No impact, no obvious reason, just a sudden crack. It’s a nightmare. Usually, it happens because of internal thermal <a href="https://goldisgood.com">stress</a> that didn&rsquo;t get sorted out during the annealing process. That’s why we’re obsessed with 0.1℃ precision.</p> <h2 id="the-struggle-with-temperature-swings">The struggle with temperature swings</h2> <p>Most heaters are a bit clumsy. They overshoot the mark, then dip too low. In the world of high-end glass, a swing of just a few degrees is <a href="https://henruite.com">enough</a> to leave &ldquo;invisible&rdquo; stress in the walls of your vessel. We use infrared emitters and high-frequency PID control to keep the temperature in a tiny, tight window. It stops that &ldquo;thermal shock&rdquo; from happening. By sitting exactly at the annealing point, the molecular structure of the glass gets to relax and stabilize without the whole thing warping.</p>
