Bismuth Metal Crystals in 25mm Acrylic Box

20.00

Many an element collector started out by coming across these little souvenirs bought at museum gift stores or rock shops. The weird Escher-like formations happen when molten bismuth begins to solidify at an uneven pace along its surfaces. As the surfaces collide they change directions at right angles according to its lattice structure and in so doing create the odd-looking walls and stair steps. The iridescence is due to very thin layers of oxidation and are allowed to occur for purely aesthetic reasons; a little thicker here, a little thinner there in each case a different color is produced due to light refraction. To plug this special hole in your set we've put splinters of these beautiful crystals in 1x1 acrylic cubes. They look great on their own or as part of a set in our custom made medium sized Periodic Table of the Elements acrylic cases.
