If that glass cools unevenly, you get internal stress. Then, it cracks. It&rsquo;s a nightmare. That&rsquo;s why we lean on short-wave <a href="https://goldisgood.com">infrared</a> (IR) lamps for inline annealing. They hit the target temperature almost instantly. No waiting around.</p> <h2 id="the-problem-with-lag">The problem with &ldquo;lag&rdquo;</h2> <p>Old-school ovens are slow. They take forever to heat up and even longer to cool down. That lag is a production killer. Our IR lamps use a tungsten filament inside a quartz envelope. The radiation actually penetrates the glass surface rather than just sitting on top of it. This means you can tweak your heat profile on the fly while the glass is still moving on the conveyor. You get exactly the temperature you need without having to kill the line.</p>
