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

|While this looks like a joke entry, this is actually an alternative to resin which is extracted naturally rather than synthesized from other chemicals. Rosin (also commonly known as '{{w|Flux (metallurgy)|flux}}') is one of two parts that make up rosin-core solder, used in electronic circuits, where the rosin is located in the center (the "core") of the solder and helps the solder to melt and bind better, as well as letting it 'wet' the surfaces to be soldered better &mdash; in this case the two parts are touching rather than kept completely separate, as rosin and the solid solder require heat to mix and do their {{w|Soldering#Flux|combined jobs}}, unlike 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".

|While this looks like a joke entry, this is actually a different kind of resin which is extracted naturally rather than synthesized from other chemicals. 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".
