You score it, you break it, and then you see those annoying little &ldquo;chip-outs&rdquo; or jagged edges—usually right at the corners where you least want them. The secret to fixing this? Heat. Specifically, infrared (IR) preheating before the cut.</p> <h2 id="how-it-actually-works">How it actually works</h2> <p>When glass is cold, it&rsquo;s tense. When the cutting wheel hits it, the surrounding cold material fights back. That struggle is what causes the crack to wander, leaving you with a messy edge. By hitting the glass with shortwave IR lamps, we warm up the surface. We aren&rsquo;t trying to melt anything here. We just want to relax the material enough so the crack can <a href="https://goldisgood.com">travel</a> in a straight, clean line. It feels different. The break is smoother. You aren&rsquo;t fighting the material anymore because the thermal energy handles a lot of that mechanical shock for you.</p>
