Why Your IR Lamps Are Probably Ruining Your Glass

Ever wonder why one batch of glass bulbs comes out perfect, but the next one is a disaster? You didn’t change the timer. You didn’t change the glass. But there they are—cracking during cooling or failing pressure tests. It usually comes down to “cold spots.” Here’s the thing: if your infrared lamps aren’t pushing out the exact same amount of heat, your glass is feeling it. When one lamp is slightly weaker than the one next to it, you get uneven internal stress. That’s a recipe for failure.

Getting the Heat Right: Silk-Screen Tempering Without the Headaches

When you try to mix tempering with silk-screening, you’re basically fighting a tug-of-war. You need enough heat to make the ink stick and get the internal stress out of the glass. But if you go overboard—or if the heat hits unevenly—you’ll end up with burnt patterns or warped glass. It’s a delicate balance. To fix this, we use shortwave quartz halogen emitters. Think of these as high-energy bursts. They hit the surface fast and hard, which means you aren’t just soaking the entire piece of glass in heat for no reason.
