Bismuth crystals can grow in an odd, staircase-shaped, almost pyramid like formation. It has greater growth rate on its outside edges than on the inside edge when it cools making these interesting patterns. Bismuth has one of the lowest levels of thermal conductivity of any metal other than mercury.
