It is feasible to make candles out of used cooking.
Candles out of used cooking oil can be comparable to candles out of paraffin wax (commercial candle) in terms of:
a. Lifespan
b. Type of flame
Scope and Limitations
Upon conducting the experimentation process, the researchers had found out some limitations within the projects and these are the following:
1. The researchers did not include the measurement of the amount of light given off by each candle because the instrument used to measure was not available in the surroundings.
2. Upon testing the candles quality, the researchers only include the following parameters:
a. Lifespan of the candles
b. Type of flame produce by the candles
Definition of terms
Candle - a stick of solid wax with an embedded wick burned for light
Hydrocarbon - are compounds that can produce light to candle
Stearic acid - serves as the hardener in candle making
Paraffin wax - a white, waxy substance consisting of a mixture of Hydrocarbons, distilled from petroleum and used for making candles, sealing jars, etc.

Significance of the Study
In our country, today more ways are now made to utilize common things in order to make products easier and cheaper. In this research study, used cooking oil is used as an alternative for paraffin wax in candle making.
In the field of science, this study contributes a lot for the reason that we can find alternative for paraffin wax as main component in candle making; besides paraffin was derived from petroleum and the latter is much expensive. This study contributes knowledge to the researchers and also to the community in the sense of finding an alternative way to utilize used cooking oil that may pollute and clog canals and sewerage system if not recycled and used again in essential ways, instead of chemically synthesized sources. It also improves the human condition physically in minimizing the waste oil that pollutes our country.
