Recycling glass bottles for craft projects often requires that they be cut to size. This is a guide about cutting glass bottles.
I work with stained glass a lot and often use the bottoms of wine bottles in my windows. The bottles with the pushed in bottoms look really cool with the sun shining through. It's a fair bit of work to get the bottoms cut and shaped for use, but well worth it.
Check on YouTube for several different ways to do this. I have over 30 years experience working with all kinds of glass and have cut up hundreds of bottles.

Here are instructions for making a jig to help hold and cut bottles.
On our first attempt, we put the taller board to the back in assembly.
This is a picture of the tapper all together
Lay bottle in jig, making sure that bottom of bottle is firmly against bottle stop. Score with bottle cutter, resting hand on the hand rest. Score and then rotate the bottle. Do not repeatedly score bottle as this is a waste of time and makes the bottle harder to cut. Repeat this until you are all the way around the bottle. Insert tapper and gently tap around the score line until you hear a small cracking sound. Continue until bottle is apart.
Note To Users: Be ready to tap the cut soon after scoring. Any lapsed time and, believe it or not, the glass will heal and be almost impossible to break.

I want to know any way to cut a spirit bottle down to make a glass.
First get yourself a bottle cutter don't try the String and fingernail polish remover or any of the other suggestions. I bought mine at Michael's you need to score the bottle with a glass cutter it only needs to be a light scratching sound you need a real fine line cut into the bottle and I have recently found the best way to separate them.
For years I was tapping as it was suggested and the edges were never straight if I didn't break the bottle after doing your scoring, over a sink with an old towel on the bottom pour a very fine stream of boiling water over the scored line rotating bottle to heat the glass evenly and keep the stream as fine as possible then immediately run it under the cold tap water you will hear a little ping or popping sound at this point the glass may separate if not repeat the boiling water and must be boiling (I keep 2 tea kettles going) over the scored line again you'll actually see where it has separated rotating the bottle I have found This gives the smoothest this separation.
Then use sandpaper for glass to smooth out the very edges I just put the sandpaper emery cloth on an old thin towel on a flat surface and rub the bottle on it in a circular motion with very little pressure I keep checking to make sure that it is being sanded evenly once the hole Cut edge looks frosty It should have smoothed out all the rough edges so no one will cut their mouth.
And for all the ones that don't make it if you know anyone with a rock tumbler, break up or cut the pieces put them in the tumbler with a couple of rocks and some sand let them tumble for a couple days You now have see glass.
Does anyone know how to make the wine bottle edge? After cutting the bottle how do you make the edge smooth and melted looking, not sanded? I have a kiln, and already slump bottles. Any clues, anyone?
You have everything you need, if your kiln is big enough! Just stand it cut end up in the kiln and heat slowly to about 1400~1700 F and keep a close eye on it. With the cut end towards the top it should get hotter quicker than the bottom. When it looks rounded to your liking, flash cool it to a temperature. When the glass is stable, then cool to room temperature like any other project.
You can also do this with any torch that has a blue flame. You will still need to bring the whole bottle up to temp. before tying to round over the top edge, or it will shatter. Just remember, glass does not like to change temperature up or down quickly, and you will be OK.
PS. Figure on a few failures, and take notes!
When making a drinking glass out of a beer bottle, what type of string do you use to soak in lighter fluid, then tie around the bottle?
By Alex from Sheffield, MA
In the 50's, when I was a wee widdle kid, we used postal twine, a cheap hemp string, tied to the top and bottom of a thumb-thick willow stick, like it was a fiddle string. Looping the string completely around the bottle, turned the fiddle stick into a bow. "Sawing" rapidly heated up the glass and splashing water on it cracked it.
In the 60's we got lazy and used butcher twine and white gas.
In the 70's they sold bottle cutting jigs, that let you roll a bottle in a V shaped trough with one end stop and a glass cutter.
I improved on that by drilling two holes into each side of the trough and gluing marbles into three of them for smooth sliding bearings, and the glass cutter into the fourth hole.
For the neck side end stop I just clamped a block of wood into the trough with a C-clamp.
For the smoothest rotation I wrapped a strip of rubber cut from an old bicycle inner-tube a couple of times around the bottle and out through a hole in the bottom of the trough. That resulted in smooth and precise cuts and the 100th bottle was cut exactly the same as the first.
To get the edge perfectly smooth I always used a torch. As long as you never stop and keep the torch moving around the top, it works quite well.
Keep in mind, though, even with a perfect cut and a perfectly beaded edge, cut bottle glasses are just a goofy novelty and will be retired to a shelf or given away pretty soon. They are not comfortable for drinking, but if you use colored bottles, they can be used to make very pretty storm candles.
I would like to make glasses like these from the Pottery Barn. However, I have never worked with glass. Any ideas on how to cut the bottles, and then smooth the edges? Thanks.
If you Google "bottle cutter", you will get lots of results that have the special kit; and it should include the emery cloth to smooth the edges. It should also have good directions for all steps. I saw nice kits for $29.95. (01/02/2009)
This idea has been around for years. When I was a child, my father bought a kit to make his own glasses. He used beer bottles, Pepsi bottles, and any other kind of bottle that suited his fancy.
He did find the kit at one of those " As seen on television" stores. (01/08/2009)
We tried this years ago with a kit. We never were able to use any of them. We couldn't get them really smooth. It always felt sandy and for the time and trouble, it was cheaper and easier to buy glasses, even second hand if you really want to be frugal. They were also ugly and never looked right. (01/08/2009)
There are several video's on youtube showing how to cut glass bottles. I watched them last year because I was going to try it, you know how that goes. It's still on my "like to try list". If I remember, you take cotton string or twine, soak it in nail polish remover, tie it on the bottle where you want it to be cut, set it on fire, and then submerge and snap off the top in a bucket of cold water. (I think the sudden change in temperature breaks it off.) Then you wet sand it smooth. Good luck and let us know the results! (01/08/2009)
They never come out right. If you'll notice on your regular drinking glasses, the edge is slightly rounded. The straight cut glass never "feels" right when you drink out of it. (01/13/2009)
This was a popular shop class project when I was in high school back in the 1970s. You cut off the neck of the bottle, glue it to the bottom and it becomes the stem of the glass. You do have to use a special glass cutter, which I believe you can get at a crafts store. They are novel, but the big problem with this type of glassware is that the sides of the glasses are so thick so that when you drink out of them, they dribble. I say don't waste your time. If you are looking for fun, frugal glassware, try the mason jars that ready-made spaghetti sauces (like Classico) come in. They work great, are good quality, hold a lot, and are fun to drink from!

To make edges of glass smooth to drink from, use sand paper and oil, it works great. (05/04/2007)

First of all you cut the beer bottle or wine bottle, then you go to any auto parts store an get some valve grinding compound. Put the valve grinding compound on a sponge and wet it. Then you lay the sponge down and turn the glass up side down on the sponge and start twisting. The edges will come out smooth and rounded. And that's how to make drinking glasses from glass bottles.
