Alchemy is an ancient branch of natural science and the medieval predecessor of modern chemistry. Alchemy was an ancient practice originally kept shrouded in mystery and secrecy. Ancient alchemy science was based on theory of transformation of matter with three main goals – to find the Stone of Knowledge ” The Philosopher’s Stone”, to discover the secret of Eternal Youth and Health, and to experiment with the transmutation of metals hoping to turn base metals into gold or silver.
