It happens. When thermal gradients get too steep, the glass just gives up. The problem is that most bending furnaces are cramped. They aren&rsquo;t designed with much breathing room. If you try to shove a standard, off-the-shelf infrared lamp into those tight gaps, it usually doesn&rsquo;t fit. Or worse, it fits, but it leaves &ldquo;cold spots&rdquo; that ruin your work.</p>
