How to Cut Glass in Half How to Cut Glass in Half
The process used to cut glass in half is quick and easy and requires just a little bit of practice. Glass is a beautiful but delicate material which requires great attention to safety when cutting.
Step 1: Wash and Mark
Wash and dry the surface of the glass. This will clear it of any debris which may impede the glass cutter. Use a tape measure to measure the glass and mark a point half-way across. Use the measurement to apply tape vertically down the center of the glass.
Step 2: Cut Glass
Place the glass cutter at the very edge of the glass on the corner of the tape. Slowly move the glass cutter down the taped line with a moderate amount of force. Place a large pencil beneath the glass to act as a roller once you have done this and press down on either side of the scored line. This will snap the glass in half.
Step 3: Tidy the Glass
Tidy the glass by taking a whetstone and sanding the edges of your cut. Remember to sand the edges of both cut pieces. You should now have two perfectly cut pieces of glass.
