Newb desparate for help with soldering copper

[Radioman]

When soldering, you can't overheat a joint. I'll get stick for this but I have proof

Yes you can. Heating copper pipe and then rapid quenching will make the copper soft as butter. Try this. Heat copper pipe to cherry red the quench in cold water. Now try to bend. It be bends like rubber. Now beat with a hammer. Now try and bend. Copper work hardens.

Said proof, it may get brittle as stated above (I thnk) if you 'quench' it, who knows...

American solvent glue has colour in it so you can see where it has been applied. The pipe is some kind of pressurized solvent weld water supply service. Like a modern durapipe.
