Cotton wicks are thin strands of cotton fibers used to draw liquid, such as oil or wax, up into a flame to produce light or heat. These wicks are commonly found in candles, oil lamps, and even certain types of incense, where they play a crucial role in sustaining the burn. Made from natural cotton, the wicks are soft, absorbent, and durable, which allows them to efficiently draw and hold the liquid fuel to keep the flame steady and controlled.

In candles, cotton wicks are often braided or twisted to maintain an even burn. The thickness of the wick can vary, depending on the size of the candle and the type of wax used. The cotton fibers are highly absorbent, ensuring that the wax or oil is consistently fed to the flame without it flickering or extinguishing.

Cotton wicks are favored for their eco-friendliness since they are made from a renewable resource and tend to burn cleanly, emitting little to no harmful chemicals. As a result, they are often used in natural or handmade candles. The gentle, consistent flame created by cotton wicks also enhances the ambiance, making them popular for creating a warm, inviting atmosphere in homes, restaurants, and relaxation spaces.
