It’s a nightmare. You get these &ldquo;dead zones&rdquo; where the heat just won&rsquo;t go—usually in those narrow necks or deep recesses. Standard <a href="https://o-yate.net">convection</a> ovens are great for simple shapes, but they fail here because air just can&rsquo;t get into the tight spots. That&rsquo;s why we switched to short-wave infrared (IR) lamps. Instead of relying on hot air to drift around, IR radiation goes straight through the glass and heats the material from the inside out. It&rsquo;s a completely different ballgame.</p>
