How to develop oil paint by oneself?

How to develop oil paint by oneself? European classical masters made their own paints, which made the artist more familiar with the nature of the material he was using. Hand - made pigments have a charm that those produced by manufacturers often lack. Modern painters almost no one makes oil paints by themselves, because the oil paints sold on the market are rich and complete, relatively stable, and can basically meet the needs of painters. Although domestic oil painters are not satisfied with the performance of domestic colors, they will not make their own pigments, preferring to use all imported products, including canvases and tools. Although it is very troublesome to develop oil paints by oneself, it is very beneficial to understand the process of the development of pigments by classical European oil masters as oil painters. The basic components of oil paints are pigments and binders. The pigment powders used by the old masters came mostly from earth and minerals. The other part comes from plants or animals. The binder is made of resin, dry oil and grease, balsam and wax, but linseed oil is usually used directly. Common tools for grinding oil paints: a piece of thick glass or marble slab, a grinding mallet (pestle), a palette knife and a glass bottle or empty tin tube for storing paint. The pigment powder is poured on the glass plate. If it is a pigment block, it should be crushed into powder first, then slowly add linseed oil, and then grinding in circles, and mixing with a palette knife until the unique consistency of oil paint is obtained. The pigment powder must be carefully ground to eliminate the particles, so that the pigment powder and the linseed oil are fully and perfectly combined. Different pigment powder needs different amount of oil, the pigment powder can be ground into paste. Permeable pigments should not be ground too fine, otherwise the color. When grinding lead and other toxic pigments, prevent powder from entering the nose. The pigment developed with linseed oil can be coated only when the underlying pigment is completely dry, so it is absolutely impossible to paint with extremely thick painting method. It is most suitable for one-time painting method and monochrome painting method. To reverse this pure oil pigment, the linseed oil is mixed with 10% resin varnish and 2% wax dissolved in turpentine. Wax is added to increase the consistency of the paint (you do not need to add wax if you are using poppy oil). At the same time, it can not only reduce the yellow of linseed oil, but also prevent the separation of heavy pigments and oil. Partially ground pigments may harden after several days of storage and need to be further ground. About the pigment powder also can be made by themselves, life can see a beautiful color of soil or minerals can be trial produced
