Square pillar or block ice having a beautiful striped pattern is made by cooling and freezing raw water for ice making in an ice can, the raw water containing at least one soluble material and being subjected alternately to a degree of agitation effective for forming a transparent ice layer and to agitation required for forming a semi-transparent ice layer, thereby forming a striped pattern of the semi-transparent ice layer.

Method of making ice having a striped pattern and an apparatus for

Ice, in particular, block ice containing soluble materials dispersed therein is produced in an effective manner on a commercial scale by a process comprising cooling and freezing raw water for ice making in an ice can while air blowing and agitating by a blowing means, characterized by adding and dissolving soluble additives or materials in the raw water, effecting the air blowing and agitating with air under a pressure close to a minimum pressure required for dispersing bubbles in the raw water and thereby dispersing and incorporating the soluble additives or materials in the ice without substantially deteriorating the transparency of the ice.
