Wilhelm Reich discovered an energy he named Orgone. Using layers of metal and organic materials such as wood, and cotton, he was able to manipulate this energy. To maintain a matrix of these items, they are cast in resin. The unique materials used aids the energy flow within the Orgonite dynamically. It is commonly used as a tool for protection, specifically shielding against electromagnetic pollution or EMF.
