Stop being faggots and just filter the derailing trolls. Your off topic engagement shits up the thread just as bad as they do.

Since pure lead is slightly heavier than silver, an alloy would likely be used, with lead and another metal such as tin. That way, the density would match that of silver. Silver has a specific gravity of 10,490 kb/cuM, and lead has a specific gravity of 11340 (for reference, gold is 19320, platinum 21400, tungsten 19600, copper 8930, tin 7280). Lead is 8.1% heavier than silver. Tin is 30.6% lighter than silver. Using a trial-and-error computer program we come up with 79.075% lead and 20.925% tin (lead's 11340*.79075=8967.1, tin's 7280*.20925=1523.34, add them and you get silver's 10,490). Rounding to 80% and 20% gives you a specific gravity of 10,528, or 0.3% higher than silver, which is close enough to work with.

So if it used a tin-lead alloy, it would likely be exactly 80% lead and 20% tin.
