Transcript of Contributions Alchemists made to Science

Alchemists had their own way of doing things in their attempt of scientific methods,but they have grasped the general chemistry techniques, which made it much easier for scientists in the 17h & 18th century
Techniques discovered by The Alchemists
What tools did they discover and use?
Contributions Alchemists made to Science
Conclusion &
Bibliography
So, to conclude everything, alchemy was like the building blocks to science & chemistry. People needed that stage of development to move on to bigger and better things.
Our resources/websites:
The First Periodic Table
Alchemists attempted to arrange information about the substances. This resulted in the first periodic table.
-Alchemists date back to the middle ages
-They study Alchemy, which is a philosophical tradition.
Philosophy; theories
Alchemists have had both mythical &scientific theories.
Alchemy differs from modern science because it includes practices like religion &
spirituality.

What is an Alchemist?
-they've attempted to create the philosophers stone
-they've tried to have the ability to transform base metals into nobel metals (gold & silver)
-they've tried to create a potion that permits eternal youth
Their goals:
-before there were chemists, there were alchemists
-Protoscience
-Used experiments to discover new techniques, substances & tools.
So how does Alchemy contribute to Science & Chemistry?
Isaac newton was a famous physician who was also an alchemist.
He dicovered the theory of gravity.
alchemists attempting to create something
They have made big strides in scientific research sometimes by accident! (ex: they discovered gun powder while they were trying to achieve immortality)
alchemical experiment
Thanks for listening :)

used in alchemy
as a condenser
in the process of sublimation.

-Mercuric Chloride
-Fool's Gold (Iron pyrite)

Also known as the Apothecary Grinder
Apperance: Bowl (usually ceramic or wood), with club shaped pestle.
Use: The pestle is used for crushing or mixing a substance in the martor. Used in masonry and crushing ingredients.
They used experiments to identify new methods of determining unknown substances, analyze the relationship between gas pressure and volume, new procedures etc.
Also known as the Pressure Cooker.
