Hi Omid, thanks for thinking of me and going through the effort of posting up a picture. You must have been at Lowe's Home Improvement store, as I remember seeing the same ceramic oven a few months back at my local Lowe's. It was literally set up in the same spot amongst the BBQ grills and displayed in the same fashion.
I don't have the same ceramic grill but I do own the Primo Ceramic grill. It is essentially the same grill except it is oval shaped and has a larger grilling surface. As a matter of fact, my pizza journey began in the Primo Ceramic grill on another forum. It was only after a few months of experimenting, did I find this forum. If you can believe it, I have tried numerous configurations and setups in the Primo Ceramic grill including setting up a mini oven inside the grill much like what you did in your home oven.
You can see some of my experiments on this grill in this thread...
http://www.pizzamaking.com/forum/index.php?topic=10974.0For those people who like the look of my pizzas now, you should really check out that thread. It has a lot of my earlier pizzas which were rather subpar looking.
I didn't always know how to make pizza and struggled as much as anyone else does with making the dough.
Ceramic grills such as the one posted by Omid, the BGE, the Primo, etc make okay pizza ovens. They can bake an American style pizza at 650 for 6-8 minutes or more and do a decent job. It's becomes increasingly challenging when you ask it to bake a pizza at higher temps with a shorter bake time. The uneveness of the heat easily triples and becomes much more of a challenge to get a good even bake.
To bake pies at 750-900F, it takes much more charcoal, and it becomes very easy to toast the gaskets, and stretch the metal bands and hinges that hold the lid together. I have read of several reports of the lids coming apart during a high temp bake. You can see towards the end of that thread, that I was able to bake up some decent coal oven style pies but it was not without a lot of effort.
Ceramic grills are great for grilling, smoking meats, & bbq'ing in general but not the best tool for pizza. I found the LBE to work much better.
It's interesting to note that many members who buy these ceramic grills often have graduated from the metal charcoal grills and will have them laying around. If they haven't gotten rid of the metal charcoal grills, the LBE mod makes a great pizza oven. Very quick to heat up and can bake great pizzas once one balances out the heat distribution of course.
Cheers,
Chau
