How do oil paints come to be clear? What are the colors of all the pigments in oil painting?

There are many types of oils that can be diluted, it is better to use ready-made toning oil, and turpentine can also be used, but it is not recommended because the turpentine volatilizes quickly and the color will change after painting, it is best to use linseed oil (the most professional). Depending on the speed at which the pigment dries, you can configure the toning oil yourself. Prepare flaxseed oil, turpentine, walnut oil, olive oil and mix them in a certain proportion.

When you run out of oil brushes, you can clean them with soap and wrap them in newspaper at the end.

Turpentine, just go to the art supply store and buy a bottle, pour a little out in a small container when you use it, and cover it after use, it will volatilize and many people can't stand the pungent smell.

Finally, use turpentine to wash the pen, rinse it with water after removing most of the pigment, and finally wrap the bristles with newspaper. If you don't use it for a long time, you must wash the pen clean, because once the paint on the pen is dry, it will be wasted.

Oil painting dries slowly, and the more turpentine you have when you mix colors, the slower it dries.

It is also possible to use turpentine, but it boils quickly when painting with turpentine, which is not good, and the good side is that the paint painted on the painting dries quickly, which is conducive to emergency revision, and if you use "Da Vinci" toning oil, the painted painting will have to stay for a while before it can be modified.

After painting, you can use "banana water" to clean the brush. This "banana water" can clean the paintbrush very cleanly, but when using this "banana water", you should pay attention to safety, it is a flammable material.

First of all, the paint on the turpentine brush is almost cleaned, and then cleaned with warm boiled water and soap, when cleaning, it is necessary to pay attention to the position of the contact between the pen and the pen barrel to squeeze the remaining pigment and soap clean, and then clean it with soap, and finally wrap it with the tip of the washed pen in newspaper (so that it is easy to maintain the upright nature of the brush bristles, and it will be easier to use in the future).

Turpentine can, don't listen to other people's must not be cleaned with soap, not good for the pen, professional oil brushes, are pure, will be eroded!

Oil color is a special painting pigment for oil painting, which is made of pigment powder mixed with oil and ground by stirring and grinding. The basic components of oil paints, like other painting pigments, are composed of pigments, physique pigments, color carriers and certain auxiliary materials such as plasticizers, stabilizers, slow drying agents or driers. The pigment powder used by the ancient masters was more earthy and mineral.

1) Oils. According to the drying performance and drying time of the oil, oil (vegetable oil) is divided into dry oil, semi-dry oil, and non-dry oil.

Dry oil, easy to oxidize and dry in the air, forming flexibility.

Good solid membrane vegetable oil. For example, linseed oil.

Walnut oil, poppy oil.

Semi-dry oil, a vegetable oil that oxidizes in the air for a long time and has poor conjunctival ability. For example, soybean oil, sesame oil.

Non-drying oil, vegetable oil that cannot be oxidized and dried in the air to form a solid film. For example, castor oil.

Peanut oil, coconut oil.

2) The type of oil.

Polymeric oil - a liquid made by heating and polymerizing dry or semi-dry oil. The polymerized oil has a shiny and hard color after condensation.

Oxidizing oil – a liquid made by oxidizing polymeric oil.

Cooked oil - a liquid produced by heating or polymerizing dry or semi-dry oil, or catalyzing it with the addition of a catalyst.

Refined oil - liquid oil extracted from the oxidation of water and impurities in dry oil.

Thickened oil - a liquid oil formed after the oxidation of refined oil.

Dry vegetable oil or grease is the main film-forming substance and color-carrying agent of oil-based paints and oil paints, and there are two forms of oil, liquid oil and solid oil. According to the speed of oil drying and film formation, oil can be divided into dry oil, semi-dry oil and non-dry oil.

The natural drying time of dry oil is less than seven days, the conjunctiva is tough and water-resistant, has good elasticity, and cannot be dissolved after drying.

The drying time of semi-dry oil is more than seven days, the conjunctiva is soft and sticky, can be re-softened after drying, and is easily soluble in organic solvents.

Non-drying oils do not dry on their own under normal conditions and cannot be used in oil paints and mediators.

The basic requirements for oil painting oils used as color carriers and media agents are:

It can make the pigment disperse well in it, and the concentration and color of the outstanding material can be revealed.

It can bond the pigment together and adhere to the base, and the conjunctiva is tough and elastic.

It can adjust the consistency of the pigment to make it have a certain leveling or plasticity, and can adapt to various expression techniques.

It can be moistened for a certain period of time, so it is easy to continue painting.

The color is light, the transparency is good, and it does not affect the color of the pigment, especially the light-colored pigment.

An important oil used as a color carrier agent for oil paint and oil painting medium is a dry vegetable oil from plant seeds. Obviously, no single dry oil will meet the requirements in all five areas mentioned above. Flaxseed oil, poppy seed oil, walnut oil and safflower oil are more suitable for these requirements. Wait.

There are two solutions, one is that you just change the pigment. Your paint can be rotten for a long time, and it has dried out.

However, even if you change the pigment, diluting the pigment is still a very important skill that needs to be learned.

You said that after adding oil, it will become very slippery and greasy, and it can't dry, that's because the oil you use is too fat, too fat, too greasy, and heavy, and it is not suitable for diluting the pigment for the first and second layers of painting.

Oil painting pays attention to the principle of fat cover and thinness. Fat cover thin means that the oil of the color layer at the bottom layer should be hungry and thin, and the oil of the color layer at the upper level should be gradually fattened and thickened.

To make the bottom layer of oil thin, there are two points to pay attention to, one is to buy oil to buy lean (thin), you can choose the PLE cold-pressed flaxseed oil, do not choose fatty oil. Another point is that you can add turpentine or mineral essence and other things that can dilute the oil, mix it with the oil, and then use it to dilute the pigment.

Oil paints are paste-like and contain a lot of oil, which need to be diluted with turpentine and petroleum preparations when painting.

Oil paint is divided into three types: transparent, opaque and translucent, and can be applied in the picture with texture, color impastory, and transparent color, which is incomparable to other art pigments.

Oil paint is easy to accumulate and has a strong solidification type, which can well express the texture of the object, so that many factors such as vision, feeling and psychology can be comprehended accordingly.

The picture of impasto paint is rich in color, hang up the thicker color blocks with a spatula, and then add color layer by layer (but do not dilute the pigment with oil to avoid causing a greasy feeling to the picture).

Oil reflects the light, and the impasto paint causes the picture to be uneven, and the light is reflected in different directions, and the essence of the work can resonate with the author's thoughts.

Transparent or translucent oil paints were particularly prominent in the classicist and impressionist schools.
