turpentine can be used to dilute pigments.
To a certain extent, reduce the oiliness of oil painting pigment itself, and it can be completely volatilized in a minute or two, and it is dull after drying.
The oil painting made by blending turpentine and pigments is oil-free and matte after drying. To achieve a matte effect, turpentine can be used to draw the whole process.
turpentine can easily clean the paint-covered brush, and the paint attached to the picture has strong hardness, which can keep luster for a long time after the picture is dried.
linseed oil, walnut oil and poppy oil are generally diluted by turpentine. In oil painting, it is said that the content of linseed oil or walnut oil should be less first and then more, so as to avoid the problem that the pigment in the previous layer is washed off or the picture is too oily to be painted.
Three-in-one oil commonly used in painting is prepared from three oils in a ratio of 1:1:1. In the initial stage, it should be diluted with 1: 3/4 turpentine for drafting, and the proportion of turpentine should be continuously reduced to 1: 2 or 1: 1 in the painting process, so as to ensure that the oil film of each layer is complete even in the process of continuous modification, until the uniform luster is finally formed.
Extended information:
Turpentine, commonly used by domestic oil painters, is a volatile medical oil. In the modulation of oil painting, it plays a role in diluting pigments. Because it volatilizes completely and has no residue after drying, it is suitable for thin painting, which can make the color completely appropriate on the cloth. However, after the oil is dried, the color will reduce the brightness and be slightly gray. In this way, we will talk about color oil. Color oil is a common oil, which volatilizes slowly, and often takes a day or two to dry. If it is completely dry, it will take more than a week. But after the oil is dried, the brightness and freshness of the color will not change obviously, and the picture appears moist and shiny. After the oil is dried, there will be residue and a sense of thickness, which is more difficult to grasp than turpentine. It's best to form it once, otherwise it can't be modified until the oil is dry. If the time is too long, the feeling of the picture has changed. Therefore, turpentine and color oil can also be mixed in a certain proportion, which dries faster and has a brighter color
