The term "900°F" refers to a high temperature that is often associated with industrial processes, cooking, or scientific experiments. At this temperature, many materials, including metals and ceramics, can undergo significant changes in their physical properties. For example, metals may become malleable, while certain types of glass can soften. In cooking, reaching 900°F is typical in professional pizza ovens, where it helps achieve a crispy crust and perfectly cooked toppings. This extreme heat allows for rapid cooking, which is essential for creating traditional styles of pizza, such as those from Neapolitan or New York.
