Is anyone here by chance familiar with working with pewter?
I saw some lovely jewellery at a gift shop the other day that had been cast in pewter and as usual I started contemplating some new ideas.... At first glance they look like silver but of course they must cost considerably less for materials.
I know pewter is very soft and wouldn't be soldered with a torch, instead a soldering iron and a soft solder of some sort. I'm wondering whether it could be used in a polishing tumbler with stainless steel shot and whether usual oxidising chemicals can be used on it.

Are there any other major drawbacks using pewter?
