Which preservation method uses a desiccant to control moisture?

The preservation method that utilizes a desiccant to control moisture is indeed dry preservation. This technique is crucial in preventing the deterioration of materials sensitive to humidity. By using desiccants—substances that absorb moisture from the air—dry preservation effectively creates a low-humidity environment, which helps inhibit mold growth, degradation, and other moisture-related damage.

In the context of preservation, maintaining a controlled environment is essential, especially for items like documents, textiles, and certain artifacts that can be adversely affected by excessive moisture. The use of desiccants is a common and effective strategy to achieve the necessary dryness, ensuring the longevity and integrity of preserved materials.
