HOW IT'S MADE: Fire Bricks 

He probably wasn't too worried about the camera either ;) The optics alone on such a camera can easily come up in the tens of thousands of dollars.

I worked 28 1/2 years in a brick plant in Pennsylvania. It was called North American Refractories. I am glade that I get a retirement from them.

Why are they gone?

no the camera took the ride not the cameraman

I bet the camera was tied to a string when they let it fall over the conveyor. Other than that, it would have to have been a _pretty_ sturdy camera! Because those things aren't exactly cheap.

@@grayish6963 lol right!? Lol

@@kebman if the camera was tied up, they wouldn't have had to cut the film. The cameraman's arms and legs probably were flailing about as he was falling and got in the shot. Which may be why they continued the shot after the fall. DUH!!!

@@Mike_Greene Yeah, if I were the cameraman, I'd go over the edge myself. It's what cameramen do, after all.

sad to see food being wasted on you.

Im pretty sure he knew exactly what it meant. But like most of his generation, his ambitions where pretty short sighted.

What, did they use up the whole mountain?

because Americans think the world is inexhaustible

It seems less likely that they used up the whole mountain than that making firebrick became unprofitable. Insurance, government regulations (both safety and environmental), pensions, competition from low-cost producers, etc. I notice that Kaiser is now in the medical and medical insurance field. Much more profitable these days.

Ano nymous all of you people like to take jabs at the U.S but fully exploit the products invented here. If you’re so disgusted with us stop using your phone and PC, stop using electricity, and cutting your hair and beard. Don’t just despise us halfway on RU-vid. Go all the way or Shut the fuck up. 🙂

This is decades ago and farther more why does your family call you gifted if your a dum dum

+Gen Maximus yOU NEED A professionally made crucible rated for thousands of degrees if you are taking steel and melting it. If you are making steel check out sand casting Iron- then find a place that sells crucibles- they are made in America- on E-bay a Brit sells them but the cost of international shipping puts his crucibles way out range. basic steel is carbon and Iron. Get on a site where people make iron castings all the time

clay graphite crucible is what you need to melt steel

with out an arc furnace or electric resistance... you cant...in great quantities..gas furnaces barely scrape that temp requirementthe refractory is the easy part
