Easy Bottle Cutting





Introduction: Easy Bottle Cutting

There are plenty of instructions like this around online, but they're all unnecessarily complicated and many use difficult or imperfect methods to cut the bottle. These steps are the simplest and most effective way I've found. I can cut a wine bottle in 2 minutes tops.

Step 1: Select Bottle/Remove Label

Start out with a wine bottle. They seem to be the easiest. Beer bottles are thinner, and crack more easily.
To remove the label just run under or soak in hot water. I used a metal spatula to scrape it off and a scrub brush to remove to glue.

Step 2: Bottle Cutter

or more appropriately, "score-er". I found this one online for around $15. There are many different kinds, but they all essentially do the same thing. Which is score the bottle all the way around, allowing you to use the method of your choice to turn the score into a perfect crack.
Make sure to apply steady pressure as you turn the bottle, and try not to slip. You want a straight line all the way around, and only one time around.

Step 3: From Score to Crack

This step in particular is the on in which the method is the best I've seen. It is faster, easier, and creates a much cleaner cut than most others I've seen.
Heat up some water in a kettle, but not to boiling. Pour it slowly over the crack, then pour cold tap water. Repeat until the two pieces of bottle separate. I put a washcloth in the sink so when the top falls, it doesn't break.

Step 4: Sand

Sand the top of the cut, and the edges, going from high to low grit.

That's it. Thanks for reading. If you have any questions, just ask.

    i haven't read too many of the other "cut a bottle in half" ibles, but this is basically "go out and buy this thing that's DESIGNED for this purpose and use it"...

    While I appreciate your opinion (albeit slightly unnecessarily sardonic) there are several things you should realize. Firstly, I am not endorsing a single product, there are a myriad of products that are designed to SCORE glass, including simple hand tools. There are several instructables suggesting different ways to complete the process of bottle cutting, and I feel as the the water technique is much better than any other technique I've personally seen, which is the reason for my sharing it. It's also not a part of any instructions that came with my product, or any other I've seen like it. I'd also like to point out, that while it's clearly a new concept to you, glass and bottle cutting is a craft that has been around for some time, and many people are aware of. It goes far beyond "cutting a bottle in half" as you so cleverly put it. Thanks for your input though, "CrapFlinger".

    awfully presumptuous of you to assume that i'm somehow completely unaware of glass/bottle cutting as a craft or as a utilitarian activity, especially considering that i made no allusions towards that assumption in any portion of my post.

    Well I apologize for seeming presumptuous. You're comment seemed to me to imply that you belittled the concept of glass cutting, or was not aware of it being as commonly practiced as it is. Nevertheless, I feel as though if anyone was being presumptuous, or simply sarcastic and rude, it was you. I feel like I should clarify that the main point of my instructable was to show/explain the aforementioned process of using hot and cold water to complete the cutting process, as opposed to a candle, blowtorch, saw, glass hammer, or any of the other commonly practiced methods used. Anyway, thanks for commenting.

    Well Put...thank you for the idea. Some people do not get the concept of idea sharing for the sake of passing along knowledge. Where would we be if this wasn't a common practice.(The sharing of information that is). Don't want to incite some type of verbal regurgitation about utilitarian activity from the big brain. By the way I'll take regurgitation for 22 points. There really is no opposite of " Utilitarian " other than something like frivolous and if creativity is frivolous than count me in where would we be without creative thinkers Duh.... living in a "Utilitarian" Society. Glad some of the greatest thinkers of my and any generation didn't subscribe to that type of thinking. Go jump in your Black Suit, come out your white house get in your gray car and go chase a rainbow. Unreal !! Thanks again I enjoyed your instructional and creative way to do this.

    Last step: sand down the edge. Check out the kickstarter campaign for a product that helps you sand the edge down easily. https://www.kickstarter.com/projects/582093084/the-bottle-bit


    Can you use this to make the old bottles into drinking glasses?

    I have been trying all night to get my bottles to break clean. What is the trick with scoring the bottle? My bottles keep getting hairline fractures going down the sides instead of clean breaks.


    I've been wanting to cut some bottles for quite awhile, but was a little uneasy about trying the burning string or torch methods and I've tried hammer methods years ago and had bad luck. So I wasn't doing it. -Now I will.

    I'm planning on cutting the bottoms off of mayonnaise (or other) glass bottles leaving the threads intact so I can take the lids on and off. Then I'm going to turn the bottle upside down, make a candle holder, attach it to the lid, maybe attach some form of handle, and make candle lanterns that will be easy to light and service.

    I'm also thinking I might make an adjustable air vent in the lid so the candle will burn steadier -better air flow- but the need and/or use of that will require experimentation.

    P.S. I think you meant to say "going from low (coarse) to high (fine) grit. - Seems backwards to me also (like wire gauges).

    Cool. Does this leave a sharp edge? How can I soften the edge if it is sharp?

    I could come up with many uses for this.

    i've seen tutorials online that say to use sandpaper. i'd use a fine grade- but also be careful of glass dust- cover your mouth, nose & hands (i've had glass dust in my lungs & under my fingernails.... hurts for weeks!). sanding under running water would probably be a good call

    yes. gloves & eye protection would be a good idea....it is always better to be safe than sorry.

    emery boards, like what females use on their nails, work wonders....only drawback to them is, you'll go through a bunch REAL QUICK...but they are the easiest to work with that I have found.

    One thing that you failed to mention is that the edge is very sharp & you can get cut very easily UNTILL you sand it down.
    It is best to round off the edge so that it is as smooth as the side. It doesn't take long usually.

    SON OF A....

    now why didn't I think of that??

    that beats tapping the glass anyday....AWESOME!!!!!

    I would appreciate it if you would tell me what brand name is on the glass cutter or where online did you find it using what keyword? I've looked at a lot of them and none are $15 or lower.

    I also just called Lowes and they have them for $4!!

    I found one for $11.09 here is the link


    you can get glass cutting wheels anywhere on the web or in most hardware stores. and when it comes to price you might just have to wait and shop around if you're looking for cheap

    Thanks Bob. I actually found an easy DIY bottle cutter that I might get around to making myself. As it is, I have a lot of projects that need completing or working on for 2011.

    Happy New Year!
