You’re in the middle of a run, maybe there&rsquo;s a slight temperature spike or you bump it against the bench, and <em>crack</em>. It’s frustrating. But <a href="https://henruite.com">usually</a>, the problem didn&rsquo;t start in the lab—it started during manufacturing. When glass cools too fast or unevenly, it traps microscopic tension inside the walls. We call these internal stresses, and they&rsquo;re basically ticking time bombs. To stop this, we use continuous annealing heaters with infrared (IR) elements to let the glass relax properly.</p>
