How Glass is Made

In general, the production of stuff is pretty awesome to watch.

The act of sand becoming glass, however, is just a miracle.

I really like this video because it starts with sand in silos and follows the process through the furnaces - with very, very slow melting - onto liquid tin and onward through the annealing oven.

• Along the way (at 4:35, to be specific), we get to see how flexible the still-hot-but-solid glass is.
• Please tell me, though, that at 0:55 he didn't call sodium carbonate and calcium carbonate elements. Maybe he just means 'ingredients' not truly 'elements.'  Language matters, dude.
• At 5:15, they 'haul glass'...it's a funny, doncha see, boy, a funny...
• They show off some fashionable kelvar suits at 5:35 to - as they say at 5:50 - protect your...uh...leg areas.

You can see an animation of the process after the jump...
