I started casting this past year with good results so far. I was smelting wheel weights ,sinkers that were cast from WW and some bullets with gaschecks still attached. I figured I would scoop out the checks along with the ww clips. Plenty of clips but no gaschecks were found. So the GC are in the melt ,good, bad or ugly?

gas checks will come out with the other debris when the melt is fluxed. Stir well, flux, remove, should be good to go.

Checks were most likely stuck in the clips where you couldn't find them.

GC boolits put alone in the pot will always have the check rise to the surface

yea the GC's turn color and are really hard to find in all the c.r.a.p. and trash.

no they didn't "melt" into the lead. :)

foxtrapper - I once put about 50 boolits with GCs in the bottom of an empty pot and added ingots to fill the pot. It took a lot of fluxing and stiring to get all of the checks out. I didn't count them but each time I would ge one or two more. I just kept fluxing and stiring until I didn't get any more.

10-4! Thanks guys. Just for the heck of it. How hot would the melt hafta be to melt the copper checks?

Well over 1900 degrees F to melt pure copper! Other factors come into play depending on the alloy the checks are sitting in .

Yeah you aren;t smelting hot enough to melt gildign metal. They are there in the debris.

Sometimes they stick to the walls of the melter.

Yep......been there done that. You think you have them all out but when you stir the pot, ups pops a couple more.
