Identifying, Melting and Casting Bars of English Pewter Metal

Without the time, space or wishing to antagonise my suburban neighbours with the pungent aroma of a backyard foundry, the chances of me melting any aluminium or brass anytime soon seem remote.

However, thanks to inspiration from @Jimmie Porter At Stuart Arts , I decided to scratch my metal casting itch by converting unwanted tankards into round bars of pewter metal.

To the best of my knowledge, everything I've melted down is younger than me, and as far as I know had no historical significance whatsoever. I've no intention of destroying anything that may have any real value.

In this film there's a little bit of history, some safety advice and details of what I've found works well and not so well when re-purposing battered old jugs, teapots and mugs. There are unanswered questions about crystallisation and yellow surface finish that my (fairly unscientific) investigations were unable to resolve.

One thing I forgot to mention for any non-metric viewers is the melting point of pewter is around 450 degrees Fahrenheit, so around the upper end of what you'll see in a domestic kitchen. Not without its dangers, but not too unfamiliar either.

What use are short lengths of 25mm diameter solid pewter bar? Hopefully that will be the subject of a future film...
