You&rsquo;re using standard convection heating, but the heat just can&rsquo;t seem to find its way into those tight curves or deep pockets of the vessel. The result? Uneven stress. And we all know where that leads—shattered glass and a lot of wasted time. To fix this, we stop relying on the air to do the heavy lifting. Instead, we bring in short-wave infrared (IR) heating lamps. They hit the material directly, so it doesn&rsquo;t matter if there&rsquo;s an air gap in the way.</p>
