On the one hand, alchemy has aroused the fascination of many people, and on the other hand, it is a great failure, since no alchemist has been able to make gold or prepare the elixir of eternal life.

In this literary work three major themes are addressed: a) The Environment of Alchemy (What is alchemy and in what ideologies has it been developed?), analyzing its links with astrology, ancient philosophy, metaphysics, occult sciences and New Age, and even glimpsing its profound differences with Christianity, b) The Conception of Alchemy (How is this occult science understood by its followers?), also explaining its foundations and the purpose of the alchemists, and c) Questionings to Alchemy (Why are there objections to alchemy?), indicating its scientific, philosophical and religious refutations.

Finally, although alchemists deny that alchemy is an occult science and use a religious ethics to justify their actions, it is undeniable that alchemy is an occult science, which is questioned, rejected and condemned by the strict Judeo-Christian dogmas.
