Scoring

Scoring

Overview

Scoring is the technique of creating a controlled scratch or groove on a sheet of glass using a scoring wheel or similar tool. This scratch forms a weak line along which the glass can be cleanly broken. Scoring is essential in picture framing, glazing, and glass fabrication when resizing or shaping glass panels.

Uses in Framing

• Resizing glass to fit custom picture frames or mat openings.
• Trimming specialty glazing materials, such as Tru Vue Glass.
• Creating straight, precise edges for professional framing and display.
• Preparing glass for safe handling and installation in frames, shadow boxes, or display cases.

Best Practices

• Use a high-quality Glass Cutter with a sharp wheel for consistent scoring.
• Apply even pressure along the scoring line to avoid irregular breaks.
• Support the glass firmly while scoring and snapping to prevent uncontrolled cracking.
• Wear protective gloves and eye protection to minimize risk of injury.
• Clean the glass surface to remove dust, debris, or oils before scoring.
