fun fact: water should react most strongly to the radiation used in microwaves while ceramic plates and glass should be pretty much inert - feel free to test by inserting first an empty mug of your choice, then doing the same wirh the mug filled with water and coming back to us with your findings :)
Here is a nice starting point for further reading
also as a side note: metals also react very strongly and the strong reaction of metals combined with the weak reaction of ceramic materials is why microwave kilns are a thing (for an explanation see the appropriate section here under "modern kilns")
Please note that some ceramics are porous, so they contain water. If you put them in the microwave empty, that water is going to heat up fast and expand. If the water can't get out fast enough, the cup will shatter.
So don't go doing this with your favorite cup and be prepared to give the microwave a proper clean. You don't want any small chips of ceramic in your food.
thanks for the disclaimer :)
Personal observation says it's coal (graphite, fats). Is this because of induced currents?
