The infrared and far infrared (10-4000 cm-1) polarized, single crystal reflectivity of the calcium borate mineral colemanite, CaB30~(OH)3"HzO, have been measured at room temperature and at several temperatures below the ferroelectric phase transition at approximately 270 K. Over the entire frequency
