What is an alchemist?

Alchemist -  is an alchemist was an early student of the science of chemistry. According to one theory the word "alchemy" is derived from "Khem", the ancient name for Egypt. That country was the source of a great deal of the pioneer work in the various sciences.
    Much of the early work of the alchemists is frowned on by to­day's scientists because it was bound up with experiments to find "the elixir of life" and "the philo­sopher's stone" which would turn all base metals into gold. The alchemists also studied magic and astrology.
   However, we have to thank the alchemists for such words as "hermetically sealed", alcohol and alkali, and for the discoveries of sulphuric, nitric and hydrochloric acids, and of metals such as antimony, bismuth and arsenic.
   The "hermetic art" is another name for alchemy. Hermes Tris-megistus was the name given by the Greeks to the Egyptian god of alchemy. Thus hermetic sealing is derived from the method of air­tight sealing used by alchemists in their experiments.
The alchemists also associated the planets with certain metals and used the astrological symbol as a shorthand sign for the metal. The sun stood for gold, the moon for silver, Venus for copper, Mars for iron, Jupiter for tin and Saturn for lead.
