαστιχάειν, masticháein, 'to gnash the teeth', which is also the source of the English word ''masticate''. The first mention of actual mastic 'tears' was by Hippocrates. Hippocrates used mastic for the prevention of digestive problems, colds and as a breath freshener. Romans used mastic along with honey, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vegetable Fats And Oils
Vegetable oils, or vegetable fats, are oils extracted from seeds or from other parts of fruits. Like animal fats, vegetable fats are ''mixtures'' of triglycerides. Soybean oil, grape seed oil, and cocoa butter are examples of seed oils, or fats from seeds. Olive oil, palm oil, and rice bran oil are examples of fats from other parts of fruits. In common usage, vegetable ''oil'' may refer exclusively to vegetable fats which are liquid at room temperature. Vegetable oils are usually edible. Uses In antiquity Oils extracted from plants have been used since ancient times and in many cultures. Archaeological evidence shows that olives were turned into olive oil by 6000 BCE and 4500 BCE in present-day Israel and Palestine. In addition to use as food, fats and oils (both vegetable and mineral) have long been used as fuel, typically in lamps which were a principal source of illumination in ancient times. Oils may have been used for lubrication, but there is no evidence for this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
