Paper life doubles with every 10°F drop. Fluctuations in temperature and humidity cause fibers to expand and contract, weakening and breaking down paper fibers. In general, the lower the temperature, the better, with a stable temperature recommendation of no higher than 70°F and a relative humidity of at least 30% to 50%. It is recommended that the temperature of the area dedicated to storing paper is lower than that of the user area. Painting is the most common form of restoration and the most common victim. Oil paintings that hang over a long period of time in a foyer or over a home fireplace (paintings in American collections are usually unglazed) will eventually show signs of wear and tear after a few years.
Common problems caused by improper telemarketing list storage, including dust, discoloration, and peeling paint, an environment that is too dry or humid, air pollution, or any other type of contamination can be the cause. e999b3e59c96e4b889 Photo Credit: Taken from Roaming Art History Drew University restores mural damaged by water leak During my work, the most common thing is that the surface of the artwork turns yellow, which is caused by smoking indoors. Smoking indoors will affect the surrounding items, and the surface will turn yellow due to the adhesion of cigarette ingredients for a long time.
However, other issues (such as mold or insect damage) need to be fully explored, assessed and corrected when a work of art is properly restored. In general, the most basic fix is cleaning, usually I start with small parts using a cotton swab. I prefer to use water-based or organic emulsion solvents for clearing. "Cleaning" sounds simple, but it is a science. In the process of clearing the painting, red and green are easier to decolorize. Often, damage caused by improper cleaning may not be immediately apparent, but improper cleaning may reduce adhesion and lead to pigment peeling.
