The paintbrush is composed of three parts: pen holder, metal hoop and the brush hair. The key to the quality of paintbrush is in brush hair. When you decide to buy a brush, please carefully make sure that the brush hair is smooth, natural, and uniform. Also it should not be pruned. The paintbrush sold in shops is usually glued together and not diffused through separation by hands. At the same time, to see whether the metal hoop is solid. A transverse wave is good. The last is to see the brush in your hands is comfortable. If kept properly, the paintbrush can prolong its service life. Brushes should be cleaned after use to prevent the paint dried in the brush hair. If the paintbrush is not used for a long time, do cleaned thoroughly and make it archived by paper not only on landscape oil painting. If in a short time, you can use a cloth or paper to wipe away the extra paint in the brush and then clean it with turpentine and make it soaked in water. Two turpentine jars (if the sauce bottle) can be prepared to use turpentine to clean the brush. The first jar is used for a preliminary cleaning and removing remaining pigment of the brush. Another is for a second cleaning. Thorough cleaning methods include: Firstly, after cleaning with turpentine, use the pen dipped in water or warm water on the soap friction (Note: boiling water can not be used because boiling water is harmful to the metal hoop of the brush). Secondly, press by a finger or rotate the brush hair in the hands. Thirdly, repeat the above actions until the soap turns white. Finally, after the rinse with water, straighten out the brush hair and pack up with the slightly harder note for storage and for later use. When cleaning brush, pay attention to the appropriate strength, otherwise it is easy to hurt the brush hair. The soap liquid must be alkaline soap (foreign countries have special brush cleaning soap), to prevent the brush hair hardening. You can use the silk wool detergent and not use paint thinner which will make the brush lose oil to become embitterment. The worn down paintbrush will usually be lost. If the metal hoop is heated on the flame, pull out the brush hair without changing the size of painting brush can prolong the service life of the brush, which is not only energy saving, but also interesting.
