I've been toying with making small quantities of bronze just for fun. Tin in raw form has been challenging to find, although I think I tracked down a supplier for small quantities. I have had no luck whatsoever finding elemental silicon in sufficient quantity at a reasonable cost. I did read some interesting articles on properties of aluminum bronze, and have tried a couple of tests there, (see below) and have a good supply of clean/pure copper in cable form that's easy to chop up to size for the (A6 graphite/clay) crucible I'm using. The furnace is propane fired.

I just condensed and converted the biography onto an email system
It also has a full page of tiny print shows, awards and exhibitions but is probably is of little interest. To me at least... all in the past and tomorrow is always an even better day.
