One wrong move with your thermal gradients and you&rsquo;ve got cracks. It&rsquo;s a headache. When you&rsquo;re running an ultra-long tunnel kiln, standard lamps just don&rsquo;t do the job. They&rsquo;re too short. We&rsquo;ve found that the real secret is using custom infrared units that stretch over 2 meters. Why? Because it kills the gaps. Fewer gaps mean a much smoother ride for the glass.</p>
