It’s the worst feeling. Usually, it happens because the internal stress didn&rsquo;t get neutralized. If your batch furnace swings by even a few degrees while you&rsquo;re soaking, you&rsquo;re basically gambling with stress fractures. That&rsquo;s why we use infrared heating elements. They give us 0.1°C precision, which keeps the glass exactly where it needs to be.</p>
