Q&A for How to Cut a Glass Bottle

It appears to be a candle flame placed under the neck/mouth-piece of a glass bottle to direct the heat into a more focused area.

That is much more difficult, and the dremel method is really the only one you can use.

If you just want a circular hole in the bottom of the bottle, like to turn it into a lamp, you need a diamond tip drill bit in the size that you want the hole to be. Each drill bit can be costly, so be sure of the size you want, and they're usually cheaper online than at a local hardware store. Follow the directions and practice on other bottles before you use it on your wine bottle, as drilling glass can be tricky.

Rubbing alcohol and acetone are wildly different chemicals. I’d recommend either getting 100% acetone from the nail polish aisle or going to the hardware store and asking for acetone. It’s cheap and not particularly difficult to find.

I hope this is a joke question. Gasoline explodes when lit on fire. Please do not use gasoline.

1. The flame isn't hot enough. This is why it should be acetone specifically, or, 2. The water is not cold enough. This is why it should be ice water specifically. Maybe even salt it and stick it in the freezer so it will be below freezing. It could also be both of these things.

A 22 millimeter diamond cutting wheel for glass should be available inexpensively online.

Absolutely not! I would take crystal to a jeweler. Let an expert handle that. It's much too fine and valuable for you to cut yourself. Even if you do find instructions online on how to cut crystal, I still would advise that you don't take your chances. Just take it to a local jeweler. Most of them sell crystal figurines and either know how to cut/size crystal, or can refer you to an expert in your area

Many nail polish removers contain acetone, or you can get some, it is available in most hardware stores.

You do this in exactly the same way as a bottle. Acetone and a string or any of the other methods described in this article are also appropriate for use with a glass jar. Just be sure to position the glass with care, since it will usually be shorter than a bottle.

Actually yes. Any liquid that will burn can be used. There is no special reaction between acetone and glass. Think of the chemistry behind it.

Paint thinner is usually mineral spirits and therefore not very flammable, so no.

if you are placing too much force on the bottle, then this will happen. Try using the heat methods only until it breaks on its own without any pushing.

No! Paint thinner is extremely flammable and the vapors it releases when set on fire could kill you. do not use paint thinner. It's best to use acetone, which can be found straight in most stores or in nail polish remover, which can also be found it most stores.
