Stop Your Glass From Cracking: A Real-World Guide to Annealing

If you’ve ever seen a piece of glass shatter the second it hits the heat, you know that feeling. It’s frustrating. It’s a waste of material. And usually, it happens because the temperature jump was just too aggressive. When the outside of the glass expands way faster than the inside, it gives up. That’s thermal shock. To stop it, we use shortwave infrared (IR) lamps. The secret isn’t just the heat—it’s how fast you can control it.

Stop the Cracks: Getting Your Glass Annealing Right

There is nothing worse than spending hours on a batch of borosilicate glassware only to have it shatter for no apparent reason. Usually, it’s because the internal stress didn’t get neutralized. If your oven swings by just a few degrees, you’re playing a dangerous game with your equipment. That’s why we use high-precision infrared elements. We keep the temperature window within 0.1°C. It sounds like a tiny number, but it’s the difference between a perfect piece of lab glass and a pile of expensive shards.
