Desperately needing additional dishes in a hurry I ordered these, seeing they were glass, and had no idea that they are like plastic or glass coated in plastic. Anyway not what I'd expected but my fault for being the domestic goddess I am & no idea what Correll was. 
So for what they are, which is a glorified fortified paper plate, it's pretty and light and strong---I accidentally banged it against the sink's porcelain and it didn't break. 
Am keeping them as it's my mistake and I'll end up using them.
