Consequently, are Corelle dishes toxic?

It is unfortunate that just about everything around us can be toxic including our dinnerware! Dishes made with ceramic, porcelain or china can contain lead or cadmium since glaze is used. Corelle dishes are thin and translucent as fine china, yet extremely stronger.

Also, what is the most durable dinnerware material? Despite its fragile presentation, bone china is actually the strongest and most durable ceramic dinnerware. Most bone china is dishwasher-safe and, unless it has metallic banding, can go in the microwave and oven as well. Bone china, as with porcelain, can be used daily or reserved for a more formal dining occasion.
