How to Safely Cut Glass to Size

Cutting Glass To Size

There are few things more frustrating than putting together a beautiful glass project and then having it suddenly break at a completely different angle to what you had intended. This often happens when you are trying to cut your own glass for a picture frame or to replace a broken window pane in your home. It can also happen when you are working on a glass project for work, like a new storefront or lobby. It is essential that you follow the correct steps to avoid this frustration and ensure the safety of yourself, your family and others who may come into contact with your creation.

Whether you are replacing a single pane in a window or completing an entire glass fabrication job, there is a simple formula that can help make the process smoother and safer. Start with the measurements of your opening and then use our glass size calculator to determine the precise dimensions you will need for the replacement pane. Once you have the precise size, take the measurements to your local hardware store and ask them to cut the glass to this exact size. This is a free service and can save you a lot of time and hassle.

When working with glass, you need to keep the following guidelines in mind to make your task easier and safer. Glass leaves tiny particles of powder when it is cut, so you should put down a thick cloth on your table or work surface before you begin. Also, glass does not always break cleanly, so you should also put on some gloves and a pair of goggles.

It is important to score the glass in a place that will give you an even amount of material on either side of your line. This will help you to prevent the glass from flaring out at the edges as it is broken and will result in a more consistent, clean break.

Once you have scored your piece of glass, you should hold it with a pair of pliers that are specifically made for cutting and breaking glass. These are usually called cut-running pliers and can be purchased from any stained glass supplier. These pliers are very helpful when you are scoring curves or doing large pieces, and they will also help to prevent the break from becoming uneven or jagged.

When you are ready to break your glass, hold the cutter firmly in one hand, allowing the ring finger of your other hand to rest on the straight edge ruler. Then slowly pull the cutter towards you and apply moderate pressure. Keep the guiding hand on the straight edge ruler firmly so that it does not slip, and remember to stay clear of the cutter head for your own safety. If you are unable to achieve uniformed score lines, you should consider changing the position of your body while cutting and try again. The more you practice, the better you will get.
