If it’s the Charcoal Companion Pizza Que then I’d say it’s quite high. A lot of people will tell you that the only way to cook up a truly great pizza is with the high heat that only a pizza oven can provide. Unfortunately most consumer home ovens simply can not produce the heat required to get a perfect crust. Enter the Pizza Que, made to work with your outdoor charcoal or gas grill both of which can hit the temperatures required to make the perfect pizza. Hit the link for more.
The porous clay cooking surface is made to retain the heat and the stainless steel base includes a thermometer so you know exactly when the pizza stone is ready for use. For charcoal grilling simple create a ring of hot coals around the outside of the grill and place the Pizza Que in the center, dust the surface of the stone with corn meal (to prevent sticking) place your pizza on the stone and cook until you have a beautiful golden crust and your ingredients are cooked through. You can even add your favorite wood chips to the coals to give you a nice smokey flavor to your pizza. Instructions for gas grilling are similar just make sure that you do not place the stone directly over the flames. Street prices appear to range from $71.95 all the way to 99.95, regardless of the price with the Pizza Que you will never have a limp crust again!
And pizza being an american favorite, why arnt oven makers scrambling to put a blast furnace in every house? Not just great for making pizza but for glass and metal hobbiest as well!
