Dealing with “Cold Spots” in Long Glass Tunnel Kilns

Most infrared lamps stop at 1.5 meters. If you’re running a long tunnel kiln, that’s a problem. Why? Because every time you hit a joint between two lamps, you get a cold spot. In the glass world, a cold spot is a recipe for disaster. That’s why we build custom quartz heaters that push past the 2-meter mark. We design them specifically for those long, continuous linear arrays where you just can’t afford a dip in temperature. The struggle with power and voltage You can’t just stretch a filament and call it a day. It doesn’t work like that. The longer the filament, the higher the electrical resistance. If you aren’t careful, the ends of your lamp will be lukewarm while the center is screaming hot. We spend a lot of time tweaking the voltage and wattage to keep things balanced. We’re basically fighting the ohms to make sure the heat stays flat and consistent from end to end. Just a heads-up: you’ll want to double-check your power supply. These custom loads can be heavy, and nobody likes a tripped breaker in the middle of a run. Keeping things steady We use high-purity quartz because it can take the thermal shock of a tunnel kiln without flinching. But there’s a catch. When a heater gets this long, it wants to sag. If that filament shifts even a little, you get a hot spot. And a hot spot means cracked glass. To stop that, we beef up the internal supports to keep everything centered. We also offer a few different end-cap options so the units slide right in without putting any weird stress on the quartz tube. A few things to watch for during install Wiring these arrays takes a bit of a steady hand. We use industrial connectors because they actually stay tight, which means you won’t have to worry about arcing when the current kicks in. One last thing. When you pack 2-meter heaters into a tight space, the ambient heat builds up fast. It gets hot. Make sure your cooling system can actually handle that load. If it can’t, you’re just cooking your own sockets and wiring harnesses, and that’s a headache you don’t need.

Heat treatment for quartz glass

Cutting through ultra-thick glass is basically a wrestling match with the material. If you’ve ever tried to run a cutting wheel through thick quartz or soda-lime glass, you know the feeling. The stress on that blade is brutal. You end up with chipped edges and a pile of dead tools that need replacing way too often. We found a better way. Instead of just forcing the blade through, we use shortwave infrared (IR) lamps to soften the glass right where the cut happens. Here is why that matters. Most heaters just warm up the surface, which doesn’t do much for a thick slab. Shortwave IR is different. It actually sinks deep into the glass rather than just bouncing off the top. By hitting the cutting path with this heat, we drop the viscosity of the glass. Essentially, we’re making the glass “give” a little. It means the wheel doesn’t have to fight nearly as hard to leave a clean score line. To get this right, we use high-wattage quartz halogen lamps. The trick is all about power density. You want a sharp, hot spike exactly where the blade meets the glass. If the heat spreads too much, you’re asking for trouble—things like warping or thermal shock. That’s why we keep the lamps in a tight array, focusing all that energy on one spot. Now, there’s a trade-off. Your cutting wheels will last way longer because you aren’t slamming a cold blade into a rigid crystal lattice. But these lamps put out a massive amount of heat. If your cooling system isn’t up to the task, you’ll fry your wiring or melt your sockets. It’s a balancing act: you need enough heat to soften the glass, but you have to keep the movement speed precise so you don’t overheat the whole piece. My advice? Wire those lamps into a fast-response PID controller. It keeps everything in the sweet spot—soft enough for the blade to glide through, but not so hot that the glass cracks when it cools down.

No More Rewiring: Just Swap Your IR Tubes and Get Back to Work

Look, when an infrared lamp burns out in the middle of a production run, the last thing you want to do is spend your afternoon fabricating new brackets or messing with the wiring. You just want the machine running again. That’s why we make our clear quartz tubes a “drop-in” fit. No hacks, no modifications, no headaches.

The struggle with the fit

Here is the thing: IR systems are a mess of different connectors. You’ve got spiral ends, R7s, and those weird custom shapes that seem to exist just to make your life harder. If the fit is off by even a tiny bit, you’re looking at poor electrical contact or, worse, putting too much stress on the glass. That’s a recipe for a break. We build our tubes to match those exact shapes. Whether it’s a standard screw-in or some proprietary clip, it just slides right into the socket. Your machine frame stays exactly as it is.

Stopping the Crack: How to Handle Glass Tempering Without the Heartbreak

Anyone who’s worked with quartz tubes knows that sinking feeling. You’ve spent all that time shaping a piece, only for it to snap the second it hits the cooling phase. It’s frustrating. Most of the time, it comes down to thermal shock—the temperature just drops too fast for the glass to keep up. That’s why we use shortwave IR lamps. They let us do what I call “instant tempering.” Instead of guessing, we can tweak the heat on the fly to keep the glass happy.
