In this paper, knowledge of the viscosity of volcanic rocks at 800 to 1400℃ is discussed whether there is any significance to be attached to the experimental results in order to obtain a better understanding of some matters related to the restoration of rocks to the viscosity possessed at or before the time of extrusion.
