Established over 72 years ago by the inventor of the process of making Methylene Iodide, GeoLiquids supplies heavy liquids worldwide.
GeoLiquids supplies heavy liquids for many industries, supplying our products all over the world. Our liquids are used for SINK / FLOAT gem testing. The density of a liquid determines whether it will float on or sink in another liquid. A liquid will float if it is less dense than the liquid it is placed in. A liquid will sink if it is more dense than the liquid it is placed in.
