Serious question, did my latest vase just attempt a solo escape from the annealer because of a temperature hiccup?

Wait, what?! Your vase tried to make a break for it? That's wild. I've heard of thermal stress causing cracks, but a full-on jailbreak from the annealer is next level. How bad was the temperature swing to make it shift like that? You gotta share a picture if it's still in one piece, that sounds like a story.

Did the temperature SWING that violently? I've never heard of glass actually MOVING in the annealer!

During a frost warning in Toledo, our annealer dropped 40 degrees overnight. That caused a heavy vase to shift and crack against the door (a real mess to clean up, honestly). It's rare, but rapid cooling can make glass contract unevenly and actually move, especially with thicker pieces. I've seen it happen when the kiln cools too fast in a drafty room. Always monitor ambient temperature, since even stable settings can be fooled by a cold snap.
