Background

Oil painting pigments originate and develop in europe and have recently become important painting materials worldwide. The egg painting in the European painting produced before the 15 th century is a precursor of oil painting pigments. While egg painting is used, many painters continue to find more ideal condiments and oil paints are in the process of production. Since the beginning of the fifteen century, oil paint has been widely used in various forms. The oil painting pigment is also popular among the painters due to the excellent diversity. Through traditional painting techniques of color mixing, glazing, thick coating, light color and the like, the painting technique can provide an artist with excellent picture effect.

The oil painting pigment is a special painting pigment for oil painting, which is prepared by adding oil and glue, stirring and grinding, and is a painting material formed by molding artistic images on cloth, paper, wood boards and other materials which are used for making bases. It is a substance entity formed by stirring and grinding mineral, plant, animal and chemical synthesized toner and blending agent linseed oil or walnut oil. The color painting tool has the characteristic that the color painting tool can be dyed on other materials or attached to a certain material to form a certain color layer, the color layer has certain plasticity, and various shapes and textures which are wanted by a painter can be formed according to the application of the tool. The various hues of oil paint are determined by the hue of the toner, and oil can function to slightly darker and more saturated the hue of the toner.
