There is a lot of confusion and misunderstanding when it comes to how to cut glass. Glass is easy to cut but the real challenge is getting the perfect angle. With a little practice, it really isn’t that hard. If you’re ever unsure about how to cut glass, get a glass cutter.
First off, here’s a helpful tip. When learning how to cut some glass, I always try to get the measurements right first off. I always start at the bottom and measure across to the top. There are other more advanced and convoluted ways to cut glass bottles with no measuring and using just a straight line, but you don’t have to be placing anything in the oven, blowingtorch anything, heating foil, wire or melting anything else. There are some nice resources for making a straight line, even if you don’t want to cut glass.
Here’s a helpful note: if you want to cut a nice smooth flat edge, use sandpaper and go over everything with a fine tooth until you get the best results you can. There are some edges that are easier to deal with than others, but this is something that will come with experience. Now that you have all that sandpaper back, what you need to do is simply wet sand the whole surface, starting from one corner and running it over to the other. If you want to create a more severe custom cut, try doing it on a vertical or horizontal cut. This will give you a much more unique design.
There are two important things to remember with how to cut glass bottles. The first is to make sure that you don’t go over the edges because you’ll probably ruin the image you’re trying to create. The second thing to keep in mind is to make sure that the edges of your bottles are all uniform. You don’t want a bottle of wine with uneven edges, and you don’t want to have a bottleneck with uneven top edges either. You’ll get the best results when all of the edges are uniform, as opposed to an edge that’s off center because one of the edges was off center.
Once you’ve made sure all of your edges are uniform and all of your bottles are the same size, you can start practicing how to cut glass bottles. The best way to do this is actually practiced and not just do it in your room. Get a few bottles of wine and put them in a vise to make sure that you can cut them correctly. Once you can handle this on your own, you should take some classes. Whether you take a class online or at your local community college, taking a course will show other people your true craftsmanship and will serve as an example to other people who might be interested in taking up bottle cutting.
The final step in learning how to cut glass is to score the glass. Score it at an angle so that the score makes a clean line. Score it straight if you’re using a real stained glass cutter, but if you’re using a cheap glass cutter, just score it at an angle so that it cuts a straight line. Use your score to smooth out any bubbles and to test for alignment. Using the score to score your glass gives you the opportunity to have more control over the end product, but if you’re not experienced at this, it’s better to score it flat. This will ensure that the glass is cut as smooth as possible and will give you the ability to create unique stained glass designs on the resulting bottle.
