Explain the Seasoning of Stone

Seasoning of stone can be defined as a cyclic two-step process, with the first step consisting of drying and wetting cycles and the second step comprising proper airing of stone. This process is done before using the extracted stones for building purposes because their properties tend to alter when they are brought out into the open environment. The stones have natural moisture called quarry sap which makes them soft enough to be workable.

Usually, stones are extracted from a depth where they remain under heavy loading, high pressure, anaerobic conditions, moisture-free, etc. On extraction, changes begin to occur in its internal structure due to a reduction in load and pressure and an increase in surrounding moisture. It undergoes both chemical and physical changes, especially as a result of the reaction of the minerals it contains with moisture.

Therefore, stones need to be properly seasoned to maintain or improve structural strength. Stone seasonings generally help the surface carbonization of stones, the redeposition of invading minerals, the deposition of minerals on the surface of stones, the evaporation of water, and the addition of water.

In general, dehydration of stones in seasonings is an irreversible process that makes stones more durable. Seasonings are usually made with soft limestone, not hard limestone, which does not appear to be affected by the seasoning.
