Usually, it&rsquo;s because of internal stress that didn&rsquo;t get neutralized. Here&rsquo;s the thing: if your heating element swings by even a couple of degrees, you&rsquo;re playing a dangerous game. You either end up with permanent stress patterns or a pile of shards during the cooling phase. That&rsquo;s why we use high-precision infrared lamps in our annealing lehrs. We aim for a tight 0.1°C tolerance. It <a href="https://goldisgood.com">keeps</a> the glass right at the annealing point without overshooting. It&rsquo;s about peace of mind.</p>
