👉 Refolding is a process in which a substance is broken down into its elemental constituents. This can happen through chemical reactions or physical transformations, such as melting and condensation. The result of this process is typically a mixture with different elements. Refolding can occur naturally when substances are heated to high temperatures. For example, iron will refold when it's heated above 1500°C. However, refolding does not necessarily imply that the substance has been completely converted into its elemental forms.
