If you’re looking for another source to buy uncut mirror, look for specialty shops that deal specifically in mirror and glass. It may be helpful to purchase a few pieces of inexpensive mirror to practice on. Try single-strength window glass, since it is easier to cut and usually the least expensive.
Use another microfiber cloth to wipe the surface down once more to ensure the mirror is completely dry before you begin.
Avoid wearing open-toed shoes or sandals. If you end up with a glass splinter, try to remove it by placing a sticky piece of tape over it and then whipping it off quickly. If that doesn’t work, use tweezers.
Look for scoring tools that have a sturdy design and a true carbide wheel. The cheaper tools can cost as little as five dollars. Those of higher quality are usually closer to twenty. You can get glass scoring tools at craft shops and hardware stores. Hardware stores usually carry the more expensive, sturdier models.
If you have a very small job to do, look for a steel-wheel cutter. They work as well as the carbide wheels, and are even cheaper. If you are looking to cut a lot of mirror, invest in the self-oiling mirror cutter. It can last longer than other cutters, and is usually easier to use.
The cleanest break lines will be created when you score with one continuous motion of the tool. [5] X Research source Always mark your score lines starting at one edge of the glass and ending at the other. [6] X Research source
You can run the scoring tool along the line toward you or away from you. Try both ways to find out which you feel most comfortable with. [7] X Research source If you’re concerned that your straight edge might wiggle around while you’re scoring, try using a simple clamp to hold it firmly in place. [8] X Research source
Try to apply an equal amount of pressure for the duration of the score. [9] X Research source Avoid lifting your tool up during the process so that you can score the line in one continuous motion. [10] X Research source
For best results, try to keep your work space as debris-free as possible throughout the process.
Quickly make a snapping motion with your wrists and the mirror should break crisply along the score line. Always wear protective gloves when you’re breaking glass. The score lines render the glass unstable and sometimes it can shatter in ways you aren’t expecting.
If you’re breaking a long score line, you might want to apply the pliers gently at one end, until you hear a very faint clicking sound. Then turn the mirror around and do the same thing on the other end of the line. This will cleanly complete the break at the edges.
