The process for cutting glass follows these simple steps: Thoroughly clean the glass you intent to cut. Lay the glass on a clean, flat, layered surface. Measure the glass to the required dimensions. Score the glass with a glass cutter, using a straightedge for guidance. Snap the glass along the scored line. Smooth out any sharp edges.

Lay damp rag on a clean workbench, set glass on top. Clean glass with window cleaner. Measure and mark the glass for cutting. Use duct tape to secure straightedge to glass. Lubricate wheel on glass cutter with cutting oil. Guide glass cutter along straightedge in one continuous pass to score the glass. Peel up the tape and remove straightedge.
