External alchemy, often referred to as alchemy, is a historical practice focused on transforming base metals into noble metals, such as gold. This process involved various techniques, including heating, mixing, and distilling substances, with the goal of achieving material perfection. Alchemists believed that through these transformations, they could uncover the secrets of nature and the universe. In addition to material transformation, external alchemy also aimed to create the philosopher's stone, a legendary substance thought to grant immortality and the ability to transmute metals. While external alchemy is often viewed as a precursor to modern chemistry, it also held spiritual and philosophical significance for practitioners, who sought to understand the deeper connections between matter and the cosmos.
