Hi, dayna, and welcome to DC.
Now, for your pot. Are you sure it's stoneware or ceramic? Is it possible it could be enamel-coated cast-iron? Perhaps something like Le Creuset.
Could you possiblly take a photo of it and post it so we can get a better idea of what it really looks like? What are the actual dimensions? Those would help, too.
You said you saw it on a cooking show. What kind of cooking show was it? Perhaps the cookware is some sort of ethnic piece.
At any rate, just be patient. You'll definitely get an answer here. There are many eyes.
