You look at a batch and realize the edges aren&rsquo;t cooling the same way the center is. Usually, it comes down to the lamps. If your infrared lamps are off by even 5% in wattage or spectral output, you get hot spots. That might not sound like much, but it’s enough to leave residual stress in the stem or make the bowl cool unevenly. The result? A mountain of scrap glass and a lot of wasted time.</p>
