Question: What exactly is this pizza stone made of? Any artificial smells emitted when it warms up?
Document: I bought this stone for my sister because she broke the one she had for years. The problem with this stone is it smells funny and makes your food taste like it smells. We have tried and tried to &#34;season&#34; the stone, but nothing changes, the smell is still there. Her original stone came from Pampered Chef and never smelled funny or made the food taste funny. I guess we will just get another one from them.
The stone does not have a pleasant odor when heated. The whole house smells of it whenever we are using the oven. Take it out and store it when not in use, you say? It's huge and heavy and takes up a too much space in a cabinet.- Some pizza sauce spilled on it early in use. About 25% of the stone is now black.
The pizza stone is a first for me. It was exactly what I wanted to bake Artisan bread and pizza. The size is perfect.
Exactly what I wantd for a small pizza. Light enough to lift and not have to use a huge stone for a small pizza.
This works exactly as promised, allowing us to make our pizzas with a crisp crust. We keep ours clean by putting baker's paper between the stone and the pizza.
We make homemade pizza about once a week. When our stone broke I was forced to replace it and decided to look for a stone slightly bigger than the one we had. The Old Stone is exactly what we needed.
Works great. The only way to consistently make perfect pizza is to use a stone. My wife and I have used other more expensive ones at our parents' houses. We went ahead and bought this one based on price and it works exactly as well as the more costly ones.
The downside is cornmeal falls to the bottom of the oven and instantly burns and smells (and smokes). now I sprinkle it on and hold a baking sheet underneath to catch the cornmeal that falls off the edges.I also generously flour and cornmeal the peel before I put the pizza on. I've had no problems with pizza sticking.
I make pizza at least once a week for dinner. That's the easy part - each person wants a very different pizza, which is difficult with a large stone. These are the perfect size for individual pizzas. Great product, shipped exactly per terms. Will buy more for parties etc.
The product was exactly what we were looking for...unfortunately, the packaging was horrible (the box was much too big, with inadequate packing material). So, we received a very nice pizza stone - which was chipped. Guess we'll just have to make oddly-shaped pizzas, since we wrote to Amazon, but got no response. If you order this product, be sure to ask for someone with basic common sense to be involved in either the packing and/or inspecting of the box.
Answer: It is a porous ceramic material.   Mine has not emitted any smells.  I have had mine for about a year and it works well.  I leave mine in the oven as a temperature stabilizer, and use it to cook pizza.
