You may be right on the Minolta, they have made some fine lenses. When you say crucibles I assume you mean glass. Minolta starting making its own in 1942, Nikon in 1917. Pentax uses Hoya glass as does Leica for some lenses. Glass melting is far from common these days and many buy glass blanks from the larger manufacturers since it is cheaper than manking it themselves. Canon never indicates they do their own glass manufacturing and not that it matters, but I would not be surprised if they use Hoya glass too.
