Instructables

how do i cut a wine bottle in half from top to bottom?

i am a chef and i want to use it as plate for a dessert feature so the edges have to be smooth and the cut has to be straight i thought of freezing water in the bottle and then cutting it on a band saw, but i have never used one before and i dont want to invest money into something that wont  work. any ideas i would love to hear them, thanks

I cut my wine bottles with a wet tile saw. makes a mess but cuts beautifully !!!!
Instead of cutting the bottle, have a glass artist slump it in a kiln into a half-bottle shaped mold. You'll wind up with something that looks very similar to a lengthwise-cut bottle, only without the sharp edges to deal with.
Something like this is already commonly done using a flatter mold to make little cheese board thingys, so the theory is sound. Making the mold should not be terribly complicated for a well-equipped glass artist.
As an added benefit, if you use a bottle with an enameled design (i.e. the Perrier-Jouet "Fleur" bottle), the design will be retained on the finished piece.
 You would end up with something similar to this:

(I've bought these for people before)

Good idea.  You're not so raving mad afterall.
That's very kind of you to say, but I think the space penguins would disagree....
Actually, I just realized you said "plate", so maybe the flatter mold would work for you. Those are available commercially, so you shouldn't have any trouble getting a test piece or two made, if flattish works for you.

It isn't really that hard. Just takes about 10 minutes though.

Score the glass where you want it to break with a glass cutter ($4 dollars at hardware store)

Then use a pencil torch ($10 dollars at hardware store, a lighter may work though) to rapidly heat up the score. Go over it a couple times, and if the glass starts to get a reddish glow, then you need to IMMEDIATELY remove the torch from that area and continue your way around the bottle.

As you move the torch slowly across the score, you will hear some popping and snapping as the glass separates.

I've done this with 100% success before, and I would love to help you, so P.M. me if you have questions.
FInd a glasscrafting studio - there are usually a couple in Yellow pages. A good one will have a diamond tipped bandsaw, and the polishing kit too

The idea seems interesting but lemonie is right about the difficulty and the necessity for specialty tools.
Have you considered using sugar glass instead? You could make a mold of a bottle half, then cast your sugar glass in the mold and coat it with paraffin to waterproof it. That way, even the bottle would be edible.

It's a nice idea, but hard to do. You would need a glass-saw, and grinding / polishing to follow. Also, the material would not be best suited to washing (without breaking), and you'd need a way to hold it steady on the table.
If you were to do this you may be best getting someone with the right tools & skills to do it for you. Also, have one bottle cut, use it & wash it every day for a month to see how it goes.
