This happens because the molecular structure of silicon carbide vibrates at the close to the same frequency as microwave radiation. The molecular vibration is what causes the object to heat up. This is what is actually cooking your food, water molecules also vibrate rapidly in microwave radiation. so to answer your questions the some ceramics could have either water in them or some molecule in the glaze/clay that has a little bit of silicon carbide or other material that vibrates close to microwave radiation.

The structural stress inside the mug will continue till the crack goes all the way through. Contact your fraternity and order a new one (or two if you use it daily.) Hairline cracks can harbor lots of bacteria and you can never keep it clean. Give your old one a proper burial, it's served its time. You can repair it but it will never be the same.
