The scarce raw materials considered are antimony, bismuth, boron, chromium, copper, gold, indium, molybdenum, nickel, silver, tin, tungsten, and zinc. Indicative estimates of how long these mineral resources will be available for humanity are calculated, assuming (1)the world population stabilizes...
Excellent thumbnail of this not common native, with a spectacular crystallization of bismuth. Its faces show a metallic white-grey luster, some traces of crystals of quartz are visible somewhere. The specimens of this lot are probably the best found in all the world. Ex Sandro Maggia collection...
Our mineral foundations and natural cosmetics are made without parabens, a group of preservatives linked to hormone disruptions, or bismuth, a chemical compound with properties similar to lead. In fact, we've left out several hundred hard-to-pronounce chemical ingredients, which are still common in...
