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.

I got tempered glass cut with a laser.

[@gregcorwin8316]

@@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.

I only have one piece so I can't mess it up. How do I know if it is tempered or not?

[@thisisbig-o]

Hi Shane Sorry for the late comeback, I would agree with you, since its been used as an table top there is a real good chance that its tempered.

[@gregcorwin8316]

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.

[@Blazer02LS]

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.

[@BlackFaceTrudeau]

@@stewartmcmanus3991 Thanks Stewart!

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.

[@thisisbig-o]

I guess it's a thing that comes with time, but you don't have to start at the very edge, you can leave a couple of mm 👍

@@thisisbig-o Thanks

[@gregcorwin8316]

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.

[@gregcorwin8316]

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.

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

[@stewartmcmanus3991]

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.

[@gregcorwin8316]

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.

So overall safety glass seems to be the best of the 3. Not only does is it safer but you can cut if as well.

[@thisisbig-o]

Yeah, laminated is the best in my opinion

[@jasoningram2006]

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.

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 👍
