It’s frustrating, it’s expensive, and it usually happens right when you think you’ve got the process dialed in. The culprit? Thermal gradients. Basically, when one part of your glass is way hotter than the part right next to it, the tension builds up until the piece just gives way. In a tight, non-standard bending furnace, this is a nightmare. If your heating elements don&rsquo;t hug the curve or fit into those awkward narrow gaps, you end up with cold spots. And cold spots are where the cracks start.</p>
