You can&rsquo;t exactly fit a massive industrial oven in a repair shop. That&rsquo;s why we use shortwave infrared (IR) lamps. Instead of wasting time heating up all the air in the room, these lamps shoot thermal energy straight into the glass. It&rsquo;s direct. It&rsquo;s fast.</p> <h2 id="the-power-struggle">The Power Struggle</h2> <p>Here&rsquo;s the thing about portable rigs: you can&rsquo;t just keep cranking up the wattage. You&rsquo;ll fry something. Instead, we focus on<strong>power density</strong>. We use high-wattage quartz halogen tubes but keep them small. This concentrates the heat right where it needs to be, so the glass hits that softening point quickly. But be careful with your power supply. If your voltage is limited, you&rsquo;ve got to play around with the filament length and diameter. Otherwise, you&rsquo;re just going to keep tripping your circuit breakers.</p> http://ir-heat-ray.com/en/posts/uniform-heating-for-tempered-glass/ Sat, 11 Jul 2026 10:34:08 +0800 http://ir-heat-ray.com/en/posts/uniform-heating-for-tempered-glass/ <p><img src="http://ir-heat-ray.com/images/c147974466f1761700b8a23cd6bc5910.png" alt="Uniform heating for tempered glass"></p> <h1 id="fixing-those-pesky-cold-spots-in-glass-annealing">Fixing Those Pesky Cold Spots in Glass Annealing</h1> <p>If you&rsquo;ve ever worked with glassware kilns, you know the frustration of &ldquo;dead zones.&rdquo; It&rsquo;s a nightmare. You think the whole piece is heating up, but then you find out the narrow necks or weird corners never actually hit the right temperature. The problem is that standard convection heating is kind of lazy. Air just doesn&rsquo;t like to squeeze into tight gaps. That’s where shortwave infrared (IR) lamps come in. Instead of hoping the air carries the heat, IR radiation just shoots straight through. It hits the glass directly, making sure the core of the vessel actually gets hot enough to soak properly. No more guessing games.</p>
