Then the headaches show up—edge cracks after quench, wavy distortion, or optical marks that fail inspection. Most of the time, the culprit isn’t peak temperature. It’s uneven heat across the glass surface. Tempering is all about controlled stress. If the thermal field is off, the glass doesn’t expand uniformly before quench. You get localized stress peaks, warped geometry, and optical anomalies that scream under polarized light. In production, that translates to scrap, rework, and a furnace that never settles. We built our approach around one objective: keep temperature consistent across the entire load, edge to edge, corner to corner.</p>
