Summary

MEASUREMENTS OF THE LINEAR RATE OF ADVANCE OF ICE INTO UNDERCOOLED AQUEOUS SOLUTIONS AND GELS HAVE BEEN MADE. THE SOLUTES CONSISTED OF SUCROSE WITH SMALLER QUANTITIES OF OTHER SUBSTANCES, MOSTLY POLYSACCHARIDES. THE LINEAR CRYSTALLIZATION VELOCITY IN SUCROSE SOLUTIONS IS MAINLY GOVERNED BY THE RATE OF DIFFUSION OF SUCROSE MOLECULES, AND THE ADDITION OF SOLUBLE POLYSACCHARIDES CAUSES ONLY A SMALL EXTRA RETARDATION. HOWEVER, THE GROWTH OF ICE INTO UNDERCOOLED SUCROSE SOLUTIONS IS DRASTICALLY RETARDED AND ALTERED IN MORPHOLOGY BY THE PRESENCE OF A GEL NETWORK.
