This is going to take some time
But are you saying if I have a bar of zinc and a bar of lead and each bar is same size the density can be measured with water displacement on the graduated scale ?
Interesting if some thing can be that sensitive

From what I have read there is a Zinc known to be pure
then a zinc known as (Good Ordinary Brand) that has about 2% lead
It's my hunch that NOW with lead laws getting strict WW saying ZN are proper
But if you study WW you will notice some have no letters telling you ZN
so I feel there are WW out from a few years ago that were made with Lead Zinc alloy as it was not a concern then.
I can confirm some ZN wheel weights are hard as rock and some wile not like lead are a little softer
only 5% Zinc is Ideal for Amo If the amo is going to be use fast. I have read amo with zinc does not age well ( but this is stuff from other forums so ....)_ . But as mentioned some large caliber Amo is very pleasing to shooters when it's a 50 50 mix
so zinc with lead will find a home with Amo people (some)

A complete separation of zinc from lead can be achieved by distillation

Yes, weigh your sample in grams then find out how much water is displaces in milliliters. Dividing your weight by your displacement will give you your density. I would think a postal scale with accuracy plus or minus 1 -2 grams, a container marked so that you can read volume to the milliliter and a sample of about 100 grams should give you a fairly accurate result.
