[[Bentonite]], [[perlite]], [[pozzolana]] and small quantities of [[kaolin]] are actively collected via [[strip mine]] or [[open-pit mine]] techniques in Milos and sold all over the world. In the past, [[baryte]], [[sulfur]], millstones and [[gypsum]] were also mined; [[Pliny the Elder]] notes that Milos was the most abundant source of sulfur in the ancient world.<ref>C.

The Melian earth was employed as a [[pigment]] by ancient artists. Milos was a source of [[obsidian]] during the Neolithic ages for the Aegean and Mediterranean.
