Title: Why do blue ceramics get hotter in the microwave?
Post by: evan_au on 03/04/2014 20:37:37
When I place a blue ceramic mug or blue ceramic bowl in the microwave, the ceramic seems to heat up hotter than other colours - and the food/drink inside seems to heat up less. Why is it so?

I don't think I've noticed it, but is it possible that Cobalt Blue (http://en.wikipedia.org/wiki/Cobalt_blue) which contains cobalt and aluminum oxides would be reactive in the microwave?
