Cahnite (Cahnit in German, Cahnita in Spanish, Канит in Russian[3]) is a brittle white or colorless mineral that has perfect cleavage and is usually transparent. It usually forms tetragonal-shaped crystals and it has a hardness of 3 mohs.[4][5] Cahnite was discovered in the year 1921.[3] It was named Cahnite to honor Lazard Cahn (1865–1940), who was a mineral collector and dealer.[4] It is usually found in the Franklin Mine, in Franklin, New Jersey,[5][4] but has also been found in Japan[6] as well as in the Vallerano quarries in Rome, Italy.[7] The geological environment that it occurs in is in pegmatites cutting a changed zinc orebody.[3][4][5] The chemical formula for cahnite is Ca2B[AsO4](OH)4.[5][8][9] It is made up of 26.91% calcium, 3.63% boron, 25.15% arsenic, 1.35% hydrogen, and 42.96% oxygen. It has a molecular weight of 297.91 grams.[5] Cahnite is not radioactive.[4] Cahnite is associated with these other minerals: willemite, rhodonite, pyrochroite, hedyphane, datolite, and baryte.[3]
