Learning to use a new tool

Anyone can build a fire, right?  I am discovering how to use my newly constructed Pizza  Oven and what can be done with it.  It is like any other tool I have acquired in my life, I want to master it.  There is a lot to learn!  I have had four fires now and the first one was a disaster!  Way too cold and during construction I filled the Oven with sand to stabilize the curve of the bricks as they were being mortared into their arch.  I did not get all of the sand out in the cleaning process and we had under cooked and sandy Pizzas!  The second fire was better, I got the oven to 500 f. degrees but it wouldn't hold the temperature and they were "eight minute pizzas".  Not sandy anyway. You can make great pizzas with a two hour head start on the fire but this last, forth try I was after perfection and I wanted to see what this oven was capable of.  I began the fire at 8 AM for a 2 O'clock cook time and did I ever get it HOT!  I used a very dry mix of Oak and Madrone, filled the very back and built a pretty Big Fire in the front.  When the "front fire" was down to a bed of coals I spread them evenly around the hearth and left them there for an hour before pushing them to the back of the oven igniting the logs left there.  By 2 O'clock the fire in the back was a foot deep bed of coals and the oven registered
over NINE HUNDRED DEGREES!  Even four hours later, without adding to the fire it was over 700 degrees. Pretty amazing.  We cooked Pizza in 74 seconds!!!
The Party was a lot of fun.  We had people from 4 months to 74 years old, three guitars and four singers!  It was a fun "old people's party" of neighbors and friends.  2 o'clock to 7 PM.  Perfect!
We made 25 pizzas, two chickens and a fantastic blueberry cobbler all in the Pizza Oven.  We could have cooked all night!
I also cooked a Brisket on the open fire pit with the rotisserie.  Even Jimmy Torres (You can Google him!) said it was the best brisket he had ever had!  Cooked for 7 and 1/2 hours over a bed of coals on a well tended fire.
