In the world of glass annealing, &ldquo;heat&rdquo; isn&rsquo;t the goal. The real goal is controlling how that glass cools down so it doesn&rsquo;t have any hidden internal stress. Get that temperature profile off by just a few degrees?**Crack.**There goes your product.</p> <h2 id="the-tricky-part-about-ir-heat">The tricky part about IR heat</h2> <p>We use short-wave infrared lamps because they punch through glass way faster than just blowing hot air around. But here&rsquo;s the thing: heat density changes based on your wattage and voltage. A high-wattage tube puts out a massive amount of heat. If your conveyor belt isn&rsquo;t moving at the exact right speed to match that output, you&rsquo;ll end up with hot spots. You can&rsquo;t just swap a bulb and expect a systemic thermal mess to magically fix itself.</p>
