Gas ovens work by mixing natural gas and air to produce heat. When the thermostat is set, a fuse lights the gas as it seeps through a burner snaking inside the oven. The burner has multiple holes in it for the lighted gas to escape from, allowing the heat to spread throughout the oven's interior. Modern gas ovens have electric pilot ignitions that create a small, continuous flame that increases in temperature and height by twisting a corresponding knob to the area in use4. The temperature of the oven stays consistent throughout the entire cooking period.
