It usually happens because the furnace swung by just a few degrees during the cooling phase. One tiny slip, and you&rsquo;ve got <a href="https://henruite.com">stress</a> fractures. That&rsquo;s why we use infrared heating elements that hit a 0.1°C precision. We need that glass to stay exactly at its annealing point. No guessing.</p>
