Alum. GCs in Alloy

[blackbike]

How would a lot of Alum. gas check in range lead scrap effect my alloy?
Will it skim off, or alloy in?
I have never seen traces when analyzed.
You guys know?
Thanks, bb

They will skim off.

Lead melts at about 650 degrees. Aluminum melts at about 1200 degrees. As long as your temps are reasonable to our hobby you will never melt those GCs and they will float on the lead and get skimmed off.
