Which chemical is called philosopher's wool
Answer : Zno
The compound zinc oxide (ZnO) is called philosopher's wool. As a ritualistic ceremonial part, the Alchemists would burn zinc in air and collect the residue, which formed into white woolly tufts.
Alchemist’s started calling this white woolly residue as ‘lana philosophica’ in Latin, which means philosopher's wool in today's life.
