What does refusion mean?
Refusion is a rare noun meaning the act or process of fusing, melting, or joining together again. It most naturally describes a renewed fusion after material has previously been separated, melted, or divided. The word is especially applicable to technical contexts involving glass, metals, alloys, or other substances that can be joined by heating and pressure. Its meaning differs slightly from fusion because refusion explicitly conveys repetition: a fusion may be the first joining of two materials, whereas a refusion is another fusion after separation or disruption. Although the prefix re- makes the sense relatively transparent, refusion remains uncommon in ordinary contemporary English and is most likely to appear in technical, scientific, historical, or formal writing. In general prose, a plainer expression such as remelting or renewed fusion will usually be clearer.
nounThe act of fusing or melting together again; a second or renewed fusion.
- The process or act of fusing together again, especially after separation or melting.
"The refusion of the separated glass fragments produced a single continuous pane."
"The refusion of the separated glass fragments produced a single continuous pane."
"The alloy was improved by the refusion of the material under carefully controlled pressure."
The plural is rare, as the noun itself is uncommon.
"Repeated refusions eventually produced a clear sheet of glass."

Where does refusion come from?
Refusion was formed within English by combining the prefix re-, meaning again, with fusion. Fusion derives through French from Latin fusio, a noun based on the past participle of fundere, meaning to pour or melt. The same Latin root also underlies related English words such as fusible, confusion, and profusion.
How refusion is actually used
A rare, formal noun. It is distinguished from fusion, which refers to a fusion without implying that it is a second or renewed occurrence.
