🤣🤣🤣
Fucking frfr...
😂 seriously
Lol, I was coming on here just to say that.
😅😅😅 this is great I hate all this talking
99% of drivers don't know what they are for, because only 1% of people have the patience to watch the whole thing til the end before moving on.
And then that 1% still don't know since the video gives the wrong answer.
😂😂
Imagine having an attention span longer than 5 seconds in 2024
u dont know too
I knew right away. It's also on our oven and microwave.
That black dot is called a frit. It's actually a ceramic enamel band that's baked into the edges of the windshield during manufacturing. It helps to seal the edges of the glass and provides a smooth transition from the glass to the adhesive used to bond the windshield to the car's frame. Additionally, it helps to reduce UV radiation inside the vehicle and prevents the adhesive from deteriorating due to sunlight exposure.
So not what this video says about dissipating heat so it doesn’t crack ?
@@nunocolon That as well.
Interesting. Thanks for the comment 👍
Turned him saying "Black dots" into a drinking game and now I'm dead.
They are called ceramic frit, it stops uv light from affecting the urethane bond between the windshield and the pinchweld.
I like how that sounds better.
Thanks a bunch!! 👍🏽 I'm educated now! 👩🏽🎓 😄😄😄 😆😆😆 "Ceramic Frit." 🤔
I've seen it on the windshields and examined it occasionally, and I never knew what it was for. 🤔🤔🤔
I've been LICENSED to drive since 1990; I began "PRACTICING" driving when I was 12 years old in 1972... supervised by my Dad, of course! 👨🏻 ❤
😬😬😬 😏😏😏
Thank you, I was JUST about to write that out... this video is complete garbage. Definitely there for the urethane.
TY
Yep, I've used it on many yacht windshields.
Its called the "frit" and it protects the urethane from UV breakdown. I've been an autoglass tech and auto glass small business owner for 27 years .
🫡
Me too but for 323 years now.... I'm about to retire in 2 years at 325 years going!! Its been fun... time to travel the world for the next 500 years or so!!
@simonbenn5340 are you mad I built a future for myself? What a odd post to bash on someone. Let me guess single mother, part time jobs your whole life ? Can't stand to see hard work and success , wants the govt to hand you a check ? Moms basement as an adult? All u need now is some trigger words to complete your snowflake journey
@simonbenn5340 are you upset I know the industry? Show us on the doll where your single mom hurt you . Don't be mad pops was upset at how you turned out .
And? Do you want a medal or something. Boring job how the hell do you do it.
I've never heard of a windshield spontaneously shattering prior to the invention of these dots.
Neither have I.
My uncle's 1940s car had one bust while in the hot sun. It did happen.
Why no black dots on house windows
Well, that's 20 seconds I'll never get back
If you eat healthy food and do exercise everyday those seconds won't matter....😅😅😅😅😅
If you let go of your life and give it to Jesus - you can get your life back forever
If you don’t, you won’t &’Hell is default
Never getting those seconds of my life back.
it wasn't being used effectively anyways :)
@@pc-ft9dy lol true
Losing the same number of seconds from my lifespan in solidarity with you 💪
i mean its useless anyway so who cares
what about the second you lost to leave a comment oxygen thief?
As a kid in the 80's I was sat in the back seat of my parents' Ford Taunus on a quiet and nice sunny day while we were taking a drive. Suddenly the rear window exploded all on it's own, glass all over the back seat, so I for one certainly appreciate and understand the reason for this improvement.
I don't think I've heard of a Taunus, what's under the hood?
A engine
@@GODh8sfag5 It was a 1.6L four cylinder engine. Pretty normal engine for a car in Europe in the 80's.
The spontaneous breakage like you saw is usually due to a defect or inclusion of a small particle called nickel sulfide that expands over time and can break tempered glass.
B.S.
Those dots are sometimes nightmare for us who are tinting windows.
Made windshields for years. We called it “fade out dots”. As it was the paint band fading out. As I understood, frit was a glass ingredient adding to the paint to promote permanent adhesion to the glass when fired in the furnaces.
100% of drivers don't give a fuck
Exactly 😂. Actually he didn't say most of the back edge is for primer glue. Black paint Stick to the glue/primer and the to the car frame 🤦
...and the other 10%...(oh, wait)
Facts! 😂😅
Not that you would give a fuck, but that's 100% wrong.
I drive and I do give a fuck, so it's certainly not 100% not giving a fuck. Man that's alot of fuck btw.
I have always wondered it so you're wrong
Those dots are called a “dot matrix” it is a part of the “frit band” that runs the outside of the glass. In most cases it helps primer less urethane adhere to the glass and body while simultaneously keeping UV rays off of the dried urethane to help preventing dry rotting and the urethane cracking.
You must be a window tint installer. That’s for info
@@DavidSanchez-wm8wd close. Automotive glazier.
Also helps hide the pig snot, glue.
Check out the dots on a Harley Davidson truck.
Sekurit Saint-Gobain is credited with inventing the black dots around the glass on a car, known as frits. These black enamel dots are applied to the edges of automotive glass during the manufacturing process. The purpose of frits is both functional and aesthetic.
none of the cars in the 1960's or 70's had these and I don't remember any cracking glass due to heat.
I think because back in those days there was no rapid environmental destruction which could lead to high temperatures but these days environmental destruction is excess
@@sgwlw7777yeah those days in summer time also my mom told me they use to wear sweater cause it cold.
@@sgwlw7777 are you serious lol
@@kevingilmore9366 yes
@@altolyngkhoi4239 We used to place our popsicles into the freezer to thaw them out some. We were so relieved when winter came and it warmed up a bit. I really miss those days before the environmental destruction.
The special glue used to fix the glass is sensitive to sunlight, long exposure makes it brittle, so the dots help with keeping some of the sun away while blocking less of the view than a solid black stripe. You learn this detail while getting certified by SIKA, one of the makers of this kind of glue.
Thank you
This is the reason. The guy who made a whole video about it, didn't even manage To give a reason on why those dots are even there.
I came here to say the same thing, lol
Thanks for the info. I thought they were an antenna. ❤
thank you for explaining why because this video absolutely did not!
For anyone wondering those dots are called the frit and it also makes it so you dont see the glue under the windshield. A crack going across your wi dshield does not put your life in danger. The windshield is 3 layers, a layers of glass on the outside with lamination between each piece of glass. The windshield is designed to not break into shards and hold together. We have vehicles come in for a windshield replacment hitting deer and turkey with the windshield completly caved in and the worse youll get is some small glass shards and dust in your vehicle which yes does suckand yes you will might have some cuts but your not gonna be impailed by a shard of glass. Some door glasses are also laminated glass but most are tempered and break into small chunks not huge pieces that can cut you in half.
The black coating was invented in the lab I work at. It was developed at Johnson Matthey and it helps the glue holding the glass to the car under the black coating to not be destroyed by UV light. Also hides the silver used for the heating element in the back windscreen.
They use the black enamel outside the windshield to block the sun's ultraviolet rays from melting the adhesive underneath the band. This keeps the windows firmly glued in their place. The black dots, or “dot matrix” actually help distribute temperature evenly to lessen optical distortion or “lensing”.
Mr Google
Spot on. The sun will deterioate the urethane.
Thank you
it's a "frit" I was amazed that this robot spouted this bullshit
Thanks. You should've narrated this short.
For one the windshield is laminated and not tempered. That black band around the windshield is called a "FRIT BAND" It hides the glue used to install the glass. Laminated glass does not explode it just cracks. You would have to really smash up laminated glass before it is a danger.
This video is total BS.
Every winter for nearly 25 years, my dad would go out every morning there was ice or snow on his windshield with a pot of boiling water and pour it to defrost his wind shield with no problems whatsoever. On two sperate occasions I've poured a cup of hot water on two different windshields to help me break up the ice so I could use a scrapper to get the rest off, ending with both of them cracking. This only tells me the manufactures are making the windshields weaker and weaker over time.
A dealership will tell you its a antenna 😂
That’s exactly what I thought it was. 😂
They would be wrong.
Now you are almost correct usually the antenna is part of the rear glass. I have seen one windshield that had one once. I forget what vehicle it was. Many rear glass antennas look like they are part of the defroster and are usually right above the defroster. If the vehicle had that setup.
@@spagsketti I just said it's what a dealership will tell you bud
I always thought it was part of the windshield heater element
Glass is glued in with urethane and is sensitive to ultra violet light and becomes rigid and then thermal expansion is an issue.
U can apply the technology to the actual frame of the car as well as the frame of electronics to prevent overheating even the separate parts of the car to prevent overheating in the engine
Its designed to assist the adhesion in creating a tight bond and eliminating any slipping when placed in position and during reinstalling the trim/moulding .
The black stripes and spots are called the frit. During installation, the frit is a bonding point between the glass itself and the frame of a car. The frit is baked into the edges of the windshield glass so the glass bonds to the frame. The windshield component also hides the adhesive to provide a polished appearance.
While the side of the frit that is facing inwards bonds the glass and the frame, the side that is facing outwards has a different purpose. The side that is facing outwards keeps the UV radiation from damaging the adhesive. Long-term exposure to direct sunlight that is damaging to the adhesion in the glass. UV radiation can damage or weaken the adhesion over time.
I believe the dot(singular) is called a "frit". The plural version is, "frits".
@@budlanctot3060 yes - getting more detailed/specific... the dots are the frits and the black band is the frit. But both together, is more generally known as just the frit.
What is the deal with this voice on every freakin video?
Artificial intelligence voice
@steelisthemeal thank you captain obvious. Why does it need to be on every freakin video? There are thousands of AI voices that can be created. This one is so annoying and on everything.
@@jeffs6090 I'm with you on that. It must be the first choice on the voices list or something and they pronounce all kinds of sh.t wrong too.
@@stevie.dx1710 It sounds like AI Ice T
still better than TikTok voice
The glass cracks when it absorbs heat, but it doesn't crack when the black dots absorb even MORE heat. Makes perfect sense.....
60 yrs of owning a car, I've never had this issue and never heard anyone else have it either.
Thanks for the info 👍🏽👍🏽
BULLSHIT. I HAVE HAD 3 TRUCKS WITH THESE DAMN DOTS. ALL 3 HAVE CRACKED DURING THE SUMMER.
It'd be way worse if they weren't there. I remember back in the day when they hadn't figured that out yet and no cars had them. Nearly every car on the road that wasn't kept in the garage had stress cracks in the back glass or windshield within a year or two from new. Best way to stop it is to keep it out of full sun in the sunmer.
I would bet there was a rock chip in the glass that caused it to crack. A rock chip on the edge or close too it will crack faster than one in center of the windshield. There is a lot of pressure on the edge when the glue cures out.
I heard that rumour too, about 99% of drivers not knowing what those dots are for.
Explanation: The Black dots relieve the glass from heat through dissipation.
Thank you
What about the side windows?😅
They're not slanted like the front and most back windows which are more directly hit by the sun for longer periods of the day. Think a little. It's easy.
absolute Bollox So why does the door window not shatter
It is tempered and windshields are laminated.
Windshields are "glued" on to the car body. This fretting protects the "glue" from the suns heat while avoiding an abrupt temperature difference on the glass...
Hats off when the comments are more beneficial than the video itself.
Well I am an auto Glass technician
Well how about the clear glass who doesn’t have a black shade around the windshield?
I think it’s just cosmetic instead of looking at the urethane ( you guys call it clue ) they put it out there to hide it
Well I could be wrong
I have a question for you, on my toyota windshield there are some small sort of code printed randomly on the glass, any idea the purpose?
@@sanookaus1334 it’s a print of the manufacture who made the glass if it’s never been replaced you will see the same print on each door window
@@samirhadjou8163 One more Question if you don’t mind, why are the side mirrors reflection not true to size, as everything looks far away. Cheers.
I am surprised U don't know it's for the HVAC System
@@StationRussification how about the clear glass
Another indian bot channel 😂
Its called a dot matrix and it has about a dozen uses. The only one we get is it reduces sunlight on the edges of the window. Some windows have a 4 inch strip of them across the top.
I'll say it for everyone :
"You are not entitled to my attention."
Who else watching this while driving and looked over at your windshield?
David Cruz
I had a windshield replaced a bunch of years ago and the guy told me this info. Pretty cool.
At some point I was just watching this short, not to find out the answer, but to see how long it would take him to get to it
Little known fact is when you tint glass the thicker and darker tint adheres to these dots better
It’s called a shade band or visor frit . Did claims for Safelite for a time 😊
I got those black dots and a crack going from one side of my windshield to the next.
Back to the drawing board for him.
Wow! I always thought it was an embedded AM/FM antenna.
To keep the glass from shattering when it's hot. You're welcome. Now you don't need to sit through it.
Good job you make a minute feel like an hour with your overly complicated explanation of something so simple 👍
That's cool 😎👍
Ive been carrying that silver car shield so the car wont get hot & ruin the dashboard & the wiring inside the dash!!
I always thought it was to weaken ice at the edge of the glass to make it easier to clean off
"Don't ever, for any reason, do anything to anyone for any reason ever, no matter what, no matter where, or who, or who you are with, or where you are going, or where you've been... ever, for any reason whatsoever..." - Michael Scott
Windshield is what we call a safety glass …… it doesn’t shatter like the windows because there’s a film in it that doesn’t allow the shatter . Tempered glass will be the one u gotta worry about but it doesn’t have that either however u can tint them .
It's called a dot matrix used for the robots to line the 2 sheets of glass together, and to keep uv light form destroying the glue.
Michael 😮
The front is not for heat. it’s to fill gap between visors sometimes, but always to not show the blackout as a smooth line on a curved surface (black out is to cover adhesive)
"Not everyone knows what they're for" > "it's rumored 99% of the drivers don't know..."
If there was a world record for the most words in a CZcams short… this channel would definitely be on it. That has to be a record 😂🫡
It's crazy bc I was just thinking about that a couple of days ago. I thought it was like built-in sunglasses. I know the visor is there but I thought that was like the first defense.
Not only are the dots at the edge of this gradient pattern bigger, but the dots at the center are smaller. Unbelievable right?!?
Bruh this is yt short, not a regular video. Straight to the point!
The dots help transfer heat and prevent cracking. That’s all he needed to say lol.
That black ring also hides all those dead bugs and spilled candies and drinks that can't be cleaned out because the glass is very close to the dash.
I literally used to design and print these on glass for military vehicles.
the dots have an exclusively aesthetic purpose because they serve not to see the glue for the glass, so they represent a transition from opaque to transparent
The more common reason is the adhesive that holds your windshield down, weakens overtime in direct sunlight. It’s more aesthetically pleasing to look at the dots then just a black border around your windshield of silicon.
I think these dots were introduced to hide distortion which typically occure next to the frame.
I always thought it was for safety so the glass wouldn’t shatter never thought about thermal heat. That’s awesome
"Hey, those little black dots on the windshield? They're for heat dispersion in the glass". 10 secs.
This was inspired by the natural heat dissipation effect of stripes on zebras.
Just recently I asked my Mother, "Hey Ma, do you remember when the car's front windshield had about 4-to-5 inches of blue or green tint?"
Me sitting in my car on break gaining more knowledge! 😮
There goes 30 seconds of my life I'm never gonna get back.
this short should be 15 seconds long max.
Holy shit I had to wait till the end of the video to figure out what they were.
Wait till he find out about the lines on the rear view window 😂😂
I’ve never felt so impatient watching anything ever
Rear windscreen blew up on me once. Peugeot didn’t allow for expansion/contraction in the 106 model. Ice then warmth. Pop. Not cool. Massive bang. Thought someone threw a brick in the window. It was a courtesy car!
Man the anticipation gave me rly bad anxiety..
How to tell someone something without actually telling them:
Could this be used on our home windows?
I'm checking at the bus glass next to me 😅😅
I remember back in 70s windshields eplode evrytime you parked in the sun.
The struggle was real!!!!
Took this guy forever to get to the explanation
The color black and the Sun have a very special relationship. The same with a certain group of people 😊
Relieving the stress of thermal expansion.
I have walked outside to my car living in south Florida during summer and found a shattered window ..the heat here is out of control ..you have to leave your windows open a lil bit
I thought it was sensor’s for the whippers to turn on automatically when it’s raining 😂
This long explanation of a video reminds me of a, Google recommended, People magazine article, I read a few minutes ago about “Jewel (singer/songwriter) has finally found love and you won’t believe who it is”… after about 20 minutes of reading about her whole life story, multiple failed marriages , her young teenage son and every other thing imaginable, about her life and career, the very last freaking paragraph tells you what you’ve been looking for since you started reading the article. It tells you something along the lines of, “after some soul searching, she finally found out exactly who she really was” and then goes on to say, and I quote, “after all these years of searching, she has fell in love with herself”!!! I was like, “WTF??? That’s the LAST thing I ever read that People magazine has anything to do with!!!”. But I guess I should’ve expected some stupid bullshit like that from People magazine!?!?!?
It’s also designed to hold the windshield urethane on the glass
THANK YOU WHOEVER FIGURED THIS OUT
Seems this man is narrating every video on youtube.
So funny how right when he said the further from the edge the smaller the dots, as they show that there are tiny dots right next to the edge.
Now this is the content why i pay my internet bills
Whoever invented the airbag is a genius... whoever invented the seat belt is a genius.
Whoever invited those dots you can thank them for evenly heating up your car interior to 145F in the summer.
As an engineer that worked with sunroof glass assemblies and the manufacturer of these glass panels. This is utter BS. Those dots are primarily used to hide defects in the ceramic coating on the inner side of the glass. Turns out ceramic printing in a straight line is a lot harder and more costly than dots due to the increased amount of scrap.
It prevents rubber break down on uv rays.. (seal bethween glass and car frame)
