For example, iron meteorites are frequently made up of one crystal, or lots of large crystals that may be numerous meters in measurement, resulting from pretty gradual cooling in the vacuum of Area. The slow cooling could allow the precipitation of a individual period in the crystal lattice, which sort at precise angles based on the lattice, termed
