In 1669 German merchant and amateur alchemist Hennig Brand attempted to create a Philosopher’s Stone; an object that supposedly could turn metals into pure gold. He heated residues from boiled urine, and a liquid dropped out and burst into flames. This was the first discovery of phosphorus.Добавлено на ленту времени:
