Pedra de Lume means fiery rock and is the salt in a crater of an extinct volcano on the island of Sal. Already in the 19th Century the salt was proftably mined. In the twenties of the last century, even a cable car was built to carry away the salt. Then 25 tons of salt per hour were promoted. End of the 20th Century the production of salt was then set up to minimal house production. Today you can visit as a tourist the salt water to bathe or cover themselves entirely from salt.
