Sepiolite
/ˈsiːpiəlaɪt/noun
A soft white porous clay mineral, known to pipe carvers as meerschaum.
The Greek roots
Literally: “cuttlefish stone”
The story of the word
The mineral is light, chalky and porous, so nineteenth-century mineralogists named it after the cuttlefish, whose internal bone has exactly that look and feel. σηπία gives English sepia twice over: the animal, and the brown ink drawn from it, which is why old photographs are described by the colour of a squid's defence. Most of the world's supply still comes from around Eskişehir in Turkey, where it is dug out damp and soft enough to carve with a knife.
