The inside is white enamel. This is basically a knock-off le creuset item, and works just as well as an owner of both) I am unsure about the warranty. I'm really bad about those things. I will say that I've used this MANY TIMES, and even banged it around a bit. No chips in enamel or anything. It's one of my most used pots/pans (along with an all-clad "essential" pan and my copper pots).

Exterior surface is stainless steel finish, but the interior is a non-stick, Teflon-like coating.

I am not home right now to verify. However, I believe its metal internals covered with plastic.

The interior you see inside is metal. But based on weight, i think the insulating material is probably glass.

Inner lining is stainless steel. Check out Eccl Vessel as well that is also stainless steel inside.

Sorry, I can't tell. It is coated like teflon. This is my second one and i use it everyday.

Appears to be a teflon type coating. Not really sure. I would recommend asking the manufacturer.

The interior is metal. We use the disposable small aluminum loaf pans inside of it to warm the food. We buy those at Walmart for a reasonable price.

The inside is just stainless steel, no coating. The gasket is not in touch with the water at all. The key to making good espresso with these, is using medium heat, and soon as it's done "gurgling", remove from the stove. Mix with a spoon before pouring.

I haven't had any trouble with the coating or overall durability of this product. I am genuinely pleased with mine after two years and continue to recommend it to anyone with a KitchenAid.

The interior is stainless steels which I really liked. I did not observed lots of steam when it was still working. That been said, however, it probably will only last for a year, according to my experience. I will not buy from this brand again.

There is a two year warranty for loss of no-stick properties or peeling of the coating if you use and maintain the pan according to their instructions.

The interior is not coated with non-stick. The interior of our toaster ovens are made of galvanized or aluminized steel.

The inside surface is stainless steel and outside surface is hammered colored stainless steel. There is a very thin layer between that is a fantastic insulation. I use mine for cold drinks and it keeps them cold for a very long time. Left a half drink on my desk with 2 ice cubes in it at work one evening with the top removed and the ice was still there the following morning,

The warranty is 2 years. I've had to replace mine twice in the last year, with no issues.

We are on our second one. The first one we bought in 1997, and just replaced it last year in 2012. We keep it on the counter, and it was plugged in and working 24/7 from when we first got until we replaced it. The coating was never a problem. We love it, and someday, when this one quits, we'll buy another one the same day!
