(→Explanation: I've never really called the solder-helping substance anything other than 'flux', probably because it often isn't even Rosin.) |

Rosin (a kind of '{{w|Flux (metallurgy)|flux}}') is one of two parts that make up rosin-core solder, used in electronic work, where the rosin is located in the center (the "core") of the solder. When heated hot enough to melt, it {{w|Soldering#Flux|cleans corrosion and oxides from the surfaces}} of the metal parts to be joined, creating bare metal surfaces that can be 'wet' by the solder. In rosin-core solder, the two substances are touching rather than kept completely separate, since they're both in solid form, and don't react with each other even when they're heated to melt them. In this respect they differ from common combination epoxy chemicals that will be both liquids that cure together on contact even at room temperature. Rosin is also frequently applied to the bows of string instruments like violins or cellos to improve the sound, as immortalized in the famous song "The Devil Went Down to Georgia". |
