You score it, you break it, and you just hope you don&rsquo;t end up with those annoying jagged edges or a corner that snaps off right where it shouldn&rsquo;t. It&rsquo;s frustrating, and it wastes material. The trick to stopping this is simple: don&rsquo;t cut it cold. We use infrared preheating to prep the glass before the blade ever touches it.</p> <h2 id="the-why-behind-the-heat">The &ldquo;Why&rdquo; Behind the Heat</h2> <p>Glass is stubborn and brittle. When you hit it with a cold blade, the internal tension is high, and the crack can jump or branch out in directions you didn&rsquo;t intend. That&rsquo;s where those chips come from. By running shortwave infrared lamps over the cutting line, we soften things up. It&rsquo;s not about melting the glass, but just easing those molecular bonds. This lets the crack glide cleanly along the score line. No jumping, no branching, just a smooth edge.</p>
