That’s &ldquo;chip-out,&rdquo; and it&rsquo;s a nightmare. The problem is that at room temperature, thick glass is just too brittle. When the cutting wheel digs in to make that score line, the internal stress is through the roof. Instead of a clean line, the crack wanders or just shatters wherever it feels like. That&rsquo;s where infrared (IR) preheating comes in. It basically relaxes the glass, lowering the surface tension so the material is more &ldquo;willing&rdquo; to be cut.</p>
