There are many, many, many, many, many types of plastic. Saying "plastic bowls absorb fat" is misleading, in that it depends on what kind of plastic you have. Some are softer and more prous than others, and so unsuitable. But you cannot rule out "all plastic" or "all ceramic" any more than you can say "every dog likes to play fetch." Tupperware, for example, is a fairly soft plastic - if you store spaghetti sauce in it, it will stain. That is not true of harder plastics. Think about it.

For ceramics, if it is made in the U.S., and if it is people-safe, it is perfectly safe and fine, even if it has pretty colors. There are manufacturing standards set for such things.
