As a subject matter expert in the field of materials science, I can provide you with a detailed answer regarding the composition of modern candles.

Candles today are primarily made from wax as the fuel source, which can be derived from various sources such as paraffin, beeswax, soy, or palm oil.
Paraffin wax is the most common type of wax used in candles due to its affordability and availability. It is a by-product of the petroleum industry.
Beeswax is a natural wax produced by honeybees and is often used for higher-end or specialty candles.
Soy wax and palm wax are plant-based alternatives that are considered more environmentally friendly.

In addition to wax, candles also contain a wick, which is typically made from braided cotton. The wick's purpose is to draw the melted wax up towards the flame, where it can be vaporized and burned.

Some candles may also include dyes and fragrances to enhance their visual appeal and provide a pleasant scent. However, it's important to note that not all candles have these additives; some are made with pure, uncolored wax and without added scents.
