On August 10th, the "Kataha Shigehui - National Museum Cultural Conservation Achievement Exhibition" hosted by the National Museum of China opened in the North Exhibition Hall 2 of the National Expo.
This exhibition is divided into five parts: "Industry Pioneers", "Ingenious Skills", "Fantastic Achievements", "Mindful Travel", "Seeing the Past and Knowing the Future". Efforts and achievements have demonstrated the development and progress of cultural protection concepts and technologies.
Restoration and duplication of bronze heavy weapons
The carefully restored first-class cultural relics, such as the kao, the cauldron, and the Geng'er Ding from the Tomb of Fuhao, as well as the replicas of heavy vessels such as the Big Yu Ding and the Siyang Fangzun are exhibited.
Over the years, the National Museum has restored and reproduced a large number of precious bronzes.
In the last century, the National Museum and cultural protection personnel carried out protection treatment on Houmuwu Ding, and completed a series of work such as removing harmful rust, scientific testing, measuring weight and copying the original copy.
Ding ears, four feet, four sides of the body, bottom and inner wall of the vessel are individually remade from silicone rubber molds and glass fiber reinforced plastic resin molds; modern precision casting methods are used to cast replica copper tires; old.
In terms of painting and calligraphy restoration, cultural conservation personnel have combined traditional restoration techniques with modern scientific detection for the scientific protection and restoration of cultural relics. Using light-transmitting photography techniques, they found that penetrating diseases were formed at the partial fractures of the hearts of paintings, as well as traces of previous restorations. and sticker position.
Large-format X-ray fluorescence scanning imaging revealed the distribution of various mineral pigments in heavy-color paintings, providing scientific guidance for the formulation and implementation of restoration plans for cultural relics.
Exhibition of "Smart National Expo" Construction Achievements
According to reports, since the launch of the "Smart National Expo", the National Museum has carried out a 3D digitization project of cultural relics. Using high-precision data acquisition equipment and accurate texture mapping algorithms, the 3D data of cultural relics has been preserved in an all-round way. Use provides strong data support.
The restorer combined modern science and technology 3D printing with traditional craftsmanship, and imitated bronze wares such as the Western Han Dynasty rhinoceros with a wrong gold and silver cloud pattern, and the bronze goblet of the Shang Dynasty Fuhao Tomb, broadening the ways and methods of reproducing cultural relics.
In the research on comprehensive conservation of bronze bismuth in the library, cultural conservation personnel used X-ray imaging, infrared thermal wave imaging, scanning electron microscope energy dispersive analysis (SEM-EDS), portable X-ray fluorescence (pXRF), X-ray diffraction analysis (XRD), Raman spectroscopic analysis (Raman) and three-dimensional video microscopy methods have revealed the historical restoration status of bronze bifang Yi, analyzed the chemical composition and distribution position of the repair materials, and judged the type of corrosion and its stability. The protection and restoration of Yi provides an important scientific basis.
The exhibition also selects a set of early detection instruments, such as hair hygrometer, electric ventilation desiccant meter, etc. The comparison of old and new instruments shows the development process of the National Expo Cultural Relics Protection Laboratory, which is also a microcosm of the development and progress of domestic cultural relics protection equipment. .
The relevant person in charge introduced that since the founding of New China, after more than 70 years of development, the National Museum has continuously increased its investment in cultural relics protection. While improving the level of protection, it has paid attention to the organic combination of traditional craftsmanship and modern technology.
At present, the National Museum Cultural Protection Institute has become a modern cultural relics protection institution integrating the detection, research, protection, restoration and reproduction of cultural relics.
