What is the best environment for stone relics to be preserved?

Calligraphy and painting, lacquerware, bamboo and wood ivory carving, calligraphy and painting: In ancient times, natural substances such as fir oil, Sichuan pepper, Baibu, papaya, rue, camphor, realgar, cinnamon, and indigo were used to prevent insects, mildew, and protect ancient books. In 1986, the Guangdong Provincial Museum adopted the "821A" jointly developed by the South China Institute of Botany, the Guangzhou Institute of Microbiology and the Guangzhou Institute of Daily Chemical Industry to replace the "p-dichlorobenzene" that has a certain toxicity to the human body, and made calligraphy and painting insect and mildew inhibitors, which have a very good effect, can quickly poison silverfish insects and tobacco beetles, and have a strong inhibitory effect on 62 kinds of molds.

In 1972, the Guangdong Provincial Museum used 15 alkaline sodium tartrate solution immersion method and 20 citric acid solution boiling method to clean and remove rust on a large number of copper coins unearthed in Shunde County, Guangdong, and achieved success, so that the characters, year names and patterns on the copper coins were clearly visible. In 1983, the museum began to use ultrasonic cleaning machines to continue to clean Shunde copper wires, and the efficiency was greatly improved.

In 1975, the archaeological team of the Guangdong Provincial Museum brought back a large number of ancient porcelain tiles covered with coral from the Xisha Islands, and they could not see the words and patterns on the porcelain tiles, which brought difficulties to the identification work. The museum's laboratory, in collaboration with the archaeological team, began with 1:

1. Soak the ancient porcelain pieces with dilute hydrochloric acid to a certain extent, that is, neutralize them with 10 sodium bicarbonate solution, and then rinse them with pure water. This method can effectively remove the coral on the ancient porcelain tiles and reproduce the original text and patterns.

Jade: Just wash it with water.

Do not use any lotion.

Wipe dry with a soft cloth after washing.

It is best to use a soft brush to brush off the dust, if it is not really unsightly, do not clean, so as not to damage the surface of the slurry.
