It doesn&rsquo;t actually solve the problem. When you&rsquo;re messing around with new glass materials, the real battle is the thermal gradient across that roller. If that&rsquo;s off, your final product is off. That&rsquo;s why we stop talking about &ldquo;total wattage&rdquo; and start talking about<strong>power density</strong>. It&rsquo;s all about controlling exactly where the heat lands on the glass.</p>
