International Museum Day Visits Mysterious Cultural Relics

What kind of treatment will the cultural relics experience after being unearthed? How did its "previous life" get discovered by researchers step by step? In addition to the display of precious cultural relics in the exhibition hall, how are other artifacts dealt with? Yesterday was the annual International Museum Day. In addition to the “Forever North Dynasty Stone Art Exhibition”, the Shenzhen Museum also opened the cultural relic restoration room for ordinary citizens for the first time to show the public the process of relic restoration.

Repairs take a long process. A rusty, incomplete iron sword and a broken bronze bowl lie quietly on the stage waiting for the researchers to repair it. According to Lu Yanling, a research associate of the museum, before putting it into stock This Iron Sword may have to “pass the five generals.”

"This sword is highly corrosive and has many corrosion products. Before it is sealed and protected, it is necessary to remove harmful rust, such as lava and sodium chloride, etc. In order to stabilize it, the single Rust removal is repeated several times." Lu Yanling said, "It takes about half a year to repair the entire process."

This iron sword, which has already been recognized as an unrecognizable weapon, is said to be a Ming Dynasty iron sword unearthed in the Tetuzhai Ancient Tombs in 2000. It is very precious. However, due to equipment and manpower reasons, it has not been repaired, and now it is finally time to "review the sky."

Damaged under the microscope

After the completion of the new museum in Shenzhen in 2008, it has invested more than 8 million yuan to purchase cultural relics repair equipment. At present, more than 200 pieces of cultural relics dominated by pottery have been restored. What steps must be taken to restore artifacts? “The newly unearthed cultural relics will first enter the repair room for preliminary judgment by the researcher, and then enter the instrument room for analysis. According to the analysis results, the treatment plan will be restored by the researcher and repaired. Before entering the warehouse, the cultural relics The material is also partially sterilized in a disinfection chamber, such as wood residue, etc.” Field workers.

Sounds simple, but in reality it is not simple at all. In addition to professionalism, it also requires high-tech means. In the museum room, a body microscope, a three-dimensional video microscope, an infrared spectrometer, and an X-ray fluorescence spectrograph ... the reporter saw the "contest" between artifacts and modern advanced instruments.

A small seal, under the researcher's operation, the distribution of the font color, the depth of each word and a picture is analyzed in 3D form, and the secret weapon of the researcher is a three-dimensional video microscope. As a high-power microscope, it can be enlarged by 50 to 7000 times, so that any small damage on the artifacts is nothing. The more magical thing is that it can also "make" the analyzed data into a 3D effect, so that researchers can detail it. Observe the structure of the artifacts.
