[quote=drwelby]That’s pretty good for your first run.
black shit = burnt flux = too hot
coppery colored edges = too hot
pits can be overheating but also can be impurities and other shit.
be careful comparing your technique to pros because many of them run gasfluxers which totally changes the game.[/quote]
coppery colored edges = too hot <<< not too sure what this means, do you see it in the pic above? is it the little dots of splatter on the edges?
I did not clean up the tubes well for practice so I will look out for that later. I was trying to do the bare minimum necessary for things to wet out.
Can you elaborate a bit about the differences I would expect to see if someone uses gasfluxer?
