How to Perform the Geology Fizz Test without Hydrochloric Acid

Geologists love testing rocks and minerals and, admittedly, one of the most fun tests is the FIZZ TEST. The mineral calcite is made of calcium carbonate (CaCO3).

Hydrochloric acid is the most common acid used among geologists to test whether a rock has any calcite content. In this reaction, the calcium carbonate reacts with the acid and produces carbon dioxide gas, water, and calcium chloride. The carbon dioxide produces the bubbles that you see on the surface of the rock.

Natural Mineral Crystals for Chakra Healing and Meditation

The use of natural mineral crystals in meditation and the healing of a body’s chakras date back hundreds of years. The body has seven major chakra centers through which we gain physical, emotional and spiritual energy. Many people believe that for optimum wellness, it is beneficial to have all of your chakra centers balanced, clear and energized. Each chakra focuses on a specific area of your body and is associated with a different color.

Some Rocks & Minerals May Be Ugly on the Outside but Beautiful on the Inside

t’s easy to pass by rocks and minerals while you are walking around but you never know what is lurking on the inside. Out in nature, the outside of most rocks and minerals look drab and dingy because of rain, wind, ice and snow that will wear away sharp points, dull the vibrant colors and cause cracks in the surface of the samples.

Carnelian is one mineral in particular which looks rather boring on the outside because of this weathering when you break it open to see a fresh surface, you can see vibrant orange colors and sometimes, a hidden surprise.
