As far as we can tell, the stuff had been sold in thin sheets by somebody in Florida for use in re-facing flintlock frizzens back in the 1970’s or 80’s. We’ve got a pretty good idea who it was, but at this point there’s no point in disparaging the dead, so we’ll just leave it at that. The stuff produced a much more vigorous spark bundle with an impressive shower of white hot sparks even with a dull flint.
