How to Cut Glass Bottles 

Below are the step-by-step instructions for the three methods of cutting a glass bottle. Of course, no way is superior, and your choice will depend on personal preference. 

Method 1: Fire

  1. Use the glass cutter to score your bottle where you want it to break. Then, you can freehand it or use a stencil. 
  1. Hold the line in the bottle over the candle, rotating it every so often. Continue this for 5 minutes. 
  1. Dip the bottle in the bucket of cold water, letting the part you don’t want drop off into the bottom of the bucket. 
  1. If the bottle doesn’t break the first time, don’t worry; repeat steps two and three a few times until it does. 
  1. Use sandpaper to sand down the freshly cut edge, so you don’t injure yourself. 

Method 2: Boiling Water

  1. Use your glass cutter to draw a circle around the bottle where you want it to break. 
  1. Pour the boiling water over the bottle along the line you scored. It’s best to do this over the sink. 
  1. Dip the glass bottle in cold water, allowing the end you don’t want to drop into the bottom of the bucket. 
  1. You will need to repeat this method a few times for it to work. 
  1. Use sandpaper to sand down the rough edges before using your cut glass bottle. 

Method 3: Yarn

  1. Cut a piece of yarn long enough to wrap around your bottle where you want it cut. 
  1. Dip the yarn in acetone, wrap it around the bottle, and tie it. 
  1. Light the yarn on fire with the lighter, letting it burn all the way around.
  1. Dip the bottle in a bucket of cold water, allowing the part you don’t want to sink to the bottom. 
  1. Use sandpaper to smooth out the rough edges before using your cut glass. 

Some Safety Tips to Keep in Mind

Cutting glass deals with a few dangerous materials no matter what method you choose. Therefore you must keep the following safety tips in mind as you cut your glass. 

Watch Your Hands

The edges of the cut glass are very sharp. When you first cut your glass, you might be excited to decorate it immediately, but this could cause you to cut yourself. Instead, take the time to sand the rough edges of your glass and consider using something like resin to round out awkward issues. 

Don’t Make Drinking Glasses

You can make many things out of cut glass, but drinking glasses aren’t one of them. It is too dangerous to have yourself, a friend, or a family member drinking out of a glass that isn’t professionally cut.

But don’t be discouraged, as you can make unique vases, pen cups, and candle holders with your cut glass. 

Careful With Flame

Glass making

Almost all methods of cutting glass involve flame. Be careful when working with flame, and ensure you extinguish all flames when you finish your project. It is also a good idea to complete this project out of reach of curious pets and small children. 

Consider Wearing Gloves

Because all of the glass cutting methods include chemicals or materials that could damage your hands, it’s recommended to wear sturdy gloves while you work to cut your glass. 

Gloves will also help to protect your hands from acetone, flame, and boiling water, so grab a nice pair next time you are at the store if you plan to cut glass frequently. 

Don’t Rush

Many glass-cutting methods require patience, especially the boiling water method, as it will take a few times to get an excellent cut. Even though it may be hard to be patient, don’t rush cutting your glass, as using water that is too hot or trying to break it by hand may cause your glass to crack. Then you will need to start all over. 

Final Thoughts on DIY Hacks to Cut Glass Bottles

Overall, cutting glass bottles isn’t that hard to do on your own. No matter what you want to make, you can use one of the above three methods to cut your bottle for your project. Just be careful, and remember to protect your hands as you work because cut glass can be sharp.
