Interesting documentary (in Portuguese) about a Gunpowder factory in Rio de Janeiro, Brazil, named as "Fábrica da Estrela", it still exists and now is property of IMBEL (military industry of Brazilian government).

I don't speak Portuguese but this is a really cool video. I enjoy seeing the milling process of different manufacturers.
