Why are there Black Dots on your Windshield?

- You’ve probably noticed these little black dots all around your windshield.
Without them, glass windshields would be a lot weaker.
They’ve actually been around for a few decades, after car manufacturers started to use adhesive to hold the windows in place.
But have you ever wondered what they’re here for?

That was actually informative! And not lengthened to oblivion!
I honestly thought the black dots amplified electrical signals to your phone xD
@@ParleLeVu LOL, I heard that too, in a garage 🙂
@@ParleLeVu Except they have existed long before cellphones....
@@kylem1112 I was saying I was erroneously thinking it was for signal, so why are you correcting me?
@@ParleLeVu I thought it was to help the car confuse predators
What a great video. No unnecessary history lesson, no padded run time.
Just loud, unnecessary music…
@@topcat5988 Yes, unfortunately that was there.
@@topcat5988I barely heard any music.
@@enginepy My guess is they re-uploaded with the music track lower than the dialogue.
Some very interesting worthless knowledge!
I loved it!
Why do you play background music louder than the narrator's voice? It makes it difficult to understand what he is saying.
Corporate people following the same format as other corporate people without thinking about it.
In the age of the internet, we now know that background music like this isn't good at all in a video that's meant to inform. But unfortunately the corperate world is still stuck with the old ways with jingles and infomercials ect.
This is probably your speakers. I read your comment before watching the video, and I thought I watched the wrong video. Easy to hear.
@@MasterArkannor While I don't have the ultimate audiophile setup I have decent stereo speakers with separate tweeters and woofers. Regardless, the video should be produced in such a way to still be understandable when played in less than optimal conditions.
@@GoatTheGoat Your speakers are definitely better quality than my phone.
Its not louder than his voice, you have something wrong with your audio equipment
Love how you keep it concise and focused. No fill. Turn down the music a little and this is perfect. The standard youtuber would have spent 18 minutes conveying half the info...
The history of glass from ancient antiquity to modern times. lol
"For centuries, people have been making glass. During that time, they've not only been making glass, but also using it. It's been used for all sorts of things in the past, right up to the present and probably even into the future.
But what _is_ glass? Glass is a hard stuff that you can see through. Except for the sort you can't see through..."
Need that youtube moneh
And then he'd ask you watch his next video so you can get the rest of the information.
Technology connections however would somehow have simultaneously increased the length of the video to 30 minutes while somehow managing to remain entertaining throughout, as well as increasing the amount of information to an absurd level.
So refreshing to see 1 minute of valuable content instead of stretching it to 2 hours with bloat. Please keep it up!
Man I love the Internet
Yeah, it's great. I guess I will make a 2.5h video essay about this very video.
Valuable content? This video is literally pointless.
@@Steven-ze2zk Guess you are the kind of guy that prefers a 3 hour video on Kim Kardashian's preferred bedroom decor. Go waste your time there while the rest of us learn something.
@@tatotick8513 What have you learned? All I learned was how boring this video is. Oh, those dots regulate temperature and hide where they glued the window on the car. Wow, fascinating stuff! 🙄
I'm so happy how easy you people are to impress. It keeps my dreams of being a successful CZcamsr very much alive.
It is insane that a brand new channel about a dry subject, would so perfectly nail timing, key points, visual interest etc. amazing. Really great video
And let me add thumbnail image! Just all around perfect
@@ScorpioIsland We've gone full circle. Corporate CZcams was always low effort cringe, now all the 'content creators' have become stale and we're back here again.
@scorch527 "circle of life" has so many applications...great observation mate
It’s a bot channel
Great stuff man, for future vids please turns down the background music
I have worked on windshields / windscreens for 10 years and yes I can confirm all this to be true and accurate. It's also to hide the urethane bead underneath and the gap between the plastic pillers that run up each side of the window and the metal that the glass is bonded to. Trust me won't be pretty if you could see all the stuff underneath. Good job I'm impressed.
I am surprised that your are impressed by a well explained video from a channel dedicated to adhesives and such
@@Pinhead101 you figure but trust me when I say people have no idea. Most mechanics don't work on Windows to cars. I get a lot of back in my day we used to use a rope to install glass. Yah like all of 3 semi trucks still do that today and is mostly on cars from the 90s back. So they think they know windshields but in the past 30 years they haven't installed something it does change just a little bit. I see many mechanics make mistakes about windows on cars and some people on CZcams not explaining things correctly. Just glad to see someone say things correctly in this industry for once because it normally never happens. Not even dealerships work on car windows. They use a different company to come out and replace the windshields. Dealerships don't even make glass. Like Ford and jeep and BMW. They have a different company make it and brand it with there mark. Normally FUYAO or Pilkington.
I wish all windshields weren't laminated and designed to shatter into small pieces, it would be funny if all windshields are still non-safety glass.
@@automation7295 Fun to see blow up but not when driving. Widows have two layers of glass to them with a layer of PVB in-between them. This layer is vary difficult to rip apart. It designed to keep a person from being vary stupid and not go threw the window in the event of a crash and there not WEARING THERE SEAT BELT. Also in the event of a rollover the window disperses the wight of the car and prevented the roof from caveing in, even when the window is damaged. You also don't want 1000s of glass shards coming your way in the moment of a crash and raining on you. It is hard to rip the PVB apart but not puncture it. It's like a net of sorts. Door glass and back glasses do not have this on most cars from the 80 to mid 2010s. Manufactures found out the lighter the car the better the mileage. So one of the first things they did is make door and back glasses tempered (one piece of glass) rather than laminated to save weight. Soon thought all door and back glasses will be reverting to laminated glass again for safety. Has it's ups and downs. Makes break ins harder. Get stuck in a crash you can just pop the window with a window Popper but with laminate door glasses you'll have to rip and tear until it is done.
@@Pinhead101 I'm surprised that you are so naive as to trust the labels on a video. A channel name does not guarantee the quality or accuracy of the content. There is a massive amount of clickbait on CZcams and across the Internet that attempt to fly all the right flags of legitimacy and interest. They lure in viewers, only to string the audience along with 20 minutes going nowhere and revealing little information that is accurate or new.
From a glance at a headline, a thumbnail, and a channel name, it can be difficult to gauge whether clicking on a video is going to be worthwhile, or a waste of time. Most offerings are a waste of time. It is quite refreshing and impressive to see quality, concise, interesting content as advertised. And it's worth saying so.
Why would you criticize someone for complimenting someone else on a well done piece of work? What does that do for you? Do you think the world would be a better place if good efforts were not acknowledged or praised? I mean, that's not the purpose of trying hard. But maybe you could explain the purpose of your criticism.
And I always assumed it was just some kind of sun-blocker at the edges to aid the driver. So it is a sun blocker, but not just for our eyes.
Not for your eyes at all.
Just to protect the adhesive from UV.
I think it's both. The soft edges are probably less distracting to the driver.
It's amazing how much engineering turns out to be behind something so seemingly innocuous. Great video.
This was fantastic. Very clearly explained, concise, yet answered a question many of us have. Also no clickbait or trickery. Perfect!
Straightforward title, no stupid face on the thumbnail, no filler. I wish more videos were like this.
Always love it when one of my childhood questions can be answered in only a minute and a half.
When I was a kid, I liked to imagine that those dots looked like a crowd of people in an audience.
I totatally see what you mean after your comment. LOL!
You had a wonderful dense of imagination! @@manlystan100
When I was a kid they never had this. Mostly just a rubber with sometimes a chrome insert.
Now I feel old! lol!
Direct and to the point. No fluff. Great video.
One thing to point out about the frit behind the rear view mirror, is that the rest of the glass has UV (and presumably IR) filters which can prevent the signal of certain electronic tags (in particular the old "Fast Tag" system used in the Mersey Tunnel). The frit behind the rear view mirror has none of the filter there, so mounting the fast tag (or similar) behind the mirror enables the some of the signal to pass through the glass, whilst still giving the driver some eye protection in that "fritted" area.
The precious and precise piece of information which i was going to post myself unless i had read it from your comment. Thank you Buddy! Well formulated!
That's the kind of less known facts I love learning about. Thanks !
There is also a camera behind the Frit in Rear view mirror mount..
The glass itself restricts UV at the higher frequencies, e.g. I wear photochromic grey spectacles, which lighten up inside the car. Some car models, notably certain Fords, have electric heating elements built in to the windscreen, which does inhibit signals, such as those used by cameras that want GPS reception for navigation.
@@johnkeepin7527 you sent me on a journey to finally wonder why so few cars even of high make have a heated windshield when it's almost universal on the rear. Apparently it's a ford patent...
well that was 90 seconds well spent. Thank you!
Short and to the point, thanks for the video!
One of the most useful one minute i have spent on youtube.
straight to the Point with all the Information provided without running 10 times around the Bush...... *definitely a Thumb Up*
it's 7:30 in the morning, I have not slept yet. but I now know what those dots on windshields do...
LOL
Now you have found peace of mind I hope you are able to sleep. 😊
@kimvibk9242 lol! I actually did sleep quite well. Thank you
Sleep's fer dreamers, kid.
Very informative. I love videos like this about things that I’ve always wondered about but never investigated. Thanks for posting.
Yet another one of those things I have seen for years, often wondered what it was for, then when I find out I am like "OF COURSE...that makes so much sense"
Stuff like this is why people being experts at things is important...things like this exist in every single aspect of humanity's knowledge and only by specializing can we have them in society.
Also totally watching the other stuff on this channel now
That was interesting, thank you
I really appreciate how you're not here to waste my time
WOW! The most amount of useful information in the shortest amount of time I have ever seen! Being a nerd and a geek this is the closest thing to mainlining as it gets. Keep up the good work
How did you make a minute and a half video about a subject without stretching it out to include the history of glass, cars, windshields, and the sun before getting to the point? 🤣 Thank you!
An informative video in 90 seconds? This must be heaven.
A short video, but very effective- I have learned something new.
This is one of those things I wondered about every time I cleaned my windshield but forget about almost immediately after. Baring Alzheimer’s I don’t think I’ll be forgetting its purpose.
P.S. Drop the music volume a couple of points so that it isn’t competing with the narration.
I have an 80s car from sunny southern California that had no 'frit' and the urethane seal completely separated from the glass to the point where I was able to lean the top of the windshield out of the car from inside. Where it was protected by the cowl panel, the urethane was still adhered, which to me proves that the failure was directly related to UV exposure.
When I had the windshield replaced and re-glued the new ones they make still don't have frit! So I guess in 30 years I will need to have it re-sealed again. haha
FWIW there are UV-resistant glass compatible paints, even without the benefits of proper bonded frit it might be a good idea to try and protect the adhesive that way.
Got this video recommended to me not long ago! I work in this industry and it was very interesting to learn about the heat distribution. We work with all kinds of glass frits, but I never knew that. Great video!
Thanks for the information and for not making this a 20 minute video.
Years ago there would be intentional flaws in the "dot matrix" pattern near the tip of a wiper blade. This gave a target for wiper alignment for assembly and for service. The wiper arm base had a smooth no thread zinc insert that was softer than steel and when you tighten down the nut, the wiper arm pivot would cut grooves into arm bushing.
Precise and Concise. Kudos to the video creator.
We knew if we watched enough of these information videos, one would eventually come along and nail the topic. Very rare indeed.
Short and to the point. Without yelling with fake excitement like other CZcamsrs. Perfect 👍 thank you
what an excellent advertisement for your own content. A simple question, a very quick answer, a recommendation to go to if you want more details. I'm not interested in more information than what I got from this video but I'm interested in seeing more from the channel. 10/10 would watch short video answering question-I-never-think-to-ask again.
Interesting video, subscribed to watch more, thank you; hope you have a successful new year 🤞
Very nicely done. Kindly instruct your editor to normalize audio levels for this platform. 😊
There is an entire channel about glue??? Amazing!
This was cool! Thank you for not making it a five hour video essay with unfunny bits disrupting the flow, plastering your face all over your thumbnails and videos, and making it actually pleasant to watch.
Great details and straight to the point.
As a window tinted of 40 years I can tell you that those dots are a royal pain in the A-S !!!!!!!!
As someone who painted windshields for many years. Making sure all the dots were there was a royal pain in the A-S!
I’m excited because I woke up this morning thinking I wasn’t going to learn anything today.
Finally a question that's answered without padding the video length to an extreme extent. unlike a certain other channel
Something about finally getting the answer to this question feels like scratching a decades old itch. Like, I wondered this question ALL the time as a kid riding to school in my mom's car and it feels SO immensely satisfying to finally have an answer
My first car still didn't have electronic fuel injection, it was from the old era of carburated engines. An old car from the 80's when car windshields were not glued to the frame with this new procedure, which seems to have become widespread in the industry in the 90's.
Passenger airbags won't work properly without a stronger windshield bond, because they fire up towards the windshield.
@buddyclem7328 , interesting, didn't know it, thanks for the information.
Gives the information it announced to give and didn't wast my time - a "like" was inevitable. Please continue with this concept.
Just the fact of how concise this was made make it so much more valuable
Yes, 100% informative and to the point. Very good, thanks!
Great wee video.
Thank you for actually answering the question in a consise matter and not stretching this video to 15 min. and open it with talking about 'the history of windows' like so many bottom feeders.
Cheers.
Amazing. I've always wondered. But more crazy is there are people who figured that shit out. Kudo's to them and real science.
Fact-Window weld adhesive is strong enough to hold roof panels on vehicles. I've seen body shops do it and never bother with spot welds.
I figured that it is it just to hard to clean a windshield all the way to very most outer edge. The old saying, "I don't do windows" was because unless you clean very completely you get smeared haze and streaks.
It's already been said a few times, but beautifully short and to the point. Excellent work with superior quality 👍
Yesterday while playing Cyberpunk I wondered what these black dots are. Today CZcams presents me with this video. The algorithm knows.
I always thought they were there to hide the bonding underneath the glass, as opposed to the old way screens were held in where rubber was used.
They do actually say that if you watch the video
Very exciting stuff..I’ll watch the next video with the wife & friends I’ll get them round & have the popcorn machine ready.
I've noticed it there since I was a kid, but never questioned why it was there. Very informative
The ceramic frit only has ONE layer, usually on the inside of the glass, but in some circumstances in between the lamination (Pilkington). Otherwise this is accurate.
Pilky01
Interesting. I noticed that my van's front windshield that was replaced several years ago doesn't have those black dots. It developed a crack on the lower left corner. I don't think anything hit it because I don't see a point of impact anywhere and the van is parked outside.
Worked in an auto glass factory for 20 years. Even some OEM windshields don't have those black dots. More likely a defect at the time it was made. Possible defects are too many to mention, but I don't think it was the lack of dots.
Taught us the thing in a few minutes. 10/10. Perfect video!
Thank you for making a youtube video with a question as a title that is answered quickly. Informative and concise is nice.
And there was me thinking it was just to artistically hide the glue that stuck the windscreen in place, ever since they did away with rubber seals. I would love to know where they came up with the word 'FRIT' from though. Great video.
Let me Google that for you since you were too lazy to do it yourself.
"According to the OED, the origin of the word "frit" dates back to 1662 and is "a calcinated mixture of sand and fluxes ready to be melted in a crucible to make glass". Nowadays, the unheated raw materials of glass making are more commonly called "glass batch".
In antiquity, frit could be crushed to make pigments or shaped to create objects. It may also have served as an intermediate material in the manufacture of raw glass."
en.m.wikipedia.org/wiki/Frit
Thank you for being so informative about this medieval industrial term. I never thought to Google it having assumed "frit" was a recently invented 'F'-word that did not pre-date the practice of putting spots around the edges of car windows. @@x808drifter
wow, @@x808drifterthanks for insulting people while not explaining why it's called a frit.
@@x808drifter and you were too lazy to read the text that you mindlessly copy and pasted into your comment. hypocrite.
How about windshields with weird wires that run along them 🙃
Antennas on some older cars, and defroster on some
Those are heating elements
Ha you talking about my old Toyota 😂
Great video with no dumb stock footage. Thanks!
Ohh dear, i tried to find this out for such a long time now but never knew what to search for exactly. Now the youtube algorithm did its job.
Thx for the great video.
Wonder how many windows used to fall out before the frit🙄
Windscreens weren't bonded before frits.
He literally explained why its an improvement, why are you being salty 😂
@@shocktncHe also explained wrong.
So their saltyness is well placed.
When they went from old style rubber seals to the bonded windows this was always a thing.
it is present on ~
I often wondered what the little dots were. Thanks for posting this.
Things I didn't know I wanted to know. Thanks for keeping it concise and informative.
Stop with the music!
It’s your speakers. I could hear him perfectly fine.
At least he got right to the point, I appreciate that…
You get a comment of appreciation for not padding out that explanation. Well done!
Short, informative and to the point. Love to see it.
I love watching little informative vids like this while sipping my morning coffee.
Never knew I needed a channel teaching me the ins and outs of adhesives but here we are
I thought those dots were part of my tint. You learn something new everyday
Really nicely explained, and the animations were helpful for understanding. Thank you!
Now THAT is a brain itch I have had for decades. Now I know. Much appreciated content.
Damn thats a good video! Simple, precise and highly informative on a very easily identifiable everyday wondering.
Good job!
Another great video! Whenever the topic of our favorite CZcams channel's comes up I always make sure to mention Industrial Adhesives Learning Centre
Concise videos like this really...
stick with you
Thank you for a short and concise explanation, I've always wondered what they were for, now I know!
This video just got straight to the point, and explained things quickly and clearly. +1
Thanks, this was actually useful in that it clearly explained that the dots have a function beyond cosmetic. Much appreciated!
Absolutely perfect! Explained everything and not too long! Thanks!
This video was actually great at explaining it well in a short time!
Best video I've seen all day. Very informative and interesting.
Great video, love the information, and that the video hasn't been padded out to a few seconds over 10minutes just for youtube ads!
I have learned something new today. Thank you.
Thanks for posting such an informative video.
I was just wondering about those dots just the other day! Thank for the info!👍
1:30 seconds of what i was actually looking for, FINALLY GOOD QUALITY! here be rewarded by the algorythm
This video could have been 20 minutes long, 15 of which would have been beating around the bush in an overenthused voice and 4 would be spent on a genuinely fascinating history lesson cut short for no reason.
Instead, this was a minute long and answered the important questions with clear visuals. Thank you!
So nice that some can still make short videos without actually exluding any of the information
This is one of those small things in the world that I have never really thought about, but is still something that I definitely would end up googling at some point if I really started thinking about it 👍🏿
As it happens I had wondered. Thanks, great vid. All the info and you assumed we'd understand it without repeating it over and over.
Straight to the point. Bravo.
Oh my gosh thank you for not burying the point in 30 minutes of preamble
I also do support such informative yet lean videos! Thank you!
