👉 A stone fluid, also known as a pseudofluid or pseudosol, is a complex mixture of water and dissolved mineral particles, often with a gel-like consistency. These fluids are typically found in natural environments like hot springs and geysers, where they form when groundwater rich in minerals comes into contact with steam or heat. The dissolved minerals, such as silica, calcium carbonate, and iron oxides, give the fluid its characteristic appearance and properties. Despite being a fluid, stone fluids exhibit solid-like behavior under certain conditions, such as high viscosity or low temperature, making them behave more like a solid. This unique combination of fluid and solid characteristics is a result of the interactions between the water and the mineral particles suspended within it.
