Question

A philosopher's stone is not exactly a stone. (give reason)​

Answer 1

Explanation:

The philosophers' stone is created by the alchemical method known as The Magnum Opus or The Great Work. Often expressed as a series of color changes or chemical processes, the instructions for creating the philosopher's stone are varied. When expressed in colors, the work may pass through phases of nigredo, albedo, citrinitas, and rubedo. When expressed as a series of chemical processes it often includes seven or twelve stages concluding in multiplication, and projection.
