About a year or so ago, I found myself shopping for a bottle cutter. I spotted an inexpensive one at my local craft store, and since I had a project in mind that required a bottle cutter, I bought it. As it turned out, that wasn't a good idea. It didn't cut so much as scrape. Plus, I wanted to cut slanty bottles (at the neck, actually) and it certainly wouldn't do that. (Can any cutter do that?) I put it back into its box and stuck it in the closet in my craft room and that's where it's been ever since. Now, after seeing so many more great recycling projects out there, like the tumblers pictured above, I want to give glass cutting another go. So, to make a long story a short question...what's the best bottle cutter on the market?

Hi Lori, Of course the glass is not tempered, all beer, glass, wine, bottles and vases are NOT tempered. Tempered glass can NOT be cut (unless they are annealed / un-tempered) because they shatter into a zillion little pieces. The comments were irrelevant. If you can place a straight score line around your vase, and your apply a proper breaking process like the one in my video link below, you can get a nice straight cut.  The alternate process is to cut with a diamond saw. If you want to go that route, contact a Lapidary / Rock & Mineral club in NJ. There are lots of them and they all have the necessary diamond saws used in cutting glass, rocks, gemstones, etc. For a few $ I am sure one of the members would cut the vase for you.

Cheers, Murray

Hi Murray,  This is Lori P. from NJ.  I wrote you back on Aug. 25...regarding changing a vase into a "lamp" shade...I purchased a round bottom with a ruffled top cranberry vase that needs to have the bottom cut off in order to fit the base of my Victorian lamp.  I have called many stained glass stores in the NJ area and not one of them have a bottle cutter - can this be accomplished with only using a diamond blade table saw?  Some of the stores have said that the vase is not tempered glass and would cut unevenly???  What should I do???  Thanks again.  Lori P.

Part 2.

I user a set of 6 drums with sandpaper grit sizes 60, 120, 220, 600, 1000, 2000 and I sand for about 1 minute with each drum, dipping the glass in a container of water to wet it which avoids dust.  You can also purchase diamond coated sanding drums but they are in short supply and difficult to find.      I have not yet tried the SaberTooth sanding pads. I think they would be good in combination with the sanding drums. The 60 grit pad would be useful to make the 1st coarse grind to take the maximum amount of that sharp edge off. After that I would proceed with the sanding drums.  I think that the gaps between 60 to 400 and 400 to 2000 are too large and don't produce the best results or require a lot of elbow grease if you are looking for a nice polished edge. An analogy I would give you is your finger nail and a fine nail file. Cut a 1/8th " notch in your nail. Now try to file the entire nail down to get it level with the bottom of that notch. It takes a long long time. Its a similar problem with glass or gemstones which are very hard substances. When you use a 400 grit abrasive to grind down a 60 grit deep groove it takes a long time or what usually happens is that you leave scratches because you don't go all the way down. But if you don't care about the aesthetics of the edge and just want to smooth off the sharpness, then one or two grit sizes will do the job.      


Cheers, Murray

Part 1. Hi Denise, (2 part reply due to character limit)  I'm glad the video was useful. You should be getting 100% success so if you would like to describe what the failing cuts look like, I can offer some suggestions. For example, when you immerse the heated bottle into the ice water, it is important to dip it in with the closed end first so that the outside of the score line is exposed to the ice water but the inside wall is not. Or stated another way, do not plunge the bottle in upside down. And of course, a  continuous score line is critical.    Regarding the sanding of the cut edges, I can speak quite a lot from having tried numerous tools and techniques.  My current process uses a set of 3/4"  sleeveless sanding drums (for use with any electric or battery drill) some info of which you can see at the link below to Lee Valley Tools. I buy standard 9" x 11" sheets Silicon Carbide Wet/Dry sandpaper which cost about $1.50 each. I cut each sheet into 12 pieces (the drum requires a 2" x 3") so each drum sleeve costs about 15 cents. A sleeve will do about 5 - 10 bottles so it's very economical once you invest in a few sanding drums. These drums are made by a company in Greensboro N.C. but with the Canadian $ so low, you can order them from Lee Valley Tool for approx $12 U.S. each. How many you but depends on how much time you want to spend and how smooth and shiny you want your glass edge to be.

Denise,  I just received my sanding pads from Kinkajou Sabar Tooth!  They are awesome and work the best out of the many pads I have tried.  I can get the beveled edge n about 5 mintues with these diamond pads.  One is 60 grit and the other is 400.  The kit also comes with 2000 grit paper.  Before getting these pads I had such a hard time getting that bevel.   

Denise on Aug 27, 2015:

Good Afternoon Murray, Thanks for the video again. I've been practicing and have had great success and flops. But I do have one question what do you recomend using to sand the edges when I'm done.

Thanks Denise

Bobbi on Aug 26, 2015:

I guess Ishould also say the hole/circle needs to be big enough to fit a candle through.

Bobbi on Aug 26, 2015:

I have another question.  How do you cut a hole in the middle of a bottle?    I want to leave the bottom in for support of a candle.   And of course the bottles Ihave seen look to be beveled too.  

Lori on Aug 26, 2015:

Hi Murray, Thanks so much for the info...I forgot to mention that the body of the vase has square corners, but where I want the cuts to be made is rounded...would that be a big problem for a glass cutter?  Thanks again.  Lori

Murray on Aug 26, 2015:

Lori, I live north of you but it's in Canada and do things cross border has a number of impediments. I suggest you search for shops that do stained glass products. Just check your yellow page listings under stained glass. They all have workshops with the right tools including diamond blade table saws. Since you only need to cut off the top and bottom, the saw would be a solution. But many of those stained glass shops have bottle cutters and other devices so they should be able to help you.

Cheers, Murray

Lori P. on Aug 25, 2015:

Hi Murray, I have a pink colored glass vase that I need to cut the top and bottom off, so I can use it as a lamp shade...how do I find someone who can do this for me?  I sure don't trust myself...I have tried to look up professional glass cutters in my area and the search still gives me the different types of bottle cutters on the market.  Is this something you could do for me???  I am from NJ.  I would be very grateful for any info you could provide.  Thank you.

After much experimentation, I have come up with what I feel is the best way to cut a glass bottle. Consistent perfect results, safe for all bottles including ones with plastic and paper labels, No boiling water, no flames, no candle flame, no combustible fluids, no propane or butane gases, no strings, or masonary saws.  Just uploaded a Youtube Video. Here is the link:

Murray on Jun 05, 2015:

Hi Denise, getting a successful, clean separation will require different conditions depending on the thickness of the glass, the type of glass, the area on the bottle where the score line runs, and the process being used to thermally shock the bottle.

I can provide you with my personal info via email if you would like to contact me   marvie10@gmail.com  

Cheers, Murray

Denise on Jun 05, 2015:

Thank You Murray, where are you located address and I can see how much it would be to ship them I don't mind doing it myself but I don't have alot of confidence. Do you recommend practicing on alot of botles before cutting what you want/

Thank You

Murray on Jun 05, 2015:

Hi Denise, The key issue for you is not going to be the cost of me cutting the bottles, it will most likely be the cost of shipping bottles back and forth. It doesn't take too many $30-$40 shipments back and forth to equal the cost of a Creator's Bottle Cutter which I have seen on Amazon and other places for $99.  If processing Pendleton bottles is a one time event then purchasing the cutter may not make sense. However if you plan to cut other bottles to make drinking glasses, mugs, lamps, etc, then the purchase would likely make a lot more sense.

Cheers, Murray

Denise on Jun 05, 2015:

Good morning Murray, I have been reading your post in response to bottle cutters. Would you be interested if I pay for shipping on cutting some Pendleton whiskey bottles for me. If so what would you charge or do u think I should buy the creator kit you recommend?. Thank you


Murray on Apr 29, 2015:

Thanks Ray, it's great to see that there is a device in the market that can actually score square bottles. So many of the liquor bottles that are readily available for up-cycling are square and rectangular. and those tend to have some nice embossed and applied ceramic labels on them.

Ray on Apr 29, 2015:

That's great news Bobbi. Enjoy.

Bobbi on Apr 29, 2015:

HI all,   I think I have FINALLY got into the art of bottle cutting.   I was not having a lot of luck with the traditional cutters, especially with the square bottles.  I purchased a diamond blade for my wet tile cutter.   Life is so much better now!  Out of the last 10 bottles I got 8 proper cuts.  It would have been 9 but I tweeked a rough edge and craked the 9th one!  No bottle is safe from me now!

Just wanted to share this video of the CBC scoring a square bottle. https://www.youtube.com/watch?v=TsnhNcY308Y
