You&rsquo;ve got that wide bowl on one end and a skinny little stem on the other. In a standard annealing lehr, that shape creates &ldquo;dead zones&rdquo;—spots where the heat just doesn&rsquo;t reach. If the rim is roasting but the stem stays cool, you get internal stress in the glass. And that&rsquo;s how you end up with glasses that just&hellip; snap. Out of nowhere. To stop that, we use targeted infrared (IR) lamps to plug those gaps.</p>
