well I've had a lifelong interest in making pizza. I was just looking around for pizza schools and found this website http://www.pizzaschoolnewyork.com/4-day-pizza-school-course/. I mean 4 days and ba da bing you probably learn more than you would in a lifetime in your home kitchen. It's all men in the pics, though. Either while in or just out of high school, I wanted to make pizza in a local pizza shop, but was told by the proprietor that it would bring bad luck to have a woman making the pizza. Nowadays folks can't say things outright like that, but the issue isn't resolved by silence. It is a male dominated industry--I've never seen a female pizziola (I think that would be the feminine form of pizziolo, but "pizziola" might mean something else--the feminine form may not exist). I imagine it's a lot of hard work, but a real chance to develop and hone skills.
What I wonder is--is there a heating element at both the top and bottom of each level of a pizza oven--you know the big stainless ones with multiple decks. Are they gas or electric?
