First you must melt the ice to make it amenable to change (unfreeze). Then you must mold the iced water into the shape you want (change). Finally, you must solidify the new shape (refreeze).

What is the purpose of refreezing?

The objective of refreezing is to stabilize the new situation.

What is refreezing in the change process?

The name of the Unfreeze, Change, Refreeze model comes from the idea of an ice block that needs to be transformed into a new shape. The ice block cannot be forced into the new shape without breaking. Instead, it must be melted (Unfreeze), poured into a mold (Change) and frozen again in the new shape (Refreeze).
