The growth rates of ice crystals are measured by cryomicroscopic observations for various glass-forming aqueous solutions. The size of ice crystals after cooling and their maximum size during warming is deduced from these rates by integration over the considered thermal range and is expressed as a function of the cooling and warming rates used. The analysis is however limited to the determination of the heterogeneous ice hucleation thermal range which is the critical step in the calculation of the critical cooling and warming rates. The expression of the ice crystal growth rates for glass-forming aqueous solutions is approximated to the expression previously reported by Doremus for crystal growth rates in glasses with a dependence on the viscosity of the solution for high supercoolings. The integration leads to expression involving exponential functions.
