How did thermostat improvements make ovens more useful?

The development of the oven was significantly enhanced by advancements in thermostat technology throughout the 19th century. By enabling effective temperature controls, these improvements transformed ovens from basic heating compartments into precise cooking tools.1

These automated controls allowed for consistent heat management, which was essential for the evolution of the modern gas and electric range. By providing reliable temperature regulation, thermostats helped pave the way for further automation, such as versatile timers that allow meals to be cooked automatically at preselected times, even in the absence of the cook.1
