wood fired Pizza oven build cast from perlite concrete how to

Our pizza oven build. Thanks to everyone for posting your build videos it gave us the idea and inspiration for this build. You can see my little helpers running around, unfortunately i did not make videos of the cement mixing and pouring as it was hard to hold phone with dirty concrete covered hands. But i am posting my list of all supplies here.
The frame was built of pressure treated lumber with a concrete and masonry brick flat base 4 inches of concrete plus brick and the dome was cast in one shot with the walls at 3" thickness at their narrowest points. I will make an updated video when we finally fire it after a month of cure time but here it is for now, please let me know what you guys think and also any other cool build ideas I can try with my kids next.
