I want to know the answer to the following question:
In the original experiment in which the properties of capacitors were discovered, what component acted as the dielectric?
All the background I'm provided with is that "In October 1745, Ewald Georg von Kleist of Pomerania, Germany, found that charge could be stored by connecting a high-voltage electrostatic generator by a wire to a volume of water in a hand-held glass jar.". Is that enough to answer the question?
Answer: yes
