The <a href="https://o-yate.net">problem</a> is that standard convection or resistive heating just can&rsquo;t get into the tight nooks and crannies of a complex shape. They essentially &ldquo;miss&rdquo; the hardest parts. We’ve found that the best way to handle this is with quartz infrared (IR) lamps. Instead of hoping the air carries the heat, we use direct radiative transfer.</p>
