WebVoltaic pile, Berzelius Museum, Stockholm. Yet another alkaline earth oxide — baryta — had been produced by Scheele in 1774. This earth, named because of its heaviness, had been first observed in “Bologna stone,” discovered in the 1600s by Vincenzo Casciarolo, a shoemaker and alchemist in Bologna. This stone phosphoresced when heated. WebIn 1808, Humphry Davy tried to reduce moist lime by electrolysis, just as he had done with sodium and potassium, but he was not successful. So he tried a mixture of lime and mercury oxide and while this produced an amalgam of calcium and mercury, it was not enough to confirm that he’d obtained a new element.
