Abstract
A theory is presented for predicting the size of ice crystals which result from steadystate unidirectional growth within aqueous agar gels Cellular arrays of adjacent ice crystals were separated by an amorphous wateragar membrane at a composition near the vitrification point Using this vitrification composition and both a steadystate condition and a minimum free energy criterion the size of ice crystals was predicted for a given solidification velocity and diffusion condition It was found however that this simple model could not predict the trend towards larger crystal sizes that was observed when the initial agar concentration in the gels increased from 3 to 10 by weight agar
