Stop Wasting Power on Your Glass Annealing

Let’s be honest: annealing is usually the biggest power hog in the entire shop. Most of us are still using old-school heating systems that basically just warm up the air around the glass, wasting a ton of energy before the glass even feels a thing. We do things differently with shortwave infrared (IR) lamps. The secret is in how the heat moves. Standard heaters rely on convection—they heat the air, and the air heats the glass. It’s slow. Shortwave IR is different. It uses radiation to hit the glass surface directly. It’s fast. Really fast. Because you aren’t wasting time heating up the entire volume of the oven, you don’t have that massive idle power draw dragging down your margins. But you can’t just slap a new bulb in and call it a day. To actually see your electric bill drop, you’ve got to get the wattage and wavelength exactly right for the thickness of your glass. We design these lamps to hit the specific spots where glass actually absorbs heat. And then there’s the spacing. This is where people usually mess up. If the lamps are too close, you’ll get “hot spots” that can cause thermal shock and crack your work. Too far away, and you’re right back to wasting energy. It’s all about that sweet spot. What this looks like on the shop floor. Switching to IR is great for your overhead, but it does put more pressure on your controls. These lamps react instantly. Unlike those old resistive coils that stay hot for minutes after you turn them off, IR kills the heat the second you flip the switch. Because of that, you’ll need precise PID controllers. If you don’t, you’ll overshoot your temperature every time. One last thing: check your wiring before you start. High-wattage IR arrays pull a lot of current when they first kick on. Make sure your panels can handle the load, or you’ll be spending your afternoon replacing blown breakers.
