Lead Testing for content ????

[Hammerlane]

Lead Testing for content ? If you smelted/fluxed and stirred like crazy. The poured your sample lets say, 1 inch square, would the content be some what the same top to bottom. Or would the tin and antimony seperate and move. So when the lead is tested for content the reading may be off.. Real problem I have a big chunk of lead 9 inch high and 8 round and I am sure it stay in a molten state longer than a 1 inch square.. New project I am working on Thanks for the help in advance

would the content be some what the same top to bottom... Yes

Or would the tin and antimony seperate and move... No

Test the hardness over a period of 2 weeks - it will change

The metals will not separate, it is a solution like salt in water and is the same throughout.

Physical impossibility. It's not possible to separate the metals, if you can figure out a way to do that in a home smelting/casting set up you could make millions in the metals industry. The very best you could do is oxidize the metal at the surface in contact with oxygen.
