1, long-term illumination
Long-term exposure is one of the main reasons for the fading of relief paintings. Ultraviolet rays in light will destroy the molecular structure of pigments and dyes, making them gradually lose color. In particular, strong direct sunlight will have a more serious impact on the picture. Therefore, putting the relief painting away from direct sunlight can slow down the fading speed.
2. Exposure to oxygen and moisture in the air
Oxygen and humidity in the air can also cause the relief painting to fade. Oxygen reacts with chemicals in pigments, leading to oxidation and fading. The environment with high humidity will accelerate the flow and oxidation reaction of pigments and darken the picture color. Therefore, keeping proper humidity and ventilation in the storage environment of relief paintings is one of the important measures to reduce fading.
3. Improper use of cleaning agents or chemicals
Improper use of cleaning agents or chemicals may also cause the relief painting to fade. Chemical components in some cleaners and chemicals may react with pigments on the screen, causing the pigments to fade or change. Therefore, when cleaning and maintaining relief paintings, we should choose a special artistic cleaner or carry out the correct cleaning method according to expert advice.
Preservation skills of relief painting;
1, keep dry.
Relief paintings are very sensitive to humidity, so they should be stored in a dry environment. Avoid exposure to humid air to prevent flowers from becoming moldy or deformed due to humidity.
Step 2 avoid direct sunlight
Prolonged exposure to the sun will fade the flowers. Therefore, relief painting should avoid direct sunlight, and it is best to put it in a place away from light.
3. Use a dust box or frame.
In order to protect the relief painting from dust and dirt, the relief painting can be placed in a dust-proof box or in a transparent glass frame. This can reduce the risk of contact and weathering.
4, regular cleaning
Use the low temperature setting of a soft brush or a hair dryer to clean the surface of the relief painting. Gently brush off dust or subtle stains, but be careful not to damage the flowers or cause displacement.
