But here&rsquo;s the thing: if your IR lamps are off by even 5% across the heating bank, you&rsquo;ve got a problem. You get these thermal gradients—basically, some spots are hotter than others. That creates internal stress in the glass. And that&rsquo;s how you end up with cracks or, even worse, an entire batch shattering. We see it all the time. A few mismatched lamps create &ldquo;cold spots&rdquo; in the oven, and suddenly your yield tanks.</p>
