162: Fire in the hole!

Our wood fired pizza/bread is done! John did an amazing job on it. The core is refractory stone mounted on a two-inch refractory fiber board set on top of a four-inch concrete block base. The core was then wrapped in a three-inch ceramic fiber blanket with a wire mesh casing to hold it in place. John then encased everything with a one-inch layer of refractory concrete. The idea behind this is to get the oven to hold extreme temperatures inside, yet be cool to the touch on the outside. Success!

Yesterday morning we fired the oven up and let it go all day while we went to the beach. When we got back, some 6½ hours later, the inside temperature was over 350°F. and the outside wall was cool to the touch.

John stoked the fire up again in the evening and bought it all the way up to 510°Celsius, or 950°Farenheit!!! The outside temperature was 100°F or less. You can definitely lay you hand on the side of the oven and not worry about getting burned.

Today, just in time for my birthday, we are going to give it the real test and actually bake pizza. This will require a wood fire be brought up to temperature in the oven to heat it up. Then the coals will be pushed to one side, or removed for baking.

Time to go make the pizza dough and sauce. Yum!!
