When that cutting wheel hits the surface, it creates a tiny, high-stress point. If the glass is freezing, the fracture doesn&rsquo;t travel in a straight line. Instead, it jumps and jaggedly rips through the material. That&rsquo;s how you end up with those annoying chips or corner breakouts that ruin a perfectly good piece. To fix this, we use infrared (IR) preheating. It changes how the glass actually reacts to the blade.</p>
