Oh, they probably just noticed one day that the two are almost nothing alike each other, and that you'd have to be an idiot to fail to identify them as separate materials. Ever seen gold leave a big black streak when dragged across a surface?
And the compound you're referring to is called iron pyrite-- "fool's gold," is a nickname. It's called "fool's gold" because you'd have to be a "fool" not to be able to tell it apart from gold. Otherwise they'd probably call it something like "nearly gold, almost anyone could fall for the similarities." But they don't.
The alchemists would not have known streak-plate tests or compounds like iron pyrites as that, but they might have picked up other characteristics, such the ease or otherwise of melting the two materials. Remember that alchemists were not scientists as we would accept, but empiricists who worked on random guess-work in searching for that which cannot exist.

I goggle these things to find out not answer!
Paracelsus introduced the concept of "disease" to medicine, however rejecting the idea that disease is a matter of imbalance and disharmony in the body. He claimed that disease is caused by agents outside the body attacking it. This was long before viruses and bacteria were discovered.Trimble, Russell, "Alchemy," in The Encyclopedia of the Paranormal edited by Gordon Stein (Buffalo, N.Y.: Prometheus Books, 1996), pp. 1-8.
An alchemist was someone who looked for the secret of life, in order to try and find a way of living forever. On the way to finding that they looked at whether you could change one thing into another. The most well remembered of these experiments was about whether you could change base metals (like lead) to gold.
There are no difference between htm and html. Occasionally, people would drop the L since both are accepted. Certain types of computer will find it confusing if one does not include the L at the end.
"Find" is used to discover the location of something or someone, while "find out" is used to obtain information or discover a fact. "Find out about" is used to gather details or information about something or someone.
Nothing. They didn't have the technology at that time to know about the existence of atoms.
you can find it at the April fools party

they have no difference...... I'm adding on to that... They do have a difference..... FIND is present or future tense, and FOUND is past tense.
The difference (greater minus lesser) is the distance between them.
To regroup 4 tens in 341, change it to 3 hundreds and 14 tens. Then, subtract 2 hundreds and 2 tens from 3 hundreds and 14 tens to get the difference. The difference between 341 and 228 is 113.
A quadratic sequence is when the difference between two terms changes each step. To find the formula for a quadratic sequence, one must first find the difference between the consecutive terms. Then a second difference must be found by finding the difference between the first consecutive differences.
