Recalesce

At Stefan numbers greater than 1, the solidification process cannot recalesce the liquid to its equilibrium point and this is termed hypercooling.

One of these has been called recalescence, to which attention was first drawn by Mr. Barrett, who showed that if a piece of hard steel is heated to redness and then allowed to cool slowly it will, when almost black (in a dark room), suddenly reglow or recalesce, and then get dark again.
