When you score and snap it cold, the internal stresses often lead to &ldquo;chipping&rdquo; or &ldquo;blowouts&rdquo; at the edges. We use infrared (IR) preheating to fix this. By raising the glass surface temperature before the <a href="https://goldisgood.com">cutter</a> hits, you modify the material&rsquo;s mechanical response.</p> <h2 id="the-physics-of-preheating">The Physics of Preheating</h2> <p>Cold glass resists the cutter&rsquo;s diamond or carbide wheel, creating erratic micro-fractures. IR lamps penetrate the surface, inducing a controlled thermal expansion. This softens the glass structure just enough to ensure the score line is clean and consistent. We target a specific temperature window—usually between 60°C and 150°C depending on the thickness—to minimize the energy required for the break.</p>
