 · The gold can take on different forms (ore, ingots, coins, etc.), but in itself it is ultimately unchanging. Similarly, we should not deny or fail to perceive that ordinary reality appears to consist of distinct, persistent individuals. However, we must realize that there are not actually distinct, persistent individuals. All that really exists is the complete network of mutually interdependent ...

Mineral Deposits

The product of the copper mines on Keweenaw Point, Lake Superior, was, and to a great extent is still, called copper rock rather than copper ore, and native gold in quartz is often described as gold quartz rather than gold ore, but these restrictions are gradually disappearing. An ore may therefore be defined as a metalliferous mineral or aggregate of metalliferous minerals mingled with a ...

One point now must finally be made clear; alchemy does not mean the art of making gold or silver, or precious stones for that matter, since these latter are also possible by the same processes, for man cannot make or create anything that is nature's work.
