Good video. I have worked in the glass industry for over 20 years Annealed glass is NOT heat-strengthened. Heat-strengthened is a process done to the annealed glass to give it strength. Heat-strengthened glass is 2x's stronger than annealed and tempered glass is 4x's stronger than heat-strengthened Annealed glass can be cut. However, heat-strengthened & tempered CAN NOT Insulated glass units CAN incorporate laminated glass The best laminate for impact of any kind is Sentury Glass Plus or also known as SGP. I hope others find this information helpful!
Who is here because he is a forensic student studying forensic analysis of glass? Btw youre video made a great visual representation for me thanks well done great quality as well!
my my, I am commiserating with whoever cleans the shop! Thanks for the laughs! In our little historic district I think I have heard of people using window film to strengthen 100 year old glass. Does that somehow bring ancient glass up to code for windows that are near doors and old doors that have windows in them? Thanks I learned alot!
@ 9:00 - 'insulated glass will fog up after 10 years'...there have been vast improvements with the sealing compound used around the edge - now they last a lot longer. We're working on a garden style window that is at least 20 years old and the seal is just fine, albeit there is oozing of the seal around the aluminum frame and we're looking for a solvent to clean it. We share the same sentiment for antique glass - cleaned, it is unsurpassed for soft light and tender fables.
Thank you for showing the different types of glass, and also for pointing out if they are DIY types of glass or not (whether we can cut it without expensive equipment). I realize we just have to get a glass company to cut it to size so that we can use it in our projects. What about sources for glass? Do you just go to your neighbourhood glass company and buy the more DIY-friendly glass by the sheets? Or would you try to find a wholesaler? I bought some strong glass for a table that I made, but it cost me about $80 CAD (cut to size, and edges cleaned up so nobody will cut themselves).
I discovered that glass super cleaned with window washing liquid can squeak when rubbing a wooly jumper. How strange. Can you explain why and how glass becomes squeaky when rubbing a woolly jumper.
Toughened glass & Laminated...are both safety glass !!.......Double glazed units ...can be made up of any type of glass in any configuration you require depending on your safety / insulation needs !
Awesome video. I have tempered shelf's that hold a lot of weight in my curio cabinet. (24in.x30in.) Could you do a video on the weight limits of different glass shelf's. Thanks
Good video, but a couple of incorrect points; Annealed glass is just regular plain ol' glass - the type you can cut and can cut you. It isn't heat treated like toughened and/or tempered glass, but I think the confusion here is that ALL glass is made through a heating process - hot enough to bring it to a liquid state for lack of a better word. Although I guess "molten" would be more accurate. Glass was discovered by finding volcanic glass or obsidian, and also lightning strikes. Modern glass is actually "floated" onto molten tin, which is why it's called "float" glass, so there's your heating process. But unlike toughened or tempered glass, annealed glass is put through a tempering furnace and the molecular structure of the glass is actually rearranged, and if and when it makes it through the process, it's stronger, and of course can still be broken but will shatter into tiny pieces (provided the furnace and person programming it is good), but it can still cut you. I have many scars on my forearms from it exploding in my hands, either while being installed or "spontaneous breakage", which can occur in approximately 2% of glass that has gone through the tempering process. And if and when that does happen, it is usually within days of it being tempered. AND no matter how many times it happens, it's still terrifying! So, the moral of the story is - stay in school and away from the glass business! JK, but it can be dangerous and what I've learned over the last 40 or so years is that like with most materials that can hurt you, it's most important to respect it and learn as much as possible about the properties of whatever it is that you were dumb enough to decide to work with! Again, JK and also again - nice video!
Hello dear, What would be the ideal glass for a 9/10ft in house office partition? Float or tempered? 8 mm or 10mm? 4th floor of a 12 storied building...pls ans
Laminated insulated glass is readily available, Velux skylights, by code, same for doors, double pane, with low e coating, is a must, 2018, no single pain glass
Sorry to be a contrarian here Sir, however you mentioned the last piece of glass that you did not break, aptly named insulated glass (IGU), and you stated that it could not be manufactured as Laminated glass. However, this is done routinely in the window industry today. By that I mean one piece of the IGU (usually on the exterior), can be anealed, Low E (or energy efficient glass) and the other piece (usually on the inside), CAN be manufactured as Laminated (two pieces of anealed separated by the film you mentioned between them, thus being laminated). This IGU gives you the best of both worlds, an energy efficient IGU which is also has the ability to not be easily broken through for safety. The rest of your demo was pretty factual : )
Linda, you may have misunderstood me. I said that you CAN get it tempered and you CAN get it laminated. The audio isn’t great in that part. After that I said that this piece isn’t safety glass basically implying that an IGU is in it of itself not safety glass. You would have to have an IGU with tempered or laminated glass in order for it to qualify as safety glass. Thanks for the feedback!
Safety glass or tempered glass can and will still cut you, just nowhere near as badly as plate or annealed glass. I know, because i've personally been cut by tempered glass, it was very minor and no worse than a cat scratch or getting scratched by a twig from walking through bushes. I get that everybody thinks that it's "safety glass" but one thing still stands, it's glass... and when glass breaks, it breaks into sharp pieces. When those pieces aren't as big, they can't cut you as badly.
Which glass is best and stronger, kids been throw stones through my windows. So please tell me which is stronger called shattered proof or smash proof please.
I may have just messed up. You didn't specifically mention plate glass. I was going to order 1/4" tempered glass for roughly 12"x 12" shelves in a cabinet to display rock samples on. But, I was recommended a less expensive option using 1/4" plate glass. If I'm careful with the larger rock samples up to 3 pounds will it still be ok? Where does plate glass fall in the strength comparison? Thanks!
heat strengthened glass goes through the same furnacing process as toughened glass but the quench cooling has a different profile and is slower reducing the amount of stress put into the glass compared to toughened, heat strengthened glass is around 2 times stronger than annealed, toughened is around 5 times stronger than annealed.
So what is the stuff that is sold at Lowes and Home Depot? and what should I use for the front windows of my 1924 Craftsfman bungalow. I prefer to have newer glass because I like the clear view but because its on the front porch, it would be nice for it to be stronger..
1/8” annealed glass would work just fine for your bungalow and will fit without modifications. You could pay about $8 per SF compared to $1.50 per SF for tempered if you really want stronger glass, but that is usually not necessary.

Your math is correct, but your sequence is not. Even in the US, glass is manufactured in mm thicknesses, not imperial or fractions. The mm thicknesses are then translated into fractional measurement because so many Americans are not familiar with millimeters and need to see the factions to know what they want. So 3.0mm and 3.1mm are both very common products and both are referred to as 1/8" 4.7mm and 5.0mm are both called 3/16" 5.7mm, 5.9mm, and 6.0mm are also common thicknesses and all are grouped into 1/4" 8mm is 5/16" 10mm is 3/8" 12mm is 1/2" 15mm is 5/8" 19mm is 3/4"
Hi sir, I like your video but it will be much better if you can explain on how to determine the type of glasses without even breaking it by simply observing it.
There really is not a good way to tell what type of glass by looking at it other than IGU because of the air space so I ant help you there. As for not breaking them, that just wouldn’t be any fun! 😉
Ok as a minimum standard, From this video I will be using thicker impact glass in my home then the one he was using at the end of the video. I’ll be doing a panel of one moderately thick impact glass per panel for one window each. Each window system will be containing a double panel.
You have gotten several things incorrect in this video. First, the antique glass is annealed. Basically all glass is at least annealed. Especially if used in windows or any manufacturing. And annealed is NOT heat treated. Second , tempered glass when shattered will certainly cut you. And IGU’s(insulated glass units) can incorporate any glass. Including tempered glass.
Laminated glass works great for sound reduction and so do Indow Windows. Check out this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-D5S_zximxCk.html
What low quality insulated glass do you have there. In Germany these are pretty much standard for multiple decades, and I have never seen one fog up between the sheets, even in old apartments 20+ years old.
Good information but not enough for me tell me something new because those all old version glasses tempered saifty laminated glass Double glaze glass built proof glass etc all are old
@@TheCraftsmanBlog No it is not, ...........Float glass is how glass is now manufactured, molten glass is floated on to a bed of molten tin which gives it a flat surface on both sides . Annealed glass.....Annealing is the process of slowly cooling the glass to alleviate stress in the glass ! Float glass is annealed glass..........
isnt annealed just float glass? can get from 2mm up to 24 or 25mm that ive seen. tempered/ toughen glass still cuts like a mofo depending on the thickness.
Get IG Units with laminated all the time. Needed for skylights or additional storefront security, etc. Otherwise good video except the part about not needing a glass company. We see failed attempts at customers trying to cut their own glass all the time.
You’re telling a do-it-yourself guy to tell people to not do it themselves? I think the folks can handle it if they are willing to take a chance and learn something new.
Interesting. Your synopsis on IGU’s I don’t agree with though. IGU’s are available in any configuration you want, ie: float, low E, tempered, laminate, decorative, or any combination of the above. Most manufacturers offer ten year warranties, I’ve seen IGU’s over forty years old. From a 25year+ glazier.
I don’t doubt that they can last longer than 10 years but why trust a product that is lucky to pay that long rather than a product that is designed to last hundreds of years with very little chance of failure?
I don't particularly understand why Tempered glass "cuts less" than regular glass, i don't know much about glass but small particles look more dangerous than the big pieces since you might not see them while cleaning up. Also tempered glass exploding like that gets me scared for people around when that happens, it looks like it could injure someone caught in the blast :P
It doesn’t really explode but simply fall into pieces. And as far as cutting, those little pieces can still cut but they won’t slice or impale anyone so you can walk away from the accident rather than what could happen with regular glass.
