You&rsquo;re staring at those stress patterns and wondering why some sheets come out perfect while others just&hellip; snap. Or worse, they warp while they&rsquo;re cooling. It’s a nightmare. Most of the time, it comes down to one thing: your heat isn&rsquo;t hitting the glass evenly.</p> <h2 id="the-problem-with-standard-heat">The problem with &ldquo;standard&rdquo; heat</h2> <p>Here is the thing about IR lamps. Most shops just throw in <a href="https://o-yate.net">standard</a> ones, but they aren&rsquo;t all created equal. Think about it. If one lamp is pushing 1200W and the one right next to it is only doing 1100W, you&rsquo;ve just baked a temperature gradient right into your workpiece. The glass expands differently in different spots, and that&rsquo;s where the trouble starts. We handle this by obsessing over the small stuff—the quartz purity and the filament density. We make sure the wattage doesn&rsquo;t drift between units. The goal is simple: every single square inch of that glass needs to hit the target temperature at the exact same time. No hot spots, no cold gaps.</p>
