Bicarbonate

The "smooth water" mineral that builds travertine castles.

Bicarbonate softens water to a silky feel and, over millennia, deposits the white travertine terraces of places like Pamukkale.

Bicarbonate (often with calcium, as calcium bicarbonate) is the mineral that gives thermal water a notably soft, smooth feel and, given enough time, builds landscapes. As bicarbonate-rich water cools at the surface it precipitates calcium carbonate, forming the dazzling white travertine terraces of Pamukkale in Turkey and the Cascate del Mulino at Saturnia. In bathing it is traditionally associated with softer skin and gentle circulation support.
