What happens when bronzes meet lasers? It‘s a wonderful collision.
China has a long history, and there are countless cultural relics buried under this land, especially bronze wares, which are extremely characteristic of the times. There are many bronze wares discovered in archaeological excavations. The cultural relics unearthed in Sanxingdui, China are mainly made of bronze, jade, pottery, ivory and other materials. Bronze cultural relics have undergone long years of erosion, and the cultural relics themselves will inevitably be contaminated, corroded, stained with mold, and rust. These "historical imprints" are imposed on cultural relics, bringing great trouble to ancient cultural relic workers. How to clean and restore bronzes is a problem that archaeologists attach great importance to.
How to restore their glory thousands of years ago?
Traditional dry cleaning, water washing, mechanical dust removal, drug cleaning and other methods inevitably require contact with cultural relics during the operation process, which will cause irreversible damage to cultural relics if they are not careful, which will greatly test the meticulousness and patience of ancient cultural relic workers.
With the development of the times, the introduction and application of a new generation of technology is essential. According to the basic principle of “less intervention, less intervention, and reversible protection and treatment” for cultural relic protection, the new laser cleaning technology has begun to be valued by experts in the cultural relics repair department. Compared with traditional cultural relic restoration methods, laser cleaning has the advantages of dry, non-contact, gentle and strong degree of freedom. After setting the laser parameters of the corresponding material, the laser beam can efficiently and accurately remove the deposits and oxidation on the surface of the cultural relics. It can better restore the original appearance of cultural relics. This is also the most important progress of contemporary archaeology - integrating advanced laser technology into archaeological work, adding the power of science and technology to the restoration of cultural relics, showing the style of cultural relics more realistically, and preserving the style of cultural relics more gently.
At present, laser cleaning has proven to be an effective cleaning method for copper, iron, wood, pottery, bronze, stone tools and paintings.
The cleaning of bronze cultural relics is one of the most important problems encountered in the current cultural relics protection work. Bronze artifacts unearthed after archaeological excavations often have thick and mysterious green rust on the surface, most of which are harmful rust that can spread and spread, and must be removed as soon as possible. Laser cleaning can give full play to the advantages of non-contact dry cleaning at this moment. By controlling the energy density of the beam, the rust stains can be removed cleanly and refreshingly without harming the cultural relics.
In addition to bronzes, stone carvings and murals are also the scenes where lasers show their skills. In the restoration of cultural relics such as marble carvings, tomb bronze statues, medieval oil paintings, and ancient architectural murals, laser cleaning has been proven to be the most gentle and effective method. Through the precise adjustment of the laser intensity, the surface dust and deep attachments can be removed without damaging the cultural relics, and the original appearance of the cultural relics can be restored.
With the rapid development of laser technology, high-precision laser cleaning has been able to adapt to the work requirements of various occasions.
