A few days ago, I slid a glass plate of leftover pasta into the microwave, pressed the buttons, and waited. Moments later, a sharp crack emanated from the microwave. I opened the door to find a fractured plate, cradling hot pasta like a messy broken mosaic. And I found myself wondering, “Why did the glass in the plate shatter, especially as it was on the unaffected glass rotating base of the microwave?”
I also know that the melting point of glass is around 1,400°C, which is very much higher than any temperature possible in a microwave oven, or even a conventional oven.
