I would not be put-off by copper in the pewter, inasmuch as there are type metals that contain copper (Babbitts and foundry types I believe), and they have made good bullets in the past. I have never heard of zinc in pewter, but I would not rule it out. If it did contain zinc, that would be a problem.ahh I thought this might be a little to good to be true, thanks for the info.
Save your pewter for pouring stuff like butt caps and bolsters for knives.
I guess I will have to test to see how quickly it melts with a propane torch. That aught to make me popular in the used stuff stores...hummm? I wonder if this old picture frame is Pewter?Apparently pewter is used colloquially for some zinc-based alloys that look like pewter.

now that's funny right there!
You don't. As what other alloy's are mix in with the tin blends well with it. So what you get is what you have to deal with in your pot. But there are certain pewter items a caster can scavenge and hopefully not run into unexpected quirks or difficulty with its use in casting. Those little places on earth we hardly ever hear or know about are perhaps the worst when it comes to the blending of unwanted alloys into what they call pewter. Pass over those pieces and keep looking is my suggestion. Old pewter turn of the century stuff. And food service pewter for the most part is considered usable for our hobby. But their are exceptions to the rule also. I hope I answered your question correctly. Any how. Good luck with your quest.so what is the other 15% and how do you get it out so you have the tin and nothing else.
