<< 11/12 < > A fairly large crystal, approximately 2 mm in diameter. The ambient temperature varied slightly during the crystal growth, changing from about -14 C to -13 C. Note that there is a great deal of structure in the sectored plates at the ends of the arms, reflecting the somewhat higher supersaturation (compared to the pictures above) during growth.
