You&rsquo;ve got this wide, open bowl on one end and a skinny little stem on the other. The problem is that heat just doesn&rsquo;t like to move evenly across those shapes. You end up with &ldquo;cold spots.&rdquo; While the bowl is sitting pretty at the right temperature, the stem is lagging behind. That temperature gap creates internal stress, and before you know it, your glass is cracking. It&rsquo;s frustrating. To fix this, we stopped relying on standard convection or resistance heating. Instead, we started using targeted short-wave <a href="https://o-yate.com">infrared</a> (IR) arrays.</p>
