Why is my gas cooker producing soot?
If you are using LP (liquid propane) gas as your fuel source and your gas flame is fully yellow, or if you have a buildup of soot or carbon around your burners, this is usually a problem with air flow or gas pressure, "bad" gas, or the orifices need to be changed.
If your propane burner and pilots are not clean, the appropriate burning of liquid propane is hindered. This creates a situation where the molecules that escape into the air will accumulate on the surface of your feature, appearing as black soot.
Gas Stove Making Pots Black
Adjust your air intake valve on gas stove until you see only a blue flame gas stove color, and that should fix the problem.
All of the carbon that gets used can be turned into carbon dioxide, so there's actually no soot. Complete combustion of LPG takes place. Hence, it burns with a blue flame.
Over-watering plants can cause a plant's leaves to turn black. Often by this stage, the plant has irreversible rot and cannot be saved. To prevent this, don't let your plants sit in too much water and make sure that the pot it's in has a hole at the bottom so any excess water can escape.
Try burning harder woods like oak, cherry, or walnut, and avoid burning woods known for their higher sap content. If your wood stove has a heat setting, try turning the heat controls up a few notches. Hotter fires will keep your glass cleaner. Allow enough oxygen to vent into your wood stove.
The first issue to note is that the presence of a large amount of soot could indicate that carbon monoxide is in the air. The main reason for this observation is that carbon monoxide is a natural result of combustion.
Fill your wash basin/sink with warm water and mild dish soap. Add enough water so that when you put the pot into the water in will not spill over into the pot. Leave pot in soapy water for 5-10 minutes. Step 3: Go outside and cook an amazing meal over an open flame or hot coals.
The black residue that sticks around after a fire, a.k.a. soot, is the result of incomplete fossil fuel combustion. When coal, oil, wood or other fuels are burned, the residual material, comprised mostly of carbon, can travel through the air and settle into the surrounding environment.
Thick, black smoke indicates heavy fuels that are not being fully consumed. At times, black smoke can be an indicator that a manmade material is burning such as tires, vehicles or a structure. As a general rule, the darker the smoke, the more volatile the fire is.
What causes black smoke from?
Billowing black smoke is generally a sign that the fuel-air ratio in your engine is too rich. This means that the fuel injectors are either adding too much fuel or that the intake valves aren't letting enough air in. This could be caused by a leaking fuel injector, a faulty fuel pressure regulator, or a bad air filter.
Pots and pans used on a gas stove sometimes develop black marks on them. This sooting or staining can be caused by uneven heating, heat that is turned up too high, or even a dirty stove top.

The most significant sources of soot are diesel engines, vehicle tailpipes, coal plant smokestacks, oil refineries, and fires—the burning of large forests for agricultural purposes produces soot, and so does the use of grills, fireplaces and cookstoves for cooking and heating.
Black soot is a black particulate matter made up of carbon and results from the incomplete combustion of fossil fuels.
Soot forms when reactive molecules found in flames set off a chain reaction. Reactive molecules form and quickly bind with other hydrocarbons. The reaction forms the seed of the soot particle, but the process isn't done. The binding creates reactive molecules.
How It Works: Fill your dirty pan with equal part water and vinegar. Bring the mixture to a boil and then add 2 tablespoons of baking soda. Remove from heat and let soak for up to 15 minutes. Discard the liquid down your drain and then use a sponge or scouring pad to scrub away any remaining burnt-on bits.
Solution: The bottom of the cooking utensils are painted black because black surface absorbs more heat and so the contents of the utensil gets cooked rapidly.
The coating on nonstick cookware contains a chemical called polytetrafluoroethylene (PTFE). DuPont's Teflon is the most well-known brand. When heated to very high temperatures, this coating creates hazardous fumes.
Essentially, soot gets into the human body through ingestion, inhalation, or through the skin and eye. When in the body, soot particles can cause coronary heart disease, breathing issues, including asthma, and even cancer.
Soot can enter the body through inhalation, ingestion or via the skin and eyes. These toxic particles can cause breathing issues, including asthma, bronchitis, coronary heart disease, and even cancer. Infants, the elderly, and those who already have breathing problems are the most affected.
Is soot cancerous?
Which cancers are associated with exposure to soot? Exposure to soot was first associated with skin cancer of the scrotum among British chimney sweeps in 1775. Since then, many studies have found that chimney sweeps have an increased risk of scrotal and other skin cancers.
Abstract. Carbon blacks are manufactured under controlled conditions for commercial use primarily in the rubber, painting, and printing industries. In contrast, soots are unwanted byproducts from the combustion of carbon-based materials for the generation of energy or heat, or for the disposal of waste.
Deadly fine particulate matter, also known as soot, is caused by pollution from tailpipes, smokestacks and industrial power plants. Breathing soot can cause premature death, heart disease and lung damage.
The most likely effect of exposure to carbon black is lung disease. Inhaling carbon black particles can irritate the lungs and cause coughing. Carbon black can also irritate the eyes, nose and throat. When people are exposed to high levels of carbon black over many years, the particles may lodge deep in their lungs.
The blackness left behind on your pans is actually soot resulting from incomplete combustion due to a lack of oxygen.
