Ceramic all the way. I have various matching sizes from tiny brulee for my hogs, to the small bowls for hatchling balls and subadults, to the huge ones for breeder balls and my super dwarfs. In all the time I've had them I haven't broken a single one. I chipped the bathtub once on accident by dropping a bowl while cleaning. Other then that, I wouldn't use anything else. I've never had a tip over since I started using them.

Regards,
