This is just annealing copper tube so that a TE backhead can be plumbed in.
What is the process and when do I know its hot enough?
I have a torch and a small hearth, so getting it up to temperature shouldn't be a problem.
It's just the detail I need please.

Heat until it just glows a dark red then allow to cool naturally - no quenching. Best not to do this in bright sunlight as it can be hard to see the beginnings of the red glow.

Thank you. Just never had to do copper before. It's just to take out any work hardening from the process.M.
