Of course, these days folks would rather argue ad nauseum about trivia,
rather than get two spark plug gaskets. Anneal one correctly (red heat,
quench in water) and the other incorrectly (red heat and air cool). See
which one comes out clean and soft, and which one comes out black and hard.

So that means that means that wheher the gaskets are annealed or
reused without annealing is irrelevant? That the owner wouldn't benefit
by knowing about using new or annealed gaskets? Come on.

Well, I have learned from elsewhere in this thread that NEW gaskets
are DEFINITELY the way to go since there is debate as to whether the
proper treatment of used gaskets is to include cold water quenching or
ambient air cooling...


Debate aside, the fact is that annealing non-ferrous metals is different
than ferrous metals. Heating and quenching is the way to go for
non-ferrous metals. I have several loading manuals that show this
technique for annealing brass cases (which is mostly copper). You stand
them upright in a tray of water, heat them with a torch and then tip
them over into the water.

Search around on your own and you will find this to be true.
