softening lead by removing alloy, possible?

Thanks for responding to this. Depending on memory is sometimes risky!

And Thank You again for the service and info that you provide to the members here.

From my limited metallurgical background you cannot separate the alloys out as the lead tin antimony go into a true solution and DO NOT separate. Reference the Lyman Cast Bullet Handbook 4th edition. The metallurgist they had talk about the metallurgy side of this goes into depth and confirms that the alloy does not separate out. Tin does not float to the top. Both lead and tin oxidize when exposed to Oxygen. Melting the oxide does not normally break the extra molecule of Oxygen away, takes some serious foundry practices and equipment to do.

Only solution to soften the alloy is by diluting.
