    It’s the many tiny air bubbles trapped in low quality ceramics that vibrate and heat it up.

      Possibly, feldspar content can have an effect as well in ceramic but in general the plate is not doing the heating or being heated. An ideal ceramic plate or plastic plate doesn’t heat until you get real crazy and manage to hit a frequency it likes.
