Abstract: This study tries to find out the possibility of the used cooking oil as an additive component of candle. This study aims to produce a low-priced but high-quality candle by using used cooking oil as a major component.
The following materials: 500 mL used cooking oil, 1 kg paraffin wax, cotton thread cut into 5 inches long, serves as, wick, crayons in different colors ,a can (like the can of century tuna), beaker, barbecue stick, plastic molder.
We conducted the experiment. The measured paraffin waxes will be cut into small pieces together with the small pieces of crayon that with be placed in the can. Then the can will be heated in low fire until the waxes and crayons melt and oil will be added different percentages of used cooking oil. Before the mixture solidifies, they will be formed into molds, wicks suspended in the middle of the container. They will be air-dried until hardened.

But Emission gases were analyzed for more than 300 chemicals known or suspected of toxicity, health risks or respiratory irritation at elevated concentrations. A new, internationally funded study on candle emissions has confirmed that well-made candles of all major wax types exhibit the same clean burning behavior, and pose no discernible risks to human health or indoor air quality.
