How to Cut a Glass Bottle

Cutting glass can be done at home with very few tools. Beautiful bottles can be made into vases, lamps and more with often just a single cut. Get all of your supplies together before you begin because once you start your bottle cutting, you need to finish the job while the bottle is still hot.

Things You'll Need

• Bottle
• Support
• Glass cutter
• Candle
• Bucket
• Sand paper

Instructions

1. Put the bottle in a support that will allow you to turn the bottle but will hold the bottle vertically without tipping over.

2. Use a glass cutter to draw a line around the bottle where you want your cut.

3. Heat the line that you drew on the bottle. A candle works well for heating the line but do not allow the flame to touch the glass or it will turn the glass black. Turn the bottle slowly as you heat the entire line.

4. Go over the line with the heat five or six times.

5. Fill a bucket with cold water and submerge the bottle in the water while the glass is still hot. The extreme temperature change from hot to cold will cause the bottle to separate on the line that you cut.

6. Tap the glass bottle on either side of the line that you cut if the bottle does not separate on its own. Gently tapping the glass should cause it to come apart at the line.

7. Sand both of the glass edges with wet sand paper immediately after cutting the glass bottle so you do not get cut on the rough glass.
