Abstract

A method of preparing beads from a molten or liquid substance, characterized by introducing a stream of the molten or liquid substance into a liquid medium that is not miscible with the substance and is maintained at a temperature below that of solidification of the substance and shear the current of the substance to form droplets and initiate its crystallization.
