Minerals The Age of Discovery

green malachite mineral

In the 18th and 19th centuries, there was a great deal of interest in mineralogy.

Some collectors travelled all over the world searching for rare and impressive specimens to add to their collections. Many were attracted to Cornwall because of the great number of mines and the remarkable variety of minerals they produced.

Your data on the Azurite page says: "Data Panel: Iron Sulphide: Azurite" But azurite is iron carbonate, not sulphide (as shown by your correct formula).

Re my previous comment - I should have said azurite is copper carbonate! Now we've both been wrong! ............ GEEVOR REPLY: Thank you for pointing our typing error out to us Peter, we have now amended it above.
