if you're ever near Corning NY, stop by the CMOG (The Corning Museum of Glass) lots of cool tech & art stuff including the 200-inch Palomar mirror blank which was then the largest mirror at that time.
I recognized the one photo of the glass plant. Corning Glass Works. Saw the credits confirming it. I was born about 2 blocks away from that plant in Corning NY. All the old plants are pretty much gone now. Just corporate headquarters and a big R+D facility. When it was booming during the war my great aunt, her daughter and granddaughter all worked there. They had their photo taken for wartime news for 3 generations of women working for the war cause. Most all my relatives worked there. My dad worked there before he went in the Navy in the late 50’s but ended up working for Westinghouse in Horseheads NY making picture tubes until they closed in the late 70’s.
This reminds me of when my mother set a casserole dish of her five cheese pasta on the dinner table and within moments the dish exploded. We ended up eating out after a couple hours of cleanup. (Update: Asked and yes it was Corning Ware)
@@zefallafez , in the 1960's when I was about 10 I tried to heat a casserole dish of leftovers that came out of the fridge on a gas stove. It shattered and made quite a mess (pieces of the dish melted the kitchen carpet). Obviously this was long before we had a microwave oven.
Wow, I remember watching 16mm films like this in school! Even in the mid-late 1990s, sometimes we'd still watch films like these on those institutional Eiki projectors. I've always had a soft spot for their mono, optical soundtracks and endearing propensity to be destroyed during viewing. I vividly recall the last 16mm film I ever watched: "Why Man Creates" by Saul Bass, which I screened in 2000 with this brilliant girl from one of my philosophy classes whom I had a crush on. The librarian set us up in a private screening room, turned the lights out, and left. I appreciated that. ;) EDIT: Great job transferring it, btw! I suspected you'd cleaned it up, but not to that extent! That reminds me of a joke I heard long ago: Where's the place you're most likely to see pink elephants? In a Ted Turner colorized movie!
I wonder where that factory at 2:41 is. It does not match the orientation of the street grid with the current Corning, NY plant, nor any of the plants in Charleroi, PA.
Definitely interesting, both with vacuum tubes and lab glass in mind. 9:00 hmmm, interesting. I guess it's an IC substrate. Oh, and that electron microscope looks cool too.
Yes, though the most common shock resistant glass is borosilicate glass, which is often used for baboratory glassware just for that reason, though the original Corningware glass dishes are now made from soda lime glass, because the borosilicate glass is expensive to make, and it also has higher wear on the forming tools, as it needs a higher temperature. Cheap now means soda lime glass, though that also has had improvements to make it more shock resistant.
This film implies strongly that Corning Ware was created by an intentional process, but it's more interesting that it was a result of an accidental discovery. In 1953 S. Donald Stookey of the Corning Research and Development Division discovered Pyroceram, a white glass-ceramic material capable of withstanding a thermal shock of up to 450 K (840 °F), by accident. He was working with photosensitive glass and placed a piece into a furnace planning on heating it to 600 degrees Fahrenheit. When he checked on his sample, the furnace was at 900 degrees and the glass had turned milky white. He reached into the furnace with tongs to discard the sample, and it slipped and hit the floor without shattering.[1] Pyroceram was originally used in the ballistic missile program as a heat-resistant material for nose cones. (Wikipedia - Corning Ware)
Same with many other things. Superglue was an accident to make an improved acrylic sheet, PTFE was as a result of having a steel pressure vessel get too hot during use, and post it notes were a result of trying to make a super strong adhesive. Saccharin was discovered because a chemist did not wash his hands after work, and sat down to eat dinner. Same for sucralose. Just a few examples of something going not to plan, but having a totally unexpected result to the desired one, which eventually became the desired item over the original application, or a chance discovery combined with human error.
Didn't some of the early Corningware randomly shatter? In high school I saw a demo of photochromic glass ( darkens in daylight)..I think Corning made it. Another cool old film given new life...
At 3 minutes and 50 seconds. It seems to me that they have the compressive forces and tensile forces reversed. If one side expands, shouldn’t it be experiencing tension because it is lengthening? And the opposite side should be experiencing compression. So the right side as seen in this video should be opening up because it is expanding under heat, and the left side should be compressing. If something is expanding, it is under tension not compression.
Pyrex owes me a floor that they ruined when they decided to make cookware out of soda lime instead of borosilicate which their name is forever associated with. If it says Pyrex don't trust it to be shock stable! They lie
Thanks Fran although I nearly lost consciousness from the bland style of presentation that was used back then. I spent a good few years in materials mind you and found that an interesting subject could be made almost life threatening by those who thought a sober and serious tone was what was needed to convey knowledge.
Thanks
🥰
Thanks!
Great job on the colour correction. Tempts me to get my several hundred reels out of storage!

Just found your channel. You rock.

Those five cheeses were gonna cause an explosion one way or another.

Corning sold off the division that made CorningWare a while back and after the sale non-pyroceramic dishes were branded with the CorningWare name.
@@rockets4kids , a truthful advertising campaign for Corning would say "this ain't your Mama's Corningware!".
@@goodun2974 Yup. They also sold off the Pyrex division, and the stuff sold as Pyrex hasn't been borosilicate glass for some time either.
Thanks for sharing.👍👍
And now I want to watch the rest of the series, LOL!
Where do you find these gems? Who cares! Keep 'em coming! Thank you Fran!

So that's why my mother's heat resisting ovenware was white. Nice colour correction of a very faded film.

Thank you, Fran.
I'm shocked! Shocked! Well.. not that shocked. :P Great little film. Very interesting.
My EE background caused me to assume this video was going to be about electrical shock, it didn't occur to think about other types of shock.
very interesting - thxu fran!
Corning also made the main mirror for the 200-inch telescope at Mt. Palomar. They used Pyrex for the mirror.
2:57 CRTs on an assembly line!
not sure if intended but the title of the movie is "A problem of Shock", I like the old movies thanks for uploading!
Thank you for colour correcting and posting this video. I have more appreciation for the technology behind my Corelle casserole dishes!
By the title, I was thinking of several things this could be about. Not one of them involved glass.
Really liked the narrator. Credits say Robin King, but can't find anything on him. He almost sounds like Leonard Nimoy at times. Thanks Fran!
thank you I miss the old tech and the know how especially analog.
Hey Fran, Fantastic work. I am just noting that the title is confusing, I think it would be more clear as : The Problem Of Thermal Shock (1970)

@@SeanBZA , Vulcanization of natural latex rubber using sulfur was also a happy accident.
I love all these old educational films. Yes, there is no more cyan to be had. Even if there were, I think all the highlights would start turning cyan.

Now "music removed due to copyright"... There were no copyrasts in the 70s?
I loved this film. Now I don't feel so strange for drinking my coffee from a borosilicate flask 😂
Safety first!
Naturally, I have to ask if you've ever brewed it in glassware, too. 😂
@@bsadewitz Oh yes, it's my classic Bunsen Brew 🤣

I live in Corning and I’ve never seen some of this stuff lol
Came for the Milgram experiment. Stayed for the glass.

I inherited mom's Pyrex baking dishes from the 40s and 50s, so they're borosilicate. They also weigh a ton and a half.
I have vintage Pyrex. It has an odd slight silvery color.
cough borosilicate cough

I actually found it interesting. 🤔
