Big- O, DIY Glass cutting, glass, tempered glass, how to, how to cut glass, glass cutting, @thisisbig-o, laminated glass, cutting tempered glass, how different glass breaks, can you cut tempered glass?
Im glad you did this video .You made it plain and simple. Know I know how to tell the difference in safety glass vs plain .. i never knew that aspect on identifying the differences. I do know tempered glass does not like to be cut and has an explosive attitude when broken . thanks alot guy!
At last, at last, a video that shows how to cut glass PROPERLY. Ignore ALL the other videos, just watch this and do like he does AND DON'T TRY TO CUT TEMPERED GLASS !!! You can tell it's tempered as there is usually an etch printed logo down in the bottom corner, or the edges are ground smooth (arising, pronounced areesing), or rap on it with your knuckles and it sounds dead. If in doubt, don't cut it.
@@mrgcav I have heard people claim on numerous occasions that they were able to cut tempered glass with a laser, but I have never seen it successfully completed even though I have witnessed attempts several times, including a trip to Germany to visit a company who said they had perfected the technique. I was there as part of an emerging technologies engineering team to see if it could be done, however unfortunately the folks who claimed to have done it were unable to successfully repeat the process while we were there. Every attempt failed. So I am very curious where and when you had tempered glass cut with a laser? My initial reaction is that it wasn't actually tempered, even if it was supposed to have been, but maintaining an open mind.
Okay, question. I have a pane of glass for a table (5/16" thick), I deep scored it on both sides and I can't get it to break. I don't think it's tempered. How do I break this pane of glass that I have?
I saw a guy from India cutting thick glass like 1/2". He did 1 cut them simply tapped along the cut and you can see the crack continue along the cut line. Not sure if tempered or simple plate glass.
Hello there master craftsman someone of your skills could advise me what would be the best shockproof, waterproof glass and something resistant against fall would also love to cover it with a nantotech liquid for further resistance it will involve copper as well.Anyway the project is a laptop casing assuming I had the design and I could write that with a laser would someone in this trade be able to help me out cutting it as the very project will first be 3d and then we will see what goes from there on. This project of mine is actually an experiment with glass I need something water proof, shock proof, heat proof and something that would be resistant to breaking no scratches if it falls would something like that be possible and what would be your advice?.
Have you ever seen glass cut on a score and snap tile cutter? I have an old storm door I want to salvage the glass from for the lizard enclosures and I'm wondering if the breaker would cause cracks other than on the score line
I have a large piece of thick beveled edged glass that was the table top for a dinning room table. I want to repurpose it and use the glass for an aquarium build. I only have one piece so I can't mess it up. How do I know if it is tempered or not? It has beveled edges and I can't see if it has the film in between....I assume it is tempered because it was a dinning table top...very heavy and thick....please advise!! Help!!
I am going to suggest that if the glass is 8mm or thicker, and made in US, then it is possible that it's not tempered. If the glass came from China then it almost certainly is tempered. And I know that sounds wrong, but it's true. I retired a few years ago, and up to the date that I retired the US did not have a code requiring that furniture glass be tempered, while China did. I only mention China because a lot of furniture glass is imported from there. Furniture glass probably isn't going to be labeled tempered or not (although I have seen exceptions), so that makes it a lot harder to tell if it is or not.
Now show how to form ballistic glass... (I miss the tempered glass in auto side windows, used to be common to pop them for access at accident/fire scenes. Now half of them are using laminated or worse laminated gorilla glass. Makes it much harder to do extrications when you can't get through the glass.)
So does that mean you can cut a glass splashback if you follow your technique or not? I have a splashback that i ordered too long by mistake and need to cut it in half.
Hi Great question! Glass for backsplash should be tempered otherwise the heat from the cooktop would break the glass since normal glass will crack when heated up, so if you got if from a glass company it is tempered and you can NOT cut it Ryan
Hey man, thanks for the video. I had this idea to take old patio door and cut them to make home made, custom made windows.. I guess this is impossible, right? Thanks!
Depends, OK if it's laminated (unlikely) or (more likely) it's a TDP (toughened door panel) it will usually have an etch mark in one of the corners, with the maker's name and "toughened" and some numbers, this cannot be cut.
How do you start and end the score without chipping the edges. Especially at the beginning of the score. When I place the wheel at the very edge the end of the glass chips when I apply pressure. If I try to avoid that I end up having a very small part at the beginning with no score mark.
you might also be applying too much pressure on the cutter. If you see any flaking or chipping as you score the glass you are applying too much pressure.
@@thisisbig-o Thank you for the reply so quickly. I have learned from your video That the piece of Safety glass that I wanted to cut is pretty much a not a doable task..
I got a tempered glass magnetic whiteboard 4 X8. It's too big for our homeschool classroom. How can I cut it in 3 boards, since it has a metal sheet on the back?
Hi Noles If it's tempered glass you can't cut it. If you need 3 of them you have to get new ones, the tempered glass you have is the sice is is now or in a million pices
Probably way too late to reply, but if its a true glass/steel plate hybrid, the glass would have been laminated to the metal using a 10% or bright white PVB interlayer and the glass would not have been tempered. However the only realistic way of cutting the board into three pieces would be using a waterjet to do it, and I wouldn't consider that option unless the waterjet operator was very familiar with cutting glass.
I have a mirror that is thick and long, I want to cut in three, I have problems with my hands and no help what will help me cut this mirror what tools do I need
Hi. Off course Johnny, it was a type of alcohol I sprayed on, but it was not on the tempered glass, it was on the laminated, to soften and burn the foil between the to sheets of glass.
@@thisisbig-othank you! I left the glass industry after 16 years... but it's still in my head. I don't miss the frustration of working with it at times.
Cool video most people don't know much about glass except for the fact that it will mess you up. Why did they design tempered glass to shatter into so many little pieces? I understand that it's safer than a big chunk coming at you but a million little shards would be just as bad in your face or clothes or something no ? Cheers
Nah, not really, you can pick it up and rub it in your hands, it won't cut you. I'm not recommending it in your eyes of course but it shouldn't hurt your face.
Not so much designed, it's simply physics. Tempering glass results in surface compression and internal tension. Breach the boundary between them and you have a pile of tiny cubes all over the place. The little cubes aren't going to kill you, big shards can and do, that's why safety glass is required in certain applications.
@@trevorjames5493 you're welcome. If you want to learn more, just do a search for how is tempered glass made. There are some good videos on youtube showing the process.
I dont get it.. it was all over the place... not enough details.. How do I cut tempered glass? What tools do I use? Whats the maximum thickness per tool? What are the tool specs??
The downside to laminated glass as I learned through the same exact principle as automotive glass with tents on it is that if you use something to apply force to it say such as your right elbow well that glass will shatter and if you have enough force and momentum going you'll actually also put a hole in it but the downside is that the glass will remain together and it will literally cut the everliving bejesus out of you and cause you to walk into your mother's bedroom at midnight holding your arm wrapped with a towel because you were profusely bleeding everywhere because you're not only an idiot for shattering a '99 Ford ranger king cab window on the suicide door behind the driver's side but you also drink a whole lot of Jack Daniels so you're bleeding even worse than normal. I can also tell you that they will not put you to sleep in surgery and it's really not that bad having glass pulled out of your bone in your forearm as long as it's numbed up of course it was loads less painful than the following rejection I received from the smoking hot nurse who willed me out in the wheelchair that I asked out on a date. Just thought I would share that.
Hi and thanx! No I'm afraid you can not process tempered glass in any way onse it's benn tempered.. That beeing said you can try with some wet sandinpaper, might get a little better but you run the risk of shattering it.
Actually,you can arriss and flat polish edges on toughened glass with a belt sander using silicon carbide belts. Generally speaking though,all edgework is completed before furnacing.
When we get our glass, right from the factory. It comes tempered. We cut it up, in to smaller pieces. To make show cases. So there must be a way. It's a trade secrete. If you like. 👍 I'll explain it to you.
Hi Graham It's not tempered when it comes from the factory, it's float glass the factorys deliver and manufactur, it has to be tempered in an spesoal oven after its cut to size, the process puts the outer surfaces of the glass into compression and the inner surface of the glass into tension, you cant cut it ones it's tempered it would defeat the purpose of tempering in the first place 👍
After we cut it. Then we bevel the edges. Then we assemble the show cases You have to remove the bevels, if you want to cut it again. The bevels are the spine. Thanks. G.
Well I for one would like to see that. Spent half my life as a glazier, in the factory, on site, you name it and I have NEVER seen toughened/tempered glass cut. Are you sure you don't mean laminated?
Well...as far as I've been able to determine...""THE" absolutely biggest difference...is basically, the QUALITY of the glass-cutting tool itself. Because..when a person can put nearly all their body weight..into ""trying" to simply just make the score line..and STILL result in an incomplete or intermittent..or just...NOT be able to get the "CHEAP-ASS" cutting wheel, in the..cheap-ass glass-cutting tools, sold in..Wal-Marts.and .MOST hardware stores. Its WELL worth having to spend a bit more..and getting the RIGHT TOOL specifically FOR..cutting friggin GLASS. When you consider how much it can cost..in WASTING a LOT of glass, due to the obscenely POOR quality AND performance of said.."cheap-ass" glass cutters. I mean..Hell..I could just put a damn CARROT in a little box and throw a label on it that said, "Glass Cutter" and that friggin carrot..has about as good a chance as any CHEAP, so-called "glass-cutter", of...successfully.. consistently and reliably..CUTTING ant damn GLASS.
Anyone else here after scoring some glass and beating the crap out of it with a ball peen hammer trying unsuccessfully to cut it, only to find that it must be tempered glass?
Hi Andrew, That's the point, it can't be done, after it comes out of the oven and have been tempered it's set in stone, can't cut it, drill it, sand it or anything. Have a good 1!
Hey man good representation and I don't mean to be picky but I've cut enough glass in my day... so the end result is how you cut the glass, what I've learned in order to achieve that result is first you score it then you snap it then you have a cut piece of glass LOL when you scored it you said you cut it that is really not correct am I right? until it is another Separate Peace it is not cut again LOL but as I said overall good video thank you
There is an unofficial rule-of-thumb that you can remove 1/2 the thickness of the glass from the edge of a tempered lite by grinding or sanding, however it's not recommended by the glass industry and you increase the potential risk for the glass spontaneously shattering in the future by doing so.
I had to watch a couple of times but it was clarified in the comments. Trumpeted vs laminated are 2 different types. You can cut regular & laminated. You cannot cut termpered.
@@18T220 And you know that why? I have visited both Germany and Italy on separate occasions as part of a glass manufacturer technology team to view glass cutting lasers, and while the technology for cutting annealed glass with a laser is well developed, laser technology for cutting either tempered or laminated is, at best, sketchy. I have yet to witness a successful cut of tempered glass with a laser despite claims of success from some developers. I have seen successful cutting of laminated glass with a laser but only when the laminated glass was very thin.
Both of them are safty glass, just two different ways of making them, one is tempered and one is laminated, these days a lot of glass is tempered snd laminated, they combine the two for optimal strenght
@@thisisbig-o yep, although I would argue that in most cases heat strengthened/laminated is better than tempered/laminated, but that's not how folks on several ASTM or ANSI committees see it. They generally prefer tempered/laminated (balcony railings or balustrades for examples), but I chalk that up with being less familiar with laminated in general.
