You may wish to make decorative, free-form cuts in a mirror for some artistic project, or you may simply need to cut one down so it fits on your wall. Whatever the reason, you'll be happy to know just how easy it is to do. For most home projects, there's no need for a professional glazier; just the right tools, the proper technique and a little self-confidence.
Things You'll Need
- Rubbing alcohol
- Small towel
- Large towel
- Contact paper
- Masking tape
- Lubricating oil
- Glass cutter
- Straight edge
- Garbage can
Put on safety gloves and goggles.
Clean the mirror of any debris with rubbing alcohol and a lint-free towel, especially at the point where you will score and cut it. Even a speck of dirt along the score line can cause the mirror to break in ways you didn't intend.
Lay out a terrycloth towel on a perfectly flat surface to protect the backing of the mirror and to prevent the score line from running. To be extra cautious, you can cover the back of the mirror with contact paper.
Draw your cut line with a washable glass marker, using a straight edge as a guide.
Lay thick masking tape along the line to make it clear and to give a guiding ledge to your cutter, as it can be hard to distinguish the cut line from its reflection in the mirror.
Lubricate your glass cutter with oil.
Score the glass with the glass cutter, keeping the glass on the towel. Use consistent pressure that is just firm enough to make a thin visible scratch. Keep the wheel perpendicular to the glass.
Break the mirror at the score line over a large-mouthed garbage.
