Stop Wasting Power on Your Glass Annealing

Let’s be honest: glass annealing is an energy hog. Most traditional ovens are basically giant heat sponges—they waste a ton of power just heating up the air in the chamber before the glass even feels it. We do things differently. Instead of warming up the room, we use shortwave infrared (IR) lamps to hit the glass directly. It’s a much smarter way to work. You get faster ramp-up times and a electricity bill that doesn’t make you cringe at the end of the year. Getting the heat exactly where it needs to be If you want to hit those annealing temps without taking up half your factory floor, you need power that’s concentrated. Our lamps are built to push radiant energy deep into the glass surface. This means you can keep the temperature steady across the whole sheet. And because the lamps react almost instantly, you can tweak the heat on the fly as the glass moves down the line. No more guessing. Tough gear that actually fits We use high-purity quartz tubes because they can handle the shock of rapid heating and cooling without cracking. Depending on what kind of glass you’re running, we can coat the lamps to make sure the heat actually sinks in rather than bouncing off the surface. Plus, we use standard connectors. You can just swap them into your current setup without having to rip out your control panel and start from scratch. The honest truth about the trade-off Here’s the thing: shortwave IR packs a punch. It’s aggressive. While that’s great for your energy costs, it puts a lot of stress on the lamp housing. You can’t just ignore the “heat soak.” If your fans or vents aren’t up to the task, you’re going to fry your wiring or kill your lamps way too early. And a quick tip? Keep your reflectors clean. Dust is the enemy here. A dirty mirror kills your efficiency, so keep them sparkling and your lamps will keep performing.

Fixing Those Annoying Cold Spots in Glass Annealing

Ever deal with those frustrating “dead zones” when annealing glass? It usually happens with the tricky stuff—pieces with narrow necks or deep bases. You think the kiln is doing its job, but these cold spots linger, creating internal stress that eventually leads to a crack. It’s a nightmare. To fix this, we stop relying on the air. Instead, we use short-wave infrared (IR) lamps. Think of it as beaming heat directly into the glass rather than waiting for the air to warm up and drift around.
