Bob I seem to remember back in yr7 at HS quenching in oil is this the preferred option or am I dreaming. Anyone else?
And Im thinking if I try this maybe the open fire might be a good place to get the gasket uniformly hot. How do you do it? As I said earlier I have not had much luck with used coppers in the past but the consensus is in favour so I might give it a go. As yet I have not had the head off and curiosity is eating away at me. And I do like to pull things apart.

just let it cool down slowly enough so you can hang onto it in your hand, then put it back together.
golly.

Kato is near spot on, anealing is heating up on a gas burner until it glows red then drop it in cold water or you can let it cool down naturally it doesnt matter which way.
yep BB has got the way and i have always done it the same way and never had a prob cheers jase |

I am a plumber and work with copper allday. heat gasket with gas torch a nice even red let it cool. no need to quence non-ferrous metals, it is quite thin and you will be able to handle it after about a minute. Ferrous metals are quenced with water or oil for hardening.

The advantage of quenching is that the oxides that form during the heating process plus any carbon left on the gasket fall off due to the rapid drop in temp.
