umgeschmolzen

Umgeschmolzen is the past participle of umschmelzen in German and is used as an adjective to describe material that has been melted again, or as a nominal phrase referring to such material. In metallurgy and materials engineering, umgeschmolzenes Material refers to metal that has been melted anew to refine composition, homogenize an alloy, remove impurities, or be recast into new shapes. The remelting process typically involves heating the material above its melting point, sometimes followed by alloying, fluxing, and controlled solidification.

The term can also apply to other fusible materials, such as glass, that have been melted and reshaped. In industrial recycling, remelting is a common step to reclaim metal from scrap and produce ingots or billets with a desired microstructure and properties. Metaphorically, umgeschmolzen may describe ideas, plans, or policies that have been substantially revised or reworked, though more common expressions in such contexts include überarbeitet or neu gestaltet.

Etymology: derived from um- (indicating repetition or change) and schmelzen (to melt); the past participle is umgeschmolzen.
