He's ALMOST got it right. After cutting hundreds of bottles I have found that 1. You need boiling water, 2. A bucket of ice water. 3. Rubber O rings. I got them from the hardware store and they make different sizes, the larger ones obviously for the wine bottles. I have a hot water maker with a pointed spout, I slide the o rings on both sides the score. ( this concentrates the boiling water directly onto the score. while turning the bottle by the neck of the bottle I pour the hot water directly onto the score. For medium thickness glass I do this for 20 seconds, for thicker glass like Grey Goose bottles 30 seconds while turning the bottle. Then I immediately dip the bottle neck first into the ice water. When you put it in neck first this creates pressure with in the bottle and this actually helps to separate the glass. I have a success rate of about 80% using this method.

My mom cut bottles back in the 70s. She said you'd use the lightest pressure, just enough to disrupt the surface, and only slightly overlapping. Then she'd use a candle to slightly warm one side, (and only one side, other side she'd have a wet dish towel on the other side) and a flick of her finger. The tops would just pop off. The "cut" was so incredibly clean, every time. Often have a hard time even seeing the cut. She'd even do spirals, dips and other shapes. Imagine instead of cutting around, she'd cut vertical lines, along the length. Sorta kinda like a rounded off sawtooth pattern. My dad also made her a device that used electricity to do the breaks, and another device that did the same job, just a different way.(no heat of any kind) both were instant.

I just purchased a bottle cutter with wheels and glass cutter, In their video, they use the hot water and cold method. As in your video, it works perfectly. I thank you for confirming that this method works. I'm now reassured I made the right decision.

My mom bought a bottle cutter in the 70's. After a few projects with soda and beer bottles she quit it and sold it cheap to someone else. She basically made a few soda and beer glasses but even after sanding them everyone was afraid to drink from them because of the glass being able to be rubbed off. The next thing she bought was a rock polisher. That was around and in use for quite awhile longer. 70's project tools were fun enough but going picnicking at a dam , reservoir or lake had much more appeal. Edit: She wanted to make stemware from the tops but never got around to it. So her following project was make " tuits " in circular shapes...and would hand them to people after they would mention that they need to get around to it, to get something going. She would reach into her purse and hand them one little paper circle and say " there you go ". They would ask what it is or why she handed it to them. She would say, " you said you just needed to get a round tuit and I just handed you one. You knew when it happened because you would hear an exasperated voice moaning " Lydia ! " and my mom laughing really hard.

I love that "why" is the first thing you say to your cat when he meows.

One of the best videos about cutting glass bottles. Skip to 4:15 to see the cutting process Skip to 6:32 to see the splitting process I recommend watching all from minute 4:00

I like how you covered up the one imperfection on the bottle with your finger😂

I use a cheap Harbor Freight wet saw with a diamond blade. Makes perfectly smooth cuts in any glass bottle. My thing is guitar slides.

Thanks for a great video. You've covered all the methods of cutting a bottle and saved me a lot of trial and error (and bottles). Another fine example of "Internet Intelligence".

Just cut my very first bottle using this method. Followed the steps exactly and got a perfect cut. I love that the only 'specialty' item needed is the glass scorer. Thanks for the great info.

This is the most informative and helpful video on this subject that I have seen. I took your method and then came up with a way of doing it pretty quickly. I boiled a pot of water and kept it on the range at a nice boil. I had several bottles scored. As you mentioned, just one time around with a light score... Then I laid the scored bottle on top of the boiling water and rolled it for a bit. Once I figured it was good and heated, I took it to my sink. I ran cold water over the outside score line all the way around, then filled the bottle with the cold H20. The stress line is then cooled outside and inside. The bottom of the bottle falls out when I'm filling it (and keeping the bottle as close to the bottom of the sink as possible). I had placed a wooden cutting board in the bottom of the sink to prevent the bottom piece from breaking when it drops out. Perfect cut line! I then took another bottle, and repeated the process over and over because I still had boiling water on the range and plenty of scored bottles ready. If the bottle doesn't cut the first time around while being cooled at the sink I just stick it back in the boiling water and it snaps right off. I think having even heating and cooling around the circumference of the bottle also helps to ensure you get a nice clean cut. Thank you, thank you, and thanks again. I had given up on the process till I ran across your video.

You are the first I've seen that recommended safety eyewear. thanks for that.

you rock man!! I like how you are not just following the trend of cutting glass with burning rope, but you really revise the whole idea. Good job! respect!

Asking "what?" To the cat and the cat responding makes this video gold!

Wow, this 14 year old video is the best I have found on the bottle cutting subject. I seems to have done everything wrong on my first bottle cutting experiment :D

This is absolutely brilliant. thanks for being so generous with your hard-earned trial and error knowledge!

The best video I've seen so far for cutting glass bottles, and you have explained all the mistakes I did my first tries. Excellent job!

Un Believable!! Great!! Amazing!! You are a ROCKSTAR!! Thanks so much for sharing Dan!

Great video. Best technique I’ve seen. It works really well. Instead of buying a bottle cutting jig I screwed my glass cutter to my workbench and attached two pieces of 2 by 4 to the bench as well for positive stops for each bottle. Pulley adjustable. Cost me nada. Thanks for technique.

I was searching on KZfaq and I almost gave up ... Fortunately I found your video. Thank you.

I am finally able to cut a glass bottle!!!! U are genius!! Much simple and easy way to cut! Save water save energy!

If you keep a Styrofoam sheet in the bottom of the sink when you pour water over it, you can prevent the top from breaking when it falls off. :)

I have looked at every bloody video of how to do it, and I've broken more bottles and glasses than you've had hot meals! Thank you for showing us... Great job, Cheers Sean

I've just had to cut hundreds of bottles for a home project. I started with a rotary cutter which took ten minutes per bottle. I then found this video, and was able to cut each in less than 20 seconds. I owe you weeks of my life, thank you for this video! So much simpler than the ice cube and burning thread methods..

Stunning! I'm very impressed! Finally the correct and proper way to separate a glass bottle. Thank you Dan for sharing your knowledge.

Still the best tutorial and explanation after all these years.

I wanted to do some projects with wine bottles for sometimes now but was too intimidated to cut it myself. I have watched a few videos but something about yours gave me the confidence to do it and have a clean cut. I am getting ready to buy it a bottle cutter today. Thank you. By the way I loved the cat, it was like comic relief. I laughed my head off.

I just tried your method to break bottles, and I have to say it is the best and quickest. I only sumerged the bottles in iced water to make the impact even stronger.

My daughter bought me a bottle cutter some years ago. It cost about $10. She bought it at an arts & craft store and its quick and allot easier than any of the ways you've shown. I've used it for years on all kinds of bottles and never had a problem.

This should be the only video on how to do this. I wish I'd seen this when I first researched this topic. Thank you for this!

I tried, with disastrous results, to cut a bottle with my 4" angle grinder with a diamond blade on it. Hands down, that is the coolest trick I've seen yet. Better still, you showed all the flaws in the "tried" methods, and gave me a working procedure for cutting my bottles. Thanks

I have a project for biology that required me to cut a few wine bottles in half and your technique really helped me out, thanks

I was getting aggravated, saying 'just get to it, will ya' and then I saw the cat. I'm glad I didn't fast forward. Love that cat.

Amazing! It worked perfectly! My only feedback: Rather than a sink I used a large boiling pot of water and a large bowl of ice water. I used a measuring cup to pour boiling water over the bottle then I used a measuring cup to pour ice water over the bottle. I was able to control the final cracking so the wine bottle broke in the ice water. Thank you for this video!

I just tried this method about 20 minutes ago. I have never cut a bottle in my life but my first, and only 2 wine bottles that I used this method with came out PERFECT. Thanks Dan for such an awesome idea. my mom has about 100 bottles she wants to do projects with and you just saved us a lot of time.

Your hands down best I seen. Saw all videos of guys doing what you show not to do. Results all the same, jagged edges and unacceptable sloppy breaks. You had the cleanest , near perfect breaks out of all videos I found. Sweet technique thanks for lesson.

Bon Jovi has a KZfaq channel?! AND he’s a glass cutting expert? The wonders never cease.

Best I've seen, and very generous of you to share this technique. Thanks so much

Years ago they sold a wine bottle cutter and then you could use the top as a base for fancy stemware! Thank You for this video

why is there so many haters in bad comments on this guy he's not trying to sell anything to anybody he's just simply giving people the general idea of who may want a hobby you people need to lay off men watch it enjoy it or don't simply my opinion

FIRST 5,000,000 view video!

Very cool, thanks for the great tip. About 50 years ago my grandfather taught me to to use the flaming string method. Your method is obviously much better. It just goes to prove that sometimes a gentle touch is better than a lot of force.

Your system works. I used it last weekend while making beer bottle guitar slides. In the past I would dunk the bottle in boiling water--with mixed results. Your video shows a better way. Thanks.

Dan, you are a genius. The magnetic bearing, the solar death ray, and now this, the most delicate of all observations. Keep going forever please.

Best bottle cutting video I've found. Thank you for the great information and your time!

Used to cut bottles a lot when I was a kid, using the bottle cutter you have. I used the tapper it came with to break the tops off, and seldom got a clean break. Later I learned about using a candle and that was better, but still unpredictable. If I'd'a known your technique, I'd've got the results I was looking for. Too bad there was no Internet in the 70s. Thanks for the video!

I have a bottle I want cut and can't mess up. I've been searching through videos for different methods and this seems to be the winner for me. Thanks for posting!

I make stained glass and this by far is the best version I’ve seen online for cutting a curved glass. Good job 😁👍🏼

Awesome technique ! Was wanting to make guitar slides, so I got out my glass cutter from 1969, same one you used. But I had forgot my skill of cutting a clean edge. Will try your method ! Thank you.

Worked exactly as demonstrated. I appreciated the explanation of how it works, too.

I made a glass guitar-slide using this method! It really works. -And, I didn't even need that fancy bottle-scoring rig. I simply, carefully used a regular glass-scoring knife. ~Thanks!

Thanks for the video! I got a bunch of liquor bottles from a local bar I attend and I want to turn them into hanging pendant lights and thanks to you now I know the best way to start cutting them!! =)

Who else saw the imperfection he hid with his finger 😂😂

I've tried dozens of times and could never get a clean break. First time up after seeing this and boom ! Thanks a lot

Thank you for this. Spent the day doing the cutting right, and getting the heat stressing totally wrong. Appreciate the advice.

That has tho be the best way i ever seen to break the round bottles without having shards and pieces flying everywhere. Thank you for this video .

Great job explaining how, Top Level! Thanks. 👏🏼✊🏼🙏🏼

after watching this a couple times threw and trying it each time, i figured out that i was getting the bottle to hot and it was cracking the side of the bottle. after i did what the video says, lightly heat bottle with hot water then cool, add a little hot water, it snapped correctly, thank you.

Every video on this channel I watch, I'm non-stop impressed!

I really appreciate how informative you are. Start to finish the entire process was very easy to fallow! Great video

Just tried this technique and it worked perfect. Thanks

I'm a tiler and use a fine abrasive glass diamond blade in a wet saw for cutting glass mosaic. It also cuts bottles perfectly.

Best glass cutting i have seen. Brilliant of you to figure this out. You obviously went through many methods

Awesome job! Besides loving how nearly perfect that cut is, there are 2 other things that really impress me. One, is that you did it using simple tools that everyone would either already have or could get, AND USE, very easily (the glass cutting tool), and second, that ALL the "experts" said you're never going to get a perfect cut, AND YOU PROVED THEM WRONG AND FOUND A WAY TO DO IT. For everybody that is afraid to do something differently, or to even TRY, because you think that there CAN'T be a better way to do whatever it is, DARE TO BE DIFFERENT AND PROVE THEM WRONG. Just because everyone has been making a wheel the same way for thousands of years (okay, maybe not thousands), that doesn't mean you can't find a BETTER way. LOVE, LOVE LOVE THIS!

yes he knows what he talking about .works great only thing i could add is [lease remove the screw down lid the pressure was enough to blow it up in 20 peaces and it was a thick bottle !throw away lid .that way your heart won't try to jump out threw back bones ! took 10 yr's off my life span ! good to ya all.

Very impressive! I have looked at more videos than I can remember and yours is the most informed and successful.. Thanks

You are a true expert in glass. You know the properties of glass like no one I've seen out there. This is the best video and the best method I've seen. Thanks for your work and sharing with us.

Brilliant! For people making self watering planters you can check out other KZfaq videos but this kind of cut is exactly what you need!

Not bad, but I have gotten even cleaner cuts _with no scoring in advance_ by wrapping a *nichrome wire* almost all the way around the bottle/jar and applying a large current through the wire to produce *very concentrated thermal stress.* The wire needs to be fed through a heavy conductor like small copper tubes to prevent the part of the wire not in contact with glass from overheating. Getting the power level right is important, and the wire should not be too thin nor too thick. Something like 1/5 to 1/10 the thickness of the glass seems good.

I have a simple glass scoring plate that I use. Then I use hot & cold water alternately and get near perfect results almost every time. Happy to see a video that shows the same. I liked for the info but I subbed for the cat. 👀😁

I usually use water to cut bottles. Tried your method of pouring the water slowly and 20 out of 22 bottles have been successfully cut perfectly!!!!!!

That was awesome. Thank you so much! I’m getting a glass cutter tonight. I’ve been trying to figure out how to cut my wine bottles. You rock!

The trick my father and I used to open radio tubes was a trigger type soldering gun , we removed the tip and used a piece of bare 12 guage copper wire long enough to wrap around the glass , turning the glass as the wire is heating up . The progressive heat and vibration of the wire scoring the glass came out perfect every time 👍

Aha! My method was too sudden with the hot water... slowly seems to be the key. It works now!! Thanks! Now I need to get more bottles! I wish I could show a pic of how easy it is.

Thank you for showing us in Real Time!! I got an ER cut on my leg last year from one of those videos you talked about. This makes much more sense!

Your bottle cutting method is awesome. I did modify my old Stanley thermos for exacting pour over the cut line. 1. Drilled 1/16 hole in lid for air vent. 2. Drilled 1/8 hole and installed 1/8 brass tubing for precision pour. I also rolled the edge of the tubing to keep water flowing even like a faucet. Please note, any small diameter of tubing will work. Like metal brake line

I have been playing slide for over 30 years. Using other methods on KZfaq I used over 15 bottles I got 4 that will work. Doing it this way that Dan shows here, I had 3 bottles left, and I got 3 out of 3.....

Best tutorial I have seen so far thanks xx

Thank you Dan! I just found a cache of old bottles in the woods that I want to upcycle into a lamp but I need to cut the necks off to accommodate the bulbs. Your method indeed seems to produce the results I'm looking for.

You have provided the best explanation and an example of cutting glass - Thanks

Green bottles and especially wine or champagne bottles are great for beginners and learning the process. Clear glass and thin walled beer bottles require more experience. The thinner glass on beer bottles have many inconsistencies so the thermal stressing process requires a bit of skill.

This has been used for years by people in the know. Another very important piece of information is that you never go over a score line. It dulls the carbon steel cutting wheel. You use steady pressure and listen. Once you go all the way around and the score line connects you stop.

I know, years ago we did the same except FIRST we rubbed ice around the scoring, then did the hotwater pour to make it crack. Your way is great as you don't need ice ! Good Work !

I appreciated the preamble. This was exactly the amount of information I was looking for.

I made a bottle cutter by making a v-box you can lay the bottle in on its side with a glass cutter screwed down; scored a line; then used a nichrome wire in a circuit to heat it red hot. put the wire around the score line hit the power for a few seconds and the top falls off.

I got one of those glass cutters at very young age "Score then tap tap tap" They never came out worth A crap.I will try this.

Watched this at 10:00 pm, made a rig and cut my first bottle by 11pm, not quite even but a sticker messed up my cut. Thanks a lot! Great method.

Thank you so much. Opening a wine bar and plan to reappoint my empty bottles into water glasses. You have just made this something I will actually do!

just 1 thing. the vacuum u create when u place yr hand on top stops the leak not the pressure. excellent job. thanks

Super, thanks for the straight forward and simple info! Been wanting to cut a bottle that got stuck into one of my terra cotta watering cups.. they are not coming apart so I need the bottom cut off the soda bottle. Why should I break a good bottle? Thanks again!

Fantastic. You saved me so much time. Thank you. Using the low tech low heat low cold idea prevents discoloration to the labeling.

Thank you, for teaching us an easy to do bottle cutting technique.

Get a tile saw. $29 wet saw from harbor freight. Takes a few seconds to do

Put an elastic band each side of the score line. It will put the water exactly in the right place, hot then cold. Unfortunately not my idea, can't remember who told me.

Super underrated ! I tried all the others unsuccessfully until I came across yours ! TY very much !

Thanks for this! It took me a couple of tries, but the third glass came out almost perfect. Five minutes of sanding and I was enjoying a glass of water in a glass that I'd made myself.

Excellent video and commentary! Thanks so much! Please ignore the jerks who feel compelled to criticize you.

I use gallon costco pickle jars for terrarium

Great video - I am a wedding planner and have to cut 36 wine bottles for centerpieces. Thanks for saving me tons of time.

Awesome Dan! Best vid I’ve seen for simple glass
