Bottle/Glass cutting

[16again]

Alright guy’s, girlfriend wants to sell flowers in cut wine bottles. Worked 13 years for Home Depot and cut tons of glass. Bottles however, I’ve never cut. Any easy ways to do this? Thanks in advance!

what part are you looking to cut?

I have done it a few times by hand, using a standard glass cutter and tape to give a reference line around the bottle. Once scored I would take a kettle full of boiling water and slowly pour it onto the score line while turning the bottle. Then I would immediately put the score line under cold water coming out of the faucet. Sometimes the cuts came out perfect, and other times the cuts were uneven and had cracks. Next time I do it I will definitely invest in a jig like what was posted above.

String, acetone, fire and cold water.

Wrap the string tight around the area you want to cut.
Soak in acetone.
Light on fire.
Douse in ice water.

Should cut the glass right along the string and leave a smoothed edge.

Guy’s/Gal’s I’m looking for actual experience here. She wants to sell them as vases for a potential floral business.
Thanks [emoji1317]

I saw them doing it at some hippie craft fair thing, string fire an ice water.

Follow up w/ increasingly fine grit sandpaper on the cut.

I sort of recall a bottle cutting kit in the 70's sold on TV or whatever, and bottles are different than plate glass, and very susceptible to breaking when cut .
i may be wrong, but just an FYI

Lol, Cobbler, I’m pretty sure I used that kit back in the day.
Was hoping there might be something more “up to date” [emoji23]

Previously (for curiosity's sake), I've cut a bottle with - a carbide grit rod saw - and a carbide grit hacksaw blade.

The later worked better than the former, but neither produced what I'd call satisfactory results. (Though, the blade is an excellent tool to have in your tool box.)

Now (for curiosity's sake), I consulted the inter-webs.

This seemed well worth the read - lots of pictures and important safety advice.

There is a company that sells beer bottles cut as glassware. I'd try either contracting this company or asking this company.

A tile saw with a glass tile blade would work too.

Knock the bottom out with a knife down the neck, stab it a few times around the edge and a final wack in the middle.

I remember when bottle cutting kits were all the rage back in the 70's. There was a gizmo that fit in the hole, and a glass cutter you went around the bottle with. Originally, you were supposed to tap gently around the scored line until it separated, but that method was unreliable, especially with larger items like gallon jugs. We used to fill the bottle with motor oil up to the score line, then stick a red-hot iron poker into the oil. You'd hear a 'click', and the top would be separate. Messy process, but very clean cut. My sister liked to cut gallon bottles to make food and water dishes for her cats. We would sand the edge smooth and take the sharp edge of with sandpaper.

I remember I was quite proud of my set of juice glasses I made from Michelob bottles.

HF tile saw and good blade.

Thanks everyone. Much appreciated.

This triggered a memory. I cut nearly a hundred wine and champagne bottles with one of those kits for a fund raiser my wife was involved in. It worked pretty good most of the time. I wet sanded the two pieces smooth (up to 600 grit) and then epoxied the cut off neck to the bottom of the bottle to create pedestal glasses and candle holders. Good times.
