Should Flames Gas Fire Blue

Gas flames should be blue but can sometimes burn red or yellow.

Why is the flame on my gas stove orange and blue?

If your gas stove is producing a hissing blue flame, proper combustion is taking place and consequently the production of normal carbon monoxide levels. However, orange flames mean an increased level of poisonous CO gas, which is not safe for your health, utensils, and home décor. Blue flame means proper combustion.

Why is my gas stove flame green?

Green flame can be caused by copper salts or corroded copper parts contaminating the flame with copper ions. This can “naturally” happen, and the minute amount of copper is harmless. However if someone intentionally put larger amount of toxic copper salts there, that might be dangerous.
