Which substance is used for making candles?

Paraffin wax

The correct answer is option 2. paraffin wax.

Paraffin wax is a type of hydrocarbon wax derived from crude oil during the refining process. It is a white or colorless, odorless solid at room temperature and has a low melting point, making it suitable for various applications, including candle making. Here's a brief explanation of why paraffin wax is commonly used for making candles:

1. Melting Point:  Paraffin wax has a relatively low melting point, typically in the range of 120 to 160 degrees Fahrenheit (49 to 71 degrees Celsius). This characteristic allows candles made from paraffin wax to melt and release fragrance when burned, making them suitable for scented candles.

2. Consistency:  Paraffin wax is easy to work with and mold into various shapes. It can be poured into candle molds, allowing for the creation of candles with different sizes, shapes, and designs.

3. Burn Characteristics:  Candles made from paraffin wax generally burn cleanly and evenly. The wax provides a steady and consistent flame, making it a popular choice for candle manufacturers.

4. Affordability: Paraffin wax is cost-effective, which contributes to its widespread use in candle production. It is readily available and can be easily manipulated to achieve different candle properties.

While paraffin wax is a common choice for candle making, there are also alternative waxes available, such as soy wax and beeswax, each with its own set of characteristics and advantages.
