Where Does Marble Come From?

The Mining of Marble. As a natural stone, marble is both incredibly strong and very delicate. It does not split easily and must be mined carefully in order to get sheets of similar size. Explosives can't be used, because the rock will shatter. Instead, minors outline blocks of marble and drive wedges into grooves' openings.
