The main materials and tools of Oil Painting include paint, brush, painting knife, canvas, varnish, and outer frame.
①Pigments are divided into two categories: mineral and chemical synthesis. Most of the original pigments are mineral pigments, which are ground into fine powder by hand and blended when painting. In modern times, it is produced in batches by factories and put into tin tubes, and the types of pigments are also increasing. The performance of the pigment is related to its chemical composition. When toning, the chemical action will cause adverse reactions between some pigments. Therefore, mastering the properties of pigments is helpful to give full play to the Oil Painting skills and make the color of the works last for a long time.
②Painting brushes are made of animal hair with moderate elasticity, and there are types such as sharp round, flat flat, short flat and fan-shaped.
③Painting knife, also known as palette knife, is made of elastic thin steel sheet, which can be divided into pointed and round. It is used to mix the paint on the palette. Many painters also use knife instead of pen, directly Paint or partially create paint layers, textures on canvas to increase expressiveness.
④ Canvas, the standard canvas, is made by stretching linen cloth or canvas on the wooden inner frame, mixing glue or oil with white powder and painting it on the surface of the cloth. Generally, it is made into a base that does not absorb oil and has a certain texture effect, or it is made into a base that is semi-oil-absorbing or completely oil-absorbing according to the needs of creation. The thickness of the cloth pattern depends on the size of the frame, and is also selected according to the needs of the painting effect. The painters who paint the canvas use the canvas painted with the background color, which can easily form a uniform picture tone, and the background color can be exposed inadvertently when painting. After priming, non-oil-absorbing wood or cardboard can also replace canvas.
⑤ Varnish, usually after the Oil Painting is completed and dried, the cover is coated with varnish to maintain the gloss of the picture and prevent air erosion and fouling.
⑥ Outer frame, a complete Oil Painting includes an outer frame, especially for Oil Painting with strong realism. The outer frame forms the limit of the viewer's vision of the work, making the picture appear complete and concentrated, and the objects in the painting are in the viewer's sense. Develop in depth. The thickness and size of the frame depend on the content of the work. The outer frames of classical Oil Painting are mostly made of wood and plaster, while the outer frames of modern Oil Painting are mostly made of metal materials such as aluminum alloy.
