Step 3: Cutting the Bottle (part 2)

Using a candle and some patience, carefully heat the bottle at the scoring mark rotating the bottle as you heat it. Hold the bottle with both hands, one on each end. I will typically heat the bottle for about a minute and then drip cold water on the area. Repeat the process until the bottle suddenly breaks apart. You will actually hear slight cracking of the glass as you do this.

The first time I did it I was very tentative but now it usually takes me only about 5 mins to cut a bottle.

Be carefull, the cut edges are EXTREMELY SHARP!

*Note:  I've also had success by heating the bottle in the oven for about 5 minutes at 225 F and pouring water over the score line.   You'll need to ruin a few bottles to perfect your method.
Hi there, I tried it this week and got the label off by soaking in hot water with a little dish soap. I even simmered the bottle (after cutting) in a pan of water. But I still have a lot of glue on the bottle. Will acetone get the glue off? Or do I need something else. I guess they're making better label glue these days.
<p>METHANOL cuts through adhesives like nothing. add a CLEAN, NEW razor blade or some 4 ought 0000 fine steel wool.</p>
<p>Methanol is a good solvent. It is also readily absorbed through the skin, and is toxic. Use nitrile or latex gloves, don't get it on your skin, and keep it away from all sources of ignition...it is highly flammable.</p>
i know that this is an ooooold post, but i wanted to respond. The very best thing for removing label glue residue is lighter fluid. NOT FIRE, just lighter fluid. it seems to be the perfect solvent for label adhesive. a little on a paper towel will often take it right off. a little more, and a green scour pad will take off the most stubborn sticker from a glass bottle.
<p>Lighter fluid is repackaged naphtha at a premium price. Look for VM&amp;P Naphtha at Home Depot or Lowe's. Around $7.99 a quart.</p>
<p>A quart of BBQ lighter fluid costs about 3-4$ at my local grocery store, so i'll keep using that. (the BBQ stuff has less odor than the lighter fluid for Zippo lighters) Thanks for the heads up though.</p>
<p>That's interesting. I found Kingsford Odorless Charcoal Lighter Fluid 64 oz for $6.97 at the Home Despot. The MSDS says it's 100% Aliphatic petroleum solvent, which is what naphtha is. I didn't know they now made it odorless. I have a gallon can of Coleman Camp Fuel which is also odorless naphtha. It was cheap at Walmart but now they don't sell it any more. I think because it is used by meth labs like so many solvents.</p>
I recommend zippo-type lighter fluid. It contains NAPTHA which is an awesome solvent for glues that can't be removed with soap and water. Definitely wash the glass thoroughly after using this, though.
Oh, and denatured alcohol works wonders here, too. Both of these options are much cheaper than products like Goo-Gone, but I think they work just as well.
<p>Naphtha is better. Denatured alcohol is highly toxic because it contains methanol, wood aclohol, that can cause permanent blindness, even just inhaling the vapors. Read the MSDS!</p>
I'll chip in in favor of the solvent made from orange peels. Just one tiny squirt of that stuff will strip most anything sticky off, even when alcohol fails. Never tried lighter fluid, but it would definitely be the stinkier option when you're indoors.
Goo Gone works. I've used it successfully several times.
Definitely going to second the notion of Goo Gone.
Chuck, I don't know if you have a dishwasher, but I put mine in the dishwasher and most of it comes off, then I take a scotchbrite pad and soapy water to get the remaining glue .. Hope this helps,,&lt;3
there is this stuff called 'googone', which is great at removing all things sticky, it's cheap, in the grocery store, and it smells great!
hmmm, I just looked at the MSDS for GooGone, and it's a mixture of mostly naphtha and a little of that citrus solvent and one other ingredient. Reading the comments here I detect a trend.
Try using WD40. With a little bit of rubbing it takes the adhesive right off in no time.
I heard somewhere that Mayonnaise will remove the glue residue left after removing bumper stickers. Maybe that would work on bottles too.
Most labels will slide right off after soaking the bottles overnight in a water and ammonia solution.
nail polish remover or some form of alcohol
I make cheese trays. I remove labels from wine bottles with a kettle of boiling water. Pour it into the bottle and leave it for 10 minutes then use a razor blade and some labels come right off in tact. Then I soak the bottle in a little soapy water and when the residue is soft I get it off with lighter fluid and razor blade.
I wouldn't use a razor blade, too much chance of scratching. As largejunglecat suggested, NAPTHA works wonders. Pretty much all lighter fluid that goes into Zippo and similar liquid fuel lighters are NAPTHA. (Haven't found one yet). Best bet: Go with Ronsonol Lighter Fuel (yellow bottle).
Baby oil is very good at getting sticker residue off of things....just put some on a cotton ball and rub the goo for a few seconds and it will come right off.
Goo-Gone is your friend. It never fails to remove adhesive from anything I need it off of, and has a clean citrus scent.
I used a razor blade scraper to take a lot of it off. some bottles come off clean, others take a little bit of work. you can also use Goof Off or something like that. Acetone might be overkil...
<p>&quot;Glass of course has a crystal structure to it&quot;</p><p>No it doesn't. Glass is unique in that is is what is known as a &quot;super cooled liquid&quot;. In science, the term <em>glass</em> is often defined in a broader sense, encompassing every solid that possesses a non-crystalline (i.e. <a href="http://en.wikipedia.org/wiki/Amorphous_solid" rel="nofollow">amorphous</a>) atomic-scale structure and that exhibits a <a href="http://en.wikipedia.org/wiki/Glass_transition" rel="nofollow">glass transition</a> when heated towards the liquid state.</p>
<p>Sanding down the edge is definitely the most tedious part of of the process. I would use the Bottle Bit. The kickstarter campaign runs through January <a href="http://bit.ly/1yjJBc1" rel="nofollow">http://bit.ly/1yjJBc1</a></p>
<p>Hi, there! I'm new to this site and new to glass cutting. I've cut a few bottles and have sanded them. It takes the edge off but leaves to rim cloudy looking. How do I get it shiny again? Would you be able to advise me on this, please? I read somewhere that polish could be used, but I do not know where to get it. Thank you so much.</p>
I am not crazy about the tools you uses to polish or grind the rim of your class. Fortunately, I have stained glass tools. I would use a stained glass grinder for the initial smoothing. There are various grinding wheels that provide the initial smoothing. Next, I would choose various level of wet or dry sanding paper to fully smooth the edge. My favorite winery, Iron Gate, in Mebane, NC offers one of its best wines in a blue bottle. Therefore I have no trouble getting quality wine in a blue bottle.
<p>I live literally 15 minutes from Iron Gate...I had no idea Mebane had other Instructable users. <br>Or that anyone on the internet would ever even mention the place. haha</p>
I have moved on to using a stained glass grinder since I first published this instructable. However, not all of us have access to such tools. Whatever you use, just be careful!
I haven't tried to do that with a candle before, I will have to give it a go. I have used a heavy wire bent in a tight loop at the one end to make a hammer and curved so it will strike the glass at a 90 degree angle from the inside. On the wire is a upside down triangle that is a friction fit. This allows you to swing the wire at the same height all the way around at the exact level of the score. tap, tap, tap, tap&hellip;.. pop.
Wow this is so amazing! I had no idea about how long making <a href="http://www.fantasyglassworks.com/wine-glasses.htm" rel="nofollow">personalized wine glasses</a> was around. I do have a lot of dimpled glasses at home. Why do they design the bottle that way?
oooooooh! That's new. I gotta make me one of these <a href="http://www.corkwine.ca" rel="nofollow">wine</a> bottle cups. It'd make a good Christmas present for my parents.
a much better way of breaking the glass in a &quot;controled manner is to score a line around the bottle only once and then to slowly pour hot water then cold water then hot water then cold water and then pop viola its in 2 nice pieces..... way better then breaking and using a candle <br>
In summary nothing new to me, BUT:<br>You had a very smart idea there with the protection with duct-tape!<br><br>If i saw that correctly, you used this Aluminum-type-duct-tape for this?<br><br>Also normally i dont use a candle to stress-break the glass at the cut. I simply hold them under the hot water from the faucet and &quot;shock&quot; it with cold wather from the faucet. Repeat once or twice and you have a very nice cut.
Hi! If you use the wire brush to leave a metallic sheen, is the glass dishwasher safe (or drinking-safe)? Or will that sheen eventually fade off with use/washing over time? Thanks, great instructable!
If the wire wheel is made of steel (even stainless steel), I'd be worried about it rusting over time, but it may wear off before that. If the wire wheel is Aluminum, it will also oxidize, and dull. Some people will argue that excessive amounts of Aluminum can have toxic effects, but since the average person is estimated to consume 3-10mg of Aluminum daily as it is, I doubt that even if you ate the rim it would be a problem (much less so than the lacerations such an act would cause...). Nonetheless, at least a heavier metal, like gold isn't being used, which has well known toxic effects. The metal is most likely deposited as the wires pass over the rough crystalline structure, and as the wires help break off minute, weak, and incomplete pieces of the matrix, thus smoothing it, larger pieces of the matrix will become impregnated with metal scraped and broken off of the wires, also effectively making the surface smoother, as long as the metal is retained. How you handle these glasses is up to you.
While gold can cause heavy metal toxicity, it's extremely rare. The human body isn't able to digest gold in pure form, and it typically passes through without harm. There are forms of gold that can be absorbed, typically used in folk medicine. Even in these forms, dosages have to massively exceed recommended levels before health problems arise.
<p>Easier method using thermal shock, any flammable liquid would do, see this video:<br /> <a href="http://www.break.com/index/how-to-cut-a-bottle-with-a-string.html" rel="nofollow">www.break.com/index/how-to-cut-a-bottle-with-a-string.html</a><br /> &nbsp;</p>
But does it work on wine bottle's???
The string method is very crude imo and will not work well on wine bottles.
Tnx :)
thats amazing.
i can not find the BC Quick Cutter. Please help
Beautifully done! I've seen it done similarly with just a simple glass scorer here: http://www.diypics.com/how-to-cut-glass-bottles/
Could you cut these with a wet saw?
<br> Thanks a lot for the info, I had never know about to make glass from wine bottle. Thank you so very much for sharing it with us.<br> <a href="http://www.designercrystal.co.uk/Type-Crystal-Decanters">http://www.designercrystal.co.uk/Type-Crystal-Decanters</a><br>
how do you go about smoothing the edges, so as not to get cut??
