Michael -- Am I understanding you correctly that you will make one more affordable set of helmets in silicon bronze and one set in your "special blend" bronze? And that you consider silicone bronze the best commercially available bronze for making a corinthian helmet?
If that is the case, my first question is then: Why would you not use 10/90 tin bronze? I know that this blend is not easily (or at all) available in big enough plates, but if you intend to cast a blank that shouldn't be a problem. As far as I understand it tin bronze is close enough to historical alloys -- while it is also suitable to forge it hot. So my second question is: Have you tried forging silicone bronze hot? Perhaps you intend to cast the blank so close to the final result that you don't intend to use heat.
