How to Cut Glass Bottles Horizontally

Updated March 23, 2017

Glass cutting is a great way to make crafts that are beautiful and original. A glass bottle can be the base of a lamp, vase or a piece of art with just a simple cut. Cutting the glass across horizontally requires a little bit of practice, but is well worth the result. Make sure you are prepared when you start your glass project since you will have to start and finish your project while your glass is still hot.

Support your bottle. You can purchase a bottle support from a local craft store. If you cannot find one, you can use a bottle cover that will let the bottle stand without falling over, but also allows you to manipulate your bottle.

Slightly cut your glass.Take your glass cutter, and draw a line where you want to cut your glass. Go horizontally around the bottle with a light pressure. If you press too hard, you will break the cutter or the bottle, or perhaps both.

Put a candle to the line. Using a candle, or even a lighter, heat the line that you made with your glass cutter. Make sure that the flame does not actually come into contact with the bottle, as it could discolour the glass. Make sure that you turn the bottle around to heat all the way around the perimeter.

Dunk your glass. Put your glass into an ice cold bath of water, either in a bucket or bowl. The temperature moving from hot to cold will cause the glass to move apart on the line that you made with the glass cutter.

Tap the bottle. If your glass does not seem to be breaking apart, you can gently tap the side on the line that was made with the cutter.

Finish off your bottle. With wet sand paper, you will want to sand the edges of your bottle to make it safe to handle.
