There are countless ways to cut or to break a glass bottle or jar and having tried them all I thought it was about time I shared my favourite method with you. This method is fool proof. Its quick and easy and leaves you with the cleanest cut.
There are some more convoluted and elaborate methods out there for cutting glass bottles but you really don’t need to be putting anything in the oven, blow torching anything, heating wire, string or putting bottles into freezers, so cast those ideas to one side.
Cutting a Bottle with a Glass Cutter and Water
What You will Need:
1 x hand held Glass Cutter
Running Cold water tap
Rubber glove (to hold the bottle whilst pouring boiling water)
Steps to cutting a glass
1. Make sure your bottle is clean. Any dirt or grit on the bottle will mess with the cutter.
2. Use your glass bottle cutter to make a light, even score all the way around the bottle.
Apply firm, even pressure all the way around, but don’t press down too hard. You might want to press down on the cutter, but this really isn’t necessary.
Make sure you only cut exactly once around – repeat passes are not helpful can make it more likely the bottle will crack instead of cut! Your glass cutter should have more detailed instructions on its operation.
3. Bring your pot or kettle of water to a boil and then remove it from the heat. You don’t want to pour boiling water on the bottle or it may crack unevenly, or even shatter! You can also pull the water before it’s quite boiling instead of letting it sit to cool down.
4. Put on your eye protection (seriously, please don’t skip this part!) and carefully pour a slow, steady stream of hot water onto your score mark while turning the bottle.
If your pot is too unwieldy, carefully dip a Pyrex measuring cup into the water to dip some out and use that, instead. Keep pouring water, slowly rotating the bottle, this until you notice the bottle becoming warm in your hand.
5. Immediately run the bottle under ‘cold’ water from the faucet. This water doesn’t need to be actually cold – ice water can shock the glass too badly. Just use the regular, not heated tap on your faucet.
You should notice the score mark is easier to see, thicker, and probably somewhat white. You may even start to hear a crackling noise!
6. Repeat the hot water/cold water process another two or three times, or until the bottle cracks open along the line. If it hasn’t separated after three tries or so, go ahead and bring out the ice water bath.
7. Be very careful when you handle the freshly-cut bottle pieces! They are extremely sharp and can cut you badly.
To dull the edges, sand them carefully in a shallow dish filled with water or under running water. To purchase a glass cutter visit Banggood.com
