Common Mistakes to Avoid

1. Using Dull or Improper Scoring Tool

Reason: A dull scoring tool won't create a clean, deep enough score line, leading to uneven breaks and potentially dangerous jagged edges.
Solution: Use a sharp glass cutter or carbide scoring tool and ensure a firm, consistent score.

2. Applying Uneven Pressure During the Break

Reason: Inconsistent pressure during the breaking process can result in a shattered bottle instead of a clean break along the score line.
Solution: Apply even, controlled pressure along the scored line, using a smooth, consistent motion.
