Gypsum Crystals at the Plaster Museum

One of the highlights of the Plaster Museum is its collection of a hundred gypsum crystals from around the world. This collection showcases the crystallographic diversity of gypsum, with examples such as sugar gypsum, lark's foot, spearhead, and fibrous in flakes. It also reflects the geographical diversity of gypsum, demonstrating how this mineral is found in various regions across the globe.

Archives at the Plaster Museum

The Plaster Museum holds an extensive archive of more than 1,500 documents and iconography. These resources provide valuable insights into the history and development of plaster companies such as Plâtres Lambert, Poliet Chausson, SAMC, and Plâtrières de Grozon, which eventually led to the creation of Placoplatre. The archive also includes information on Mussat Binot, Gypses and Plâtres de France, and Plâtres Lafarge, which later became Siniat.
