Most of the time, it&rsquo;s because of internal stress that never got sorted out. Here&rsquo;s the deal: if your heater swings by just a few degrees, you&rsquo;re playing a dangerous game. You risk stress fractures the moment that glass starts to cool. That&rsquo;s why we use high-precision infrared quartz tubes. We keep things <a href="https://o-yate.net">within</a> a tight 0.1°C tolerance. It ensures the glass hits that sweet spot for annealing without accidentally melting or warping.</p>
