One tiny bit of internal stress in your quartz or borosilicate, and—<em>pop</em>—the whole thing shatters. It&rsquo;s frustrating and expensive. To stop that from happening, we use infrared (IR) heating elements tucked inside quartz sleeves. The whole <a href="https://o-yate.net">point</a> is to hit that perfect annealing temperature and then let the glass cool down slowly. You want the molecular structure to relax without creating new temperature gaps that could lead to a crack.</p>
