Between the safety additives, the thermal insulation, and the UV protection, the chemistry is complex. Here is the problem: those additives change how the glass reacts to heat. If your IR lamps are pumping out wavelengths the glass just doesn&rsquo;t &ldquo;like,&rdquo; the energy doesn&rsquo;t soak in. It just bounces off the surface. You&rsquo;re paying for the electricity, but the glass isn&rsquo;t getting warm. That&rsquo;s how you end up with uneven heating and a lot of frustration.</p>
