Prosciuga

Prosciuga is a traditional Italian technique used in archaeology and architecture for the controlled removal or reduction of moisture, salts, and other undesirable substances from building materials, particularly stone, brick, and plaster. The method aims to prevent deterioration caused by moisture infiltration, which can lead to efflorescence, crumbling, and structural weakening over time.

The process typically involves applying methods such as drying, chemical treatments, or physically extracting salts and moisture from affected areas. This can include the use of absorbent materials, ventilation, heat, or chemical desalination agents designed to draw out soluble salts from porous surfaces. Proper prosciuga treatment is essential in conserving historical structures and preventing further degradation caused by rising damp, capillary action, or environmental exposure.

Prosciuga techniques are often used in the restoration of historic buildings, monuments, and archaeological sites where moisture management is critical to preservation efforts. The approach requires careful assessment of the materials involved and environmentally sensitive application to avoid unintended damage.

While the term "prosciuga" is primarily associated with Italian conservation practices, similar principles are applied globally under different terminologies. The technique underscores the importance of moisture control in building preservation, contributing to the longevity of cultural heritage sites and architectural structures.

Overall, prosciuga is a key intervention in the field of conservation, combining traditional knowledge with modern scientific approaches to maintain the integrity of historic materials against the adverse effects of moisture.
