What is stoneware? What is the different between stoneware and ceramic? Does it has any safety standards? Thank you.

The stoneware is made of ceramic, with a glaze. The glaze is made of silica flour, clay, feldspar, something called "frit", and a few minerals. These are ground up mixed, in specific quantities, with water. The resulting slurry is sprayed onto the pot (or the pot is dipped in it) and it is fired in the kiln at or around 1200-1600 degrees. It all melts together on the outside of the pot and basically turns into a type of glass. All of the glazes that we use meet or exceed FDA requirements.

Also from many years of cooking etc. Stoneware tends to get alot hotter I.E. (using in the microwave). Ceramics do not. Stoneware also tends to start cracking after years of use. Ceramics I have used last years longer before they start to have the small hairline cracks in them. Hope this helps :)

Hi: I am really not an expert but I do have some basic knowledge through my own personal research over the years due to my own awareness of what materials I am cooking my food in. Stoneware is simply a clay type of material and completely safe. Ceramic has a different type of finish. Stoneware is more clay type base but both of those are great to cook in. There are no safety standards based on my research. Actually it is highly recommended.

I tried to Google for help, and found some discussions but no definitive instructions - 1. Good cleaning with warm/hot water. 2. Cracking the stone bowl seems to be a real concern, and I can see the possibility with fast uneven heating of the bowl if it has a crack in it already. 3. No seasoning is necessary as with the cast iron cookwares.

Hamilton Beach advertised this product as being Stoneware. My research shows "American Stoneware was valued as not only a durable, decorative houseware but as a safer alternative to lead-glazed earthenware pottery produced in America before and during its production there." You should present that question directly to the manufacturer to be sure.

Scientifically, there's not that much difference between glass and ceramic pots. It's more important to keep the lid on and use a tea cozy.

Stoneware. Not as heavy as our old 7 quart but perfect for us. Nice machine. Love the keep warm after cooking. Our old cooker did not have that operation.

Ceramic. It is NOT stone ware. It will break if dropped on the ground. I own one myself and I take great care of it. Otherwise a fantastic product.

I gave the bowls as gifts in December so do not have them with me now. I believe that they were stoneware. They were very nice - all recipients have been very pleased with them. Highly recommended!

As far as safe - this should be theoretical, who would know the difference between the process of ceramic vs. clay? My feeling is that clay theoretically SHOULD be safer/healthier, in that the process of manufacturing is minimal in comparison to ceramic. But then ceramic is so much 'nicer and cleaner looking'. Safe may be a question of time - over a long period of time. Sorry I have no idea as to the 'safe' aspect but the manufacturing process should be a factor. by Ken W

Stoneware. It is heavy duty. I like it. But, it weighs a lot, so if you were looking for something lightweight, this wouldn't be a good choice. I think it makes great coffee.

Well, the rule goes like this: "Glass and glass ceramic cookware is microwave safe as long as it doesn't have gold or silver rims.", so it's safe :)

I'm not sure that it is stoneware, but it certainly is heavier than bone china. They have a sturdy look and feel.

Stoneware is notorious for having glazes that have lead. That being said, there are many glazes that do NOT have lead in them. I bought one of these pots at Walmart and it occurred to me that it was glazed differently from the one shown here. Then I got to thinking about lead in the glaze. I ended up here trying to find out if the pot was lead free. So far no answers to that question.

Stoneware is fired at 2370 degrees. I'm pretty sure it can take 425 degrees. But, like any high fired ceramic pieces, be careful to avoid thermal shock by lowering the heat gradually. Enjoy!

Handwashed and not oven safe--but it is so easy to clean--no scrubbing or sticking. Don't know why you would want to put them in the dishwasher. --I have the 8 piece set--I use very little oil--about half as much. . Love working with the food against the white interior--you see what is happening so much better. Also use much lower heat and get great fast results. They call it ceramic but that is only true in the sense that it is a glass covering as the glaze on ceramics is essentially a form of glass--not clay. Karl

I have these dishes in black and unfortunately chipped a coffee mug. Now that I can "see" the inside, it is definitely stoneware, not bone china.

I never put any knives in the dishwasher because it is not good for them. I had a father who was a butcher and he always lectured me on this. I can not say if it is different for ceramic knives. Sorry.

They are ceramic. The packaging labels them as stoneware. Additionally, they are dishwasher and microwave safe and also stated to be leadfree.
