    Somehow I never though that slag floats on molten metal and it’s enough to puncture the bottom to get clean metal. We are used to believe that people in the past were stupid and uncultured, but it’s obvious they were equally intelligent and smart.

      We are the same humans, just with different tools and cultural backgrounds. Personally i love to imagine early eocene humans going about their day and coming up with clever solutions for all kinds of tasks.
