....flux.

I know that you have to use it when using solder ring or end feed fittings,
but what exactly is it & what does it do?

Just curious.

IIUC flux prevents burning on the metal surfaces (solder would not adhere
well where there is oxidisation) and aids the solder in spreading out.

Keeps the metal chemically clean and prevents it oxidising. This enables
to solder to "wet" the surface of the metal.

rips teh oxides off the metal you want to solder to so it flows and
makes a surface (alloy? amalgam?) anyway, its the oxide ripping part
that makes it work

It's a form of acid, cleans the copper giving a better seal with the solder

Plumber's flux maybe, electronics people use "non-acid flux" and I've no
idea what it is.
