• 主な応用

  In addition to its architectural and decorative applications, pumice also has various uses in the personal care and beauty industry. It is often used as an exfoliating agent in soaps, body scrubs, and foot treatments to remove dead skin cells and promote smooth and soft skin. The abrasive properties of pumice make it effective in removing calluses and rough patches on the feet.
  Moreover, pumice stone is commonly used in the horticultural industry for the preparation of soil mixes. Its porous nature allows for adequate drainage and aeration, preventing waterlogging and providing a favorable environment for plant growth. Pumice is also frequently added to bonsai soil mixes to enhance the drainage abilities of the soil.
  In summary, pumice stone is a versatile material that finds utility in a wide range of applications. Its properties as an abrasive agent, insulator, and lightweight aggregate make it valuable in industries such as construction, personal care, horticulture, and decoration.
