What is the general protection method for unearthed cultural relics in order to avoid oxidation?

As we all know, most of the cultural relics in the world are buried in places. After continuous exploration and investigation by historians and scientists, their positions were discovered and mined. When cultural relics with a long history are taken out, the unearthed cultural relics are easily oxidized because they are buried in the soil for a long time and do not contact with the air. What are the general protection methods for unearthed cultural relics to avoid oxidation? Take measures in time, suit the remedy to the case, and make corresponding repair plans.

When the cultural relics are unearthed, no effective protection measures are taken, and the cultural relics have been buried underground for a long time, so there will be some water and carbon dioxide on the surface. Once unearthed, due to full contact with the air, the oxidation speed of cultural relics will accelerate, causing certain damage to cultural relics. In this way, the unearthed cultural relics will lose some historical value in the study; Cultural relics represent the characteristics of an era to a certain extent. At present, the study of unearthed cultural relics can effectively understand the development in a relatively long period of time, which is of great significance to modern us, so it is necessary to protect unearthed cultural relics.

Unearthed cultural relics are easy to be oxidized, but scientists must have thought of this problem long ago when they were unearthed, so they will formulate corresponding measures according to the oxidation properties of unearthed cultural relics and protect them in time to minimize the damage, which is conducive to the needs of scientific and historical research; At the same time, for some large-scale historical relics detected, if the current conditions are not enough to give adequate protection measures, scientists will not take unearthed ones, such as the Mausoleum of Qin Shihuang, the Mausoleum of Ganling and the Mausoleum of Yuan Dynasty.

Therefore, under the condition that science and technology are not developed enough at present, if there is no better way to protect the cultural relics to be unearthed, people will not dig them; For unearthed cultural relics, scientists will generally take corresponding measures to ensure the integrity of cultural relics so as to be oxidized.
