Four elements theory

• Adopted from Greek philosophy, particularly Aristotle's work
• Postulated that all matter consists of four basic elements: earth, air, fire, and water
• Each element associated with specific qualities (hot, cold, dry, moist)
• Alchemists believed manipulating these elements could transform matter
• Theory influenced alchemical practices and experiments for centuries

Elixir of life

• Sought to create a substance capable of prolonging life or granting immortality
• Often associated with the philosopher's stone in alchemical texts
• Believed to cure all diseases and restore youth
• Experiments involved complex processes and rare ingredients
• Concept influenced the development of early pharmacology and medicine

Transmutation of metals

• Central goal of many alchemists to transform base metals into gold or silver
• Based on the belief that all metals were composed of the same basic elements
• Involved various techniques such as heating, mixing, and treating metals
• Led to the discovery of new alloys and metallurgical processes
• Concept eventually evolved into modern understanding of chemical reactions
