Of ice obtained by continuous ice systems using metal foil belt, to measure crystal orientation of ice of unstable state. As a result, α angle of one crystal grain mass was confirmed that substantially matches crystal grain boundaries. In addition, it was confirmed that crystal orientation change is due to mutual change of α angle and β angle. If crystal orientation is changed periodically, it was confirmed that unstable state is maintained relatively long. At that time, crystal grain boundary is formed in a sine wave shape, crystal orientation is at apex of grain boundaries α angle of 0 °, and at inflection point β angle becomes 0 °. In addition, α angle and β angle to the boundary of 0 ° + and - back and forth.
