In ancient times, bamboo slips were an important writing tool, and the quality of their preservative treatment directly affected the preservation of the written text. So, how did ancient people perform preservative treatment on bamboo slips?

Firstly, preservative treatment began with the selection of materials. When choosing bamboo for making bamboo slips, ancient people would select old bamboo with hard texture, clear grain, and no pests or diseases. This type of old bamboo had low water content and was not prone to decay, which was beneficial for preservation.

Secondly, preservative treatment was also applied during the production process. After selecting the bamboo, it needed to be steamed. This step not only made the bamboo easier to flatten, but also killed the eggs and fungi in the bamboo, preventing insect infestation and mold growth.

Then, preservative measures were taken when writing. Before writing, ancient people would soak the bamboo slips in water to allow them to fully absorb water and expand. This not only helped the ink adhere better to the bamboo, but also prevented the bamboo from cracking due to drying during use.

Finally, preservative treatment was also performed during storage. Bamboo slips were usually placed in dry and ventilated places to avoid decay caused by dampness. They were also turned over regularly to prevent deformation due to prolonged pressure.

Overall, the preservation of ancient bamboo slips mainly depended on selecting suitable materials, heat treatment during production, water treatment during writing, and moisture and pressure prevention during storage. Although these methods were simple, they were effective, allowing many ancient bamboo slips to be preserved until today.
