Alchemy - Wikipedia, the free encyclopedia |
 | | The common perception of alchemists is that they were pseudo-scientists, crackpots and charlatans, who attempted to turn lead into gold, believed that the universe was composed of the four elements of earth, air, fire, and water, and spent most of their time concocting miraculous remedies, poisons, and magic potions. |
 | | The best known goals of the alchemists were the transmutation of common metals into gold or silver, and the creation of a "panacea", a remedy that supposedly would cure all diseases and prolong life indefinitely. |
 | | Islamic alchemists such as al-Razi (Latin Rasis or Rhazes) and Jabir ibn Hayyan (Latin Geber) contributed key chemical discoveries of their own, such as the technique of distillation (the words alembic and alcohol are of Arabic origin), the muriatic(hydrochloric), sulfuric, and nitric acids, soda, potash, and more. |
