There are a lot of companies that sell pizza stoneware. A popular one would be the Pampered Chef. They make a great one.
Some of the more popular Pampered Chef products you can buy at Pampered Chef parties are: the mandolin which slices everything from veggies to meats. Another favorite is the ice cream scoop which thaws the ice cream as it scoops it out. The pitcher is a favorite because it has a pressure top and liquid measurement markings. The stoneware is an all time favorite.
The Pampered Chef was created in 1980.

Do worry about it too much if it was the first time. Just make sure that you rinse thepapered-chef stone ware very well. I have done this myself by accident and no harm came from the one time.
