Haihtumiskivissä

Haihtumiskivissä, or evaporation stones, are porous objects designed to facilitate the evaporation of liquids. Typically made from ceramic, earthenware, or similar absorbent materials, these stones are characterized by their high porosity, which allows them to readily absorb and hold liquids within their structure. When exposed to air, the liquid then slowly evaporates from the stone's surface.

The primary use of haihtumiskivissä is to add moisture to enclosed environments. They are often employed in humidors for cigars, where they help maintain the optimal humidity level for preserving tobacco. Similarly, they can be used in terrariums or display cases for plants and other specimens that require a specific humidity range. In some instances, they are used in conjunction with essential oils to provide a passive and continuous diffusion of fragrance into a room. The slow evaporation rate ensures a consistent release of moisture or scent over an extended period, making them a low-maintenance solution for humidity control. To use, the stone is typically soaked in water or a dilute solution, and then placed in the desired location.
