JIMinPHX, Thank you Sir, I too needed formula for the amount of lead free solder to add.

If you stick the rosin core solder into the melt you will get some spluttering and molten metal may be ejected from the pot

It will smoke to high heaven also. I have a old casting pot that I use and I just put the solder in the pot on a small table top stove and let the stuff cook off. This is done outside of course and down wind. When the smoke stops coming of I take a table spoon and just spoon a spoon full, let it solidify and dump it out. When finished I weigh each one and mark them with a felt pin as to how much they weigh. These are what I add to my regular casting pot. You need .32 ounces for every pound of mix for a 2% mix.

Check your local Walmart or fishing tackle store for lead free splitshot sinkers. They are 100% tin. About three, size 4, tin splitshot sinkers will be just about right to "flavor" two pounds of pure lead. This is not the cheapest way to get tin but is certainly the most precise to get exactly what you want for boolit alloy.
