Title: Patterned ice and its producing method
Inventor: IMAZEKI YASUMASA
IPC: F25C1/24
Filed: 1988-05-26
Abstract: PURPOSE:To hold a patterned shape for an extended period even if it is exposed at room temperature by forming a channel of a desired patterned shape on a transparent ice body and freezing opaquely the ice filled into the channel. CONSTITUTION:A channel 2 of a patterned shape, for example, is carved by an edged tool or is melted to form a corresponding shape by an overheated mold 8. Or the channel 2 is melted by laser rays to form. Re-cooling of an ice body is proper so that the surface temperature of the ice body becomes -10 deg.C--15 deg.C. At the temperature which is higher than the above temperature it is difficult for water filled into the channel 2 of the patterned shape to freeze sufficiently opaquely in a next process. Further at the temperature which is lower than the above temperature cracks easily occur on the ice body when the water is filled into the channel 2. Further it is suitable for the water filled into the channel 2 of the patterned shape to be +3 deg.C-+4 deg.C. Of course in the case of the temperature which is higher than the above temperature the water filled into the channel 2 of the patterned shape is freezed sufficiently white and opaquely, but a difficult point in which cracks easily occur on the ice body is produced.
