Modern food service pewter is tin with 3-8% copper and antimony depending on the particular company that made it.
Chinese manufacture is a crap shoot. They have no morals and will gladly sell just about anything and call it whatever. Take a look at the sticky thread linked in my signature.

I used modern dinnerware pewter today to try and make 16:1 alloy. At a 16:1 ratio my BH was 10.4. It was pretty close to the desired 11BH. I started with 8 pounds of pure lead with a BH of 4.7 according to my lee tester. My modern pewter dinnerware ignots tested 21 BH. So a half pound of pewter was added to the 8 pounds of lead. I tested it with a BH of 10.4. I had to add other 6 oz to bring it up to 11 BH. So it gives you an idea of how to compare modern pewter to tin. I had to basically use almost 2ce the amount to get the hardness I was trying to achieve. About 9 to 1 ratio. I about positive I could have added another 2oz and called it 8:1 and probably would have had the same hardness. I started with adding 2 oz more pewter to the 10.4 BH alloy and it still tested 10.4 BH. From now on I will be doubling my pewter (VS actual tin) in alloy mixes providing it tests at 21BH. So to jump my mix up a half a point in harness I had to almost double it.
