Picture of How to cut a bottle with string and nail polish remover!
A wonderful use for a glass bottle is a container. However a container can only contain that which will fit in the hole. This solution to how to cut a reasonable good cut, quickly and effectively in a glass wine bottle will be instructed below.

I do hope you enjoy and stay safe! as this can be quite dangerous!

Step 1: Gather materials

Picture of Gather materials
To do this all you will need is:
Some string
1 Glass bottle (the thinner the glass bottles wall the better)
Acetone (Most commonly found in nail polish remover
Scissors
Some form of abrasive paper (I used emery board)
Sink filled with cold water (the colder the better. I used ice which helped)
Igniting source
 

use a saw and then grind the glass with a stone or what ever should work

I have a queston is anybody there?

tried it & it did not work for me. I re-fueled the string several times, too. Maybe my string or the glass was too thick.

Place in freezer to forget ice bath

Great tutorial. And a great story.
Maybe mineral oil would burn longer? Kerosene would but I don't know if it gets as hot
as some combustibles. Maybe pure acetone from the hardware store would prevent the re-fueling process. And some various sizes of sand paper. So you can save your Emory boards for your nails. Again, great tutorial. Thanks for sharing. (:

If you score the glass first you will need a much lower temperature difference and it will fracture where you want it.

what if you used several 'bands' of string at once, and wrapped a piece of metal wire around the bottle, under the layers of string?
Seems like it'll be a serious trial and error ordeal but definitely more exciting than using a glass cutter, I'm definitely going to try it!. How many bottles did you mess up in the process? or really what I want to know is what was the most common pitfall, thanks

Hello there :) Well the biggest trail and error thing I encountered was trying to get the temperature difference great enough. It's difficult to do but like I stated it's not just getting the bottle really hot, it's also getting the water really cold. However the nature of the glass that bottle was made of was very brittle and it ended up cracking quicker then I had liked it. The most common pitfall was that nothing happens lots of the time. I wish I had video of it and it does seem crazy but it is possible :) I only messed up the 1 bottle in the end ;)
Thanks for the reply!, do you think it's worth keeping the bottle in the oven on low/medium whilst the string's being re-acetoned?

Good question :)
To answer your question it would be best to leave it in normal air without going in the oven. What you want to do is create a very distinct band of heat difference meaning that the only place where heat should be is where the string is. If you imagine a thermal image of the bottle (you can google "thermal image" to understand what they are) you need a very thing bright ring around where the string is. If it were to be put in the oven the entire glass would be hotter, rather than that specific spot.

This method is a classic but has lots of draw-backs like those irregular edges.
I did a search and the method I prefer is this:

I've seen this before. It's very handy!
