Alum stone is a natural mineral which typically occurs as encrustations on rocks in areas of weathering
and oxidation of sulfide minerals and potassium-bearing minerals. Alum Stone by Verdan is just that, a 100% natural deodorant made from the highest quality odor fighting minerals, sourced from the far corners of the World.
At Verdan, we take care to use the best part of the mineral by selecting our products from the heart of the crystal, where the mineral is the purest. Through this natural process, the result gives us a certified extra-pure Kalunite™ mineral ready to be used in our formula and products. As nature has provided a solution to preventing odor, our high-quality minerals provide a deodorant that releases nature’s secret, and the result is incredibly effective.
Alum occurs typically in large deposits located throughout the world in areas of volcanic activity where formation is a result of steam and hot gases venting from fumaroles and interacting with argillaceous rocks. It appears as a translucent, crystalline stone and is colorless and glassy (vitreous).
