Glass cutting is the process of scoring and breaking glass to create specific shapes or sizes. It typically involves using a sharp tool called a glass cutter, which has a hardened wheel that scores the surface of the glass. Once scored, the glass can be snapped along the line, allowing for clean edges. This technique is commonly used in various applications, including window installation, art glass projects, and glass repair. Proper safety measures, such as wearing gloves and goggles, are essential to prevent injuries, as glass shards can be sharp and dangerous.
