This glass is not called plate glass, it is called float glass. Plate glass was the type of glass made by grinding the glass flat with huge stone rollers and then polishing it with more huge felt rollers. The invention of the float method by the Pilkenton Glass Co stopped plate glass manufacture.
I started working at pilkington in October of this year, it’s just crazy to think a large portion of the glass I’ve touched all growing up came from this plant that I now work at
Very interesting indeed. But I'm more interested in who makes all the complicated machinery in the factory that makes and manoeuvers all the pieces of glass? And the machines that make those machines. I cant find a video on youtube on who makes the machines just to put tops on bottles for eg?
I used to work for a glass company, we used machines similar to these. "Hegla" is the equipment we used. And "Lisec" is a common glass cutting machine. Hope that helps.
"goes through a tin bath" - and what exactly is a tin bath? molten tin that somewhere doesn't affect the glass? Is the molten glass self levelling?"the glass must have a uniform thickness" - what happens to the parts that are not? Does something happen to level it or is the whole pane scrapped?
The tin is molten, in other words liquid. So yes, as is with any liquid, it is self leveling as is the glass in that state. It is denser than the molten glass so the glass floats on top of the tin. That is why this is called "float" glass. The pool or ribbon of glass is controlled by several "top roll" machines 5:04 that stretch it to the thickness needed. But yes if, the thickness is incorrect it is sent back into the system for recycling. The tin does not affect the glass in anyway you can see but the "tin side" is a bit chemically different and would not be used for any special coatings like LoE etc.
Woah I wonder why the glass doesn't shatter into a million different pieces when scored. I'm guessing it's just because it's still really hot when they score it?
If they want to tell us how glass is made, they shouldn't be telling us how one factory does it, they should be telling us how all factories do it. "To make glass, they add recycled glass..." That's like needing chocolate to make chocolate. How far back in history do we have to go before we realise glass wasn't naturally occurring, and it can't multiply on its own? Recycled materials are not a necessary ingredient, so they should skip over that and pretend they're starting from scratch, so we can all learn something useful.
True, but it is an evolutionary process. If my glass plant similar to this, for instance skipped the cullet (broken glass) just for educational purposes, it would change the batch and all the heat settings. Which may not sound like much but is a big deal. In reality the process is identical without the recycled glass other than the temperature to melt the batch will be much higher and less cost efficient. We use 20-27% recycled glass in our process depending on what is available. Only like glass (same recipe) will be used. You don't use Smuckers jars in window glass etc.
Masha Allah

i was hoping this video was of actual plate glass
@@SuperAWaC oof
Absolutely correct . I am amazed at how many people from manufacturers to architects refer to float glass as plate glass .

Amazing industrial marvel
Interesting video
I read that this factory was down for maintenance a few years ago. The factory had run continuously for 8 years.
Factory in naplate(ottawa) only went down because it got hit by a tornado
A dumpster full of broken glass shards sounds like a perfect final destination prop
So do industrial machines flinging around giant sheets of glass. :)
4:20 And here we see the first human fingerprints being added to the glass. ;)
I didn't know Ross from friends got a new job as a narrator 😂
😂😂😂
Glass can be used to make photo frames and other items like mirrors.
Citation needed.
Narrator sounds quite a bit like Ross from friends.
very informative

Now to start the never ending journey of watching How its made videos.
Are u still watching them 8 years later
What is this song called? Its beautiful
Unfortunately It doesn’t have a name, as it was composed specifically for How It’s Made.
classic old episode of How It's made
thats cool, but whats that song?

water hot n cold crystallize adhesives from glass
i thought you just put sand in a furnace
Minecraft logic haha
huge factories with machinery too big to move... idk I geek out on this shit lol.
It's like willy wonka, but they are making money, not candy ;D
Why is Capt. Sobel narrating How it's Made?
"first step to make glass is take glass and crush it and add it in" ohh i seee. i need to magically conjure glass to make glass.
Wonder what would happen if you let a raging bull loose in that place..
He'd probably get mobbed by employees wanting autographs. Not every day you see Robert DeNiro in a glass factory!
Happy 😢🎉🎉🎉😢
Ok now the plumbus please
THAT'S who they replaced the old narrator with?????
Microsoft called, they want their windows back
+TheAngryGrandpaShow lol
cool how automated this can be
The quality of video is 480p. It`s very bad...
Cos it was filmed in the late 90s
very

and now search for: how it's made mirrors
Blurry video
