Catlinite (red clayey shale) carved
Donation of Missioni Cattoliche Americane, 1893 (?)
The catlinite was found only in the Pipestone quarry in Minnesota (now Pipestone National Monument). As soon as it was extracted, it was easy to work: to make the holes for the tobacco and for the storing of the torch, a wooden reel was used, rotated with a bow, gradually introducing abrasive sand and water into the hole.
