Oil painting as a system of the complete picture, first fell not after emerging in the service of the feudal system of aristocratic family life, social life and political life, give priority to with portrait or episodic portrait. Great Raphael is known for idealized frame portraits. The period also produced outstanding court painter WeChat: LSZ - YS old town of deep oil painting art, such as lotus, bein. Then the subject matter of this type in gradually to mythology, religion, war, ShiSu amorous feelings, the real modal is given priority to, then to level, vocabulary, structure symbol as the focus, formed the most colorful map of human civilization of a kingdom. Oil painting's long-term prosperity depends on its material basis - oil painting materials. And this must be from the whole painting material base to talk about.
(a) classification of painting materials is introduced
1, the glue
Oxidation of solidification, under the general temperature can't become a fluid called irreversible adhesive. Used in the oil painting base adhesive must be cured rubber irreversible. Base is unfavorable and thick coating, it is advisable to add water 4-5 times. Irreversible adhesive glue on the purpose of the painting, the other is a water-soluble pigment binder; Painting as a polish on the surface of the material. Irreversible plastic plant gum, gelatin, casein glue, its plain and white latex.
Vegetable gum
It is mainly used for making agent. Should not be boiled, with 25 times more water brew. Gum Arabic and tragacanth need to add a little alcohol after stirring, then adding water.
Animal glue
Hide glue, bone glue, isinglass, antler glue, etc. Heating and 60 ℃ cold water soak a day and night, stirring, adhesive and water ratio of 1:10.
Casein adhesive
Namely casein adhesive, the 20th century began to used in paint, chemical stores.
Methyl cellulose gum
Can be used as a white glue, chemical store offers the packet.
White latex
Composition is polyvinyl formal. From the hardware store to buy water of white latex, rubber ratio is 1:4, can be directly to the substrate.
Reversible glue can also play a role in painting: alum can anticorrosive, each kilogram of adhesive solution can add 10 grams of alum with anti-corrosion (few drops carbolic acid, Yang acid, borax and 6:125 water also can substitute); Glycerine and honey can be used as a reinforcement and crack. )

2, oil
Drying oil will meet oxygen oxidation coagulation agent oil must be drying oil, important drying oil with linseed oil and walnut oil. But heaven fire of linseed oil, walnut oil is not attached drawing requirements of cooperation, because they have been oxidized to solid. But raw linseed oil, walnut oil oxidation so slowly again, not the cementation ability. So meet the requirements is only half cooked. Half-cooked linseed oil is the main element of the color mixing of oil. How to make out half-cooked linseed oil? Method is the linseed oil is filled into the jar, glass bottles, mouth block on the gauze, placed in ventilated place insolate one month, the oil will become transparent and pure, thick of oil. Oily thicken because of oxidation. To cook the raw walnut oil into half way up. Others use the method of low temperature heating handling raw walnut oil (see the second part of Iraq will section). Be drying oil, peanut oil, soybean oil and so on not curing, not accord with the requirement of drawing WeChat: LSZ - YS old town of deep oil painting art.
Turpentine is the most commonly used paint diluted media agent, composed of rosin distillation, medicinal to pure in industrial use. Pure gasoline can instead of turpentine oil, but the problem is that it is always more impurities, volatile too fast. So the most can be used to wash the pen.
Key material is resin oil, light oil content of resin is not famous oil painting pure will make the dark. Preparation of light oil can be a drying oil, oil can be volatile oil. But not gasoline, it too many impurities. Usually use turpentine. Light oil, turpentine oil ratio is 2:1, with resin and should cooperate with these two things as agent, proportion should be 3:1, the darma fat and fat is superior of the two kinds of resin with light oil, the former is more expensive, domestic production, which can also be used "frankincense" instead of traditional Chinese medicine store.
Half light oil and wax or silica (Sio2). Beeswax no more than a quarter.
Quick-drying oil
Method is to put the linseed oil or walnut oil into a shallow pan, cover glass, insolate transplanting.
Slow drying oil
Clove oil drip into the color, can make the dry slow, drip clove oil color mixing of oil that is to say, is the slow drying oil.
Heavy oil painting light
Natural resin and clove oil is in composition, and if not in case of an emergency where shouldn't interrupt interrupted, general use less than it.
Most complete the most practical oil painting reproductions knowledge and techniques, collection no regret!
3, paint
Under the movement of the pen, if mutual adhesion of pigment particles into larger particles, it picture transparency reduced (larger particles pigment reflect light chaos, can make the picture hair black, dim). Claborate-style painting mask before dyeing with mine looking for rendering, because this kind of pigment particles is not easy to turn on the cover color.
Good painting for the color in the first times (it will take about 10 hours) and the second time after painting, is to prevent oil absorption. There is no "glaze" YanLiaoCeng would, without burnish.
4, resin
Resin (resin) resin, Marty thoroughly oxidation after solidification, the surface of the painting is a layer of shiny solid enamel knot. It is the source of a medium of drying oil, one is dissolved ready-made resin (use turpentine) of light oil. In terms of stability, which is good. Light oil painting on the resin is in fact the proportion is less than the room with a mixture of turpentine oil resin.
Resin glue sex, can alleviate the lower level of ground. The first to give full play to the role of resin greatly liberated the calligraphy masters are goya.
5, other
chalk
One of the most ancient painting materials. Many primitive caves mural is drawn with chalk, charcoal, clay.
white
Titanium white is easy to return; Lead white fear of oil; Zinc long will become yellow. Lead white oil, because mild chemical reaction happens. Lead white opera is very suitable for Dan.
Lithopone lithopone, composition of zinc sulfide and barium sulfide. Brush base with is much more absorbent base; With less is the neutral base; Lithopone all need not, only use glue or oily base, that is not absorbent base. The least oil absorption, is made of oil base oil base, can make the picture appear very good sense of stratification.
Wood tenon live
Within the frame set both inside and outside the frame makes the best two live, so that with the temperature change and correspondingly adjust tightness.
