Hypothesis

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.
