We use infrared heating elements to manage the annealing point—the temperature where glass transitions from a plastic state to a rigid one. If your temperature swings by even a few degrees, you risk spontaneous stress fracture during cooling.</p> <h2 id="why-01c-precision-matters">Why 0.1°C Precision Matters</h2> <p>Standard heaters often overshoot their targets. In precision annealing, a 0.1°C tolerance isn&rsquo;t about luxury; it&rsquo;s about physics. We use high-frequency PID controllers paired with infrared emitters to maintain a tight thermal window. This prevents &ldquo;thermal shock,&rdquo; where the exterior of the glass bead cools faster than the core. When the Delta-T is too wide, the glass pulls against itself. It cracks.</p>
