You pull them out of the lehr, everything looks fine, and then—<em>pop</em>. They shatter for no apparent reason. The <a href="https://o-yate.com">problem</a> is &ldquo;dead zones.&rdquo; In a standard oven, the heat just doesn&rsquo;t get into the tight spots. Those narrow necks and deep bases stay too cool, leaving internal stress trapped in the glass. It&rsquo;s a ticking time bomb. We&rsquo;ve found a way to stop this. Instead of just cranking up the bulk heat and hoping for the best, we use targeted infrared (IR) lamp arrays.</p>
