Is the cup only fully made of ceramic, buying as a gift and want to decorate outside but will need to bake in oven to seal.

Yes. There is a rubber plug in the bottom of the cup and a sticker that should be removed before baking but the body of the cup is one piece ceramic. I did the same thing. It worked great.

The cup itself is fully made of ceramic, but the cap and plug in the bottom are silicone. I would remove the plug before baking.

There is a hole in the bottom that is plugged with a silicone plug. Silicone can handle 400F typically.

I actually just did this project. It has a silicone lid and stopper on the bottom that need to come out before putting it in the oven. But it works great for a sharpie decorated coffee mug

It is ceramic all around and has a removable rubber stopper on the bottom of the cup (a small circle the size of a quarter).

There's a stopper at the bottom of the cup that's made of, most likely, rubber. It might be possible to remove it and then put it back, but I haven't tried.

No. And be wary - it is a very fragile ceramic. Cute - but broken upon delivery.

Not ceramic. It just appears to be a hard plastic. Only use for storage, not heating.

No, it's not and this is a great cup! Rim is not even warm and I use it everyday, keeps my coffee warm and doesn't spill over.

Yes, I searched a long time to find these for a christmas gift, they are good quality. Be careful of the really good deals out there because some are just a plastic cup glued to a stem. These are all ceramic.

Hi. Yes it is ceramic all throughout. It is closed on 3 sides and open in the back. It's a great product.

It doesn't dry like ceramic. You bake it in the oven and it feels more like plastic (it's polymer so it actually a form of plastic). If you had a very delicate, thin piece on your creation, it might break of if you drop it right. If you have a more solid creation, I don't believe it would break if you dropped it.

If you are asking if it is ceramic, no. It is not cast iron either. Best to direct your question to the manufacturer.

I bought them as a gift for a friend who LOVES cooking. From what I can remember, they were ceramic. My friend loves them.She says they seal well and seem durable

yes it is a ceramic mug and is microwave and dishwasher safe. I take the lid off when I put it in the microwave, just to be on the safe side.

Yes, it is. The ceramic is not heavy duty like a Starbucks mug though. Glaze will chip if you have somebody who is hard on mugs.

The cup is non ceramic, it is plastic and is 16 oz. to the very top....an excellent cup as it is not extremely large and is easy to hold and fits nicely in car cup holders.

No where on the packaging did it say it was or was not. It is a very sturdy cup and can be put in the dishwasher top rack. I am guessing it would work in the microwave, but I have never tried it.

No. I'm sorry. It's made from Melamine~ an older, non-porous plastic. If you want a large batter bowl you can bake in, check with Pampered Chef. They have an 8 cup glass measuring/batter bowl.

It is the same plastic as the outside, only smooth not textured. There is insulating material within the walls of the cup that keeps ice from melting for several hours. I have never used one for hot coffee, they hold a whole quart!

It's nonstick, not ceramic. We use it a couple of times a week and still love it!

No, the ceramic version does not rust. It is made from the same ceramic as a coffee mug.
