What does «piedra filosofal» mean in Spanish?
- The material with which the alchemists intended to make gold artificially, among other properties. The philosopher's stone or stone of the philosophers (Latin: lapis philosophorum) is a legendary alchemical substance capable of converting common metals such as mercury into gold or silver.
