When I mounted the over stove microwave last week, I had to remove the contents of the cabinets so I could drill for the bolts which support from the top.
In the cabinet was a large ceramic bowl, with 6 dessert plates if you will.
Awesome, we actually could use those plates. Washed the bowl and plates.
I heard a strange pinging sound coming from the bowl. Baffling, almost like in the old days when you had a car and shut it off, you could hear the exhaust and catalytic converter contracting.
My wife since put fruit in the bowl and set it on the dining room table.
It's still pinging now!
Since google is my friend, it's called crazing and involves defects in the glazing process. It defies common sense imho....

The other day our ecobee remote temp sensor registered movement in the basement in the middle of the night. These sensors measure temp and have motion detection capability.
I checked with other household members who claim not to have gone down to the basement. Very strange...

I might add that early on in our first microwave/convection oven combo unit, we experienced some crazing in some ceramic stuff stored over the unit. They were items that were not microwave safe or oven proof. The maker of the unit told us not to store items over the unit unless they were microwave safe or oven proof. I was told that very fine cracks develop in the items from excursions in heat and once the cracks develop it is all downhill from there. And don’t use those items in a microwave cycle. Moisture will get into those cracks hastening the process. A microwave generates heat by causing water molecules in food to vibrate, producing heat that cooks the food.
I might add that when I run the convection over for an extended period, perhaps 45 minutes, everything above the unit is warm to the touch.

Wow!
Learn something everyday. My girlfriend has a souvenir from a famous hotel that is quite old with those cracks. Couldn't explain what that was until now. I just knew it was old. Never knew it was called crazing. How crazy!

They'd have to be really big mice. The sensor is placed at least 6' off the ground, and slightly angled up.
Specs say
angle: 140° horizontal, 100° vertical
range: 20 ft (6 m)
We're in the basement (finished) quite often, if there we mice, there'd be droppings and other evidence.
