Quartz Geode | Formula | /Images/picture.jpg | Mexico | left in my stocking by an elf, Christmas, 2004 | Matrix | Secondary Minerals unidentified | The label from "GeoCentral, Discover The Wonders Of Our World" reads, "Break-Your-Own Geodes!" and adds "90% of these geodes have hollow centers with crystals. Take a chance! You might be lucky. Geodes are formed from fluids wich crystallize in cavities within the rounded rock or nodule. They are found in many parts of the world. These geodes come from Mexico. HOW TO BREAK OPEN YOUR OWN GEODE I would suggest it is more fun to whack the sock onto a steel plate on the floor than hit it with a hammer. The best way to break geodes is to tape two triangle files to the faces of a large vise. Put the geode betwen the points of the files and close the vise. The geode will crack on a line between the two file points. Wear safety glasses; expect the two halves to fly. |
