One batch comes out perfect, and the next is a nightmare of unpredictable breaks and internal stress. Usually, it comes down to one annoying thing: your heat isn&rsquo;t hitting the glass evenly. Think about your lamp array. If one lamp is putting out even 5% less energy than the one right next to it, you&rsquo;ve got a problem. You get these thermal gradients—basically hot and cold spots—that mess with the glass. That&rsquo;s where the stress builds up, and that&rsquo;s why things snap when they shouldn&rsquo;t.</p>
