| Sepiolite | Formula | /Images/picture.jpg | Eskisehir Province, Turkey | acquired 2022 | Matrix | Secondary Mineral(s) | From the collection of Jim Daly (5149). Originally named meerschaum by Abrahan Gottlieb Werner in 1788. Later translated as l'Ecume de mer. In 1794, the mineral was called keffekill by Richard Kirwan. Alexandre Brongniart called this mineral magnesite in 1807". The name "meerschaum" translates into "sea foam". Today we only know this as sepiolite. The Turkish material was used for carving smoking pipes and figurines. It forms as nodules in red clay, which are then cleaned and dried and carved. Turkey banned export of the sepiolite nodules in the 1970s to encourage the growth of home-grown meerschaum pipe carving, but only managed to kill off the European meerschaum pipe carving industry. | 3826 | Hardness | Streak | Specific Gravity | Crystal Form(s) |

| Dolomite var. Popcorn Rock | Formula | /Images/picture.jpg | Great Basin, San Rafael Swell Mining District, Emery County, Utah | Collected before 2006, acquired 2023 | Matrix | Secondary Mineral(s) | Like many great discoveries, Popcorn Rock came to the public by accident. As the story goes, the University of Utah geology student Richard D. Barnes had collected fossil corals in 1981 in what he thought was a limestone (calcium carbonate) matrix. He followed a common procedure of placing his specimens in a bowl of acetic acid to free the fossils. This process normally dissolves limestone and leaves behind silicified fossils. But Barnes returned to find aragonite crystals growing from the rock. Instead of limestone, his fossils were encased in a unique type of dolomite (calcium magnesium carbonate). Not all dolomite will produce such “popcorn” crystals, so there must be something unique about that particular deposit’s chemistry. The exact location of the deposit has not been identified; the original label says there are multiple outcrops where it can be found.
