A propane torch can reach temperatures of up to 3,623 degrees Fahrenheit when used in the open air. The flame generated by a propane torch is made of an inner and outer flame. The inner flame is dark blue, while the outer flame is a lighter shade of blue.
Propane is a naturally occurring component of crude oil and natural gas. When found in nature, propane is both odorless and colorless. When used in a propane torch, a special compound is added to the fuel to give it a smell that allows users to detect any leaks. Propane torches are primarily used for heating and cooking.
