Dumb question about microwaves

[Anonymous]

Forgive me, I managed to grow well into adulthood without really using a microwave. Now I do, and have a question. I have a set of dishes that are porcelain or ceramic that say they are microwave safe. When I use a bowl (or plate) to heat up food, after 2 minutes the bowl will be super hot and the food barely lukewarm.
I have some different bowls, also ceramic or porcelain, also say microwave safe. If I put the same food in those bowls and microwave for 2 minutes, the food is piping hot and the bowl is comfortable to touch.
Why the difference?is there some secret kind of dishes I should look for to use in the microwave, or ones I should avoid? The first dishes are made in Portugal, while the second say made in China, if that matters.

You do know that fat will cook faster and hotter in a microwave, right?

I find that is a bowl of cup is chipped or cracked, it gets insanely hot in the microwave. I guess it has something to do with the ceramic glaze spreading the heat around or something. But it’s really notable. I heat water for tea in ceramic mugs daily.

"The plate does not get as hot is that it is typically made of materials that are not very good at absorbing microwave radiation" .
