Wicks
Wicks are a component of many combustion devices, serving as the carrier of fuel to sustain a flame. They are typically made of a fibrous material that draws liquid fuel via capillary action to the burning point.
Material
Historically, wicks were commonly made from cotton. Modern wicks utilize a broader range of materials, including:
- Cotton: Remains a prevalent choice, particularly for candles due to its affordability and good wicking properties. Different cotton constructions (e.g., flat braid, square braid) affect burn characteristics.
- Paper: Often used in conjunction with other materials, or as a core within a braided wick.
- Synthetic Fibers: Acrylic, nylon, and polyester fibers offer controlled burn rates and can be treated for specific fuel types.
- Metal: Metal core wicks (e.g., zinc, tin, copper) provide rigidity, allowing for larger flame sizes and use with waxes that standard wicks cannot support. They also reduce mushrooming.
Purpose
The primary purpose of a wick is to deliver a consistent supply of fuel to the flame, enabling sustained combustion. They are essential for:
- Candles: Providing illumination and fragrance.
- Oil Lamps: Delivering fuel to the flame for light.
- Kerosene Lamps: Similar to oil lamps, but using kerosene as the fuel source.
- Alcohol Burners: Supporting the flame for heating or sterilization.
Function
Wicks function through a combination of physical properties:
- Capillary Action: The fibrous structure draws fuel upwards against gravity.
- Combustion: The exposed portion of the wick is ignited, vaporizing the fuel and sustaining the flame.
- Fuel Delivery: The wick regulates the rate at which fuel is delivered to the flame, influencing flame size and burn time.
- Vaporization: The heat from the flame vaporizes the liquid fuel, making it combustible.
Usage Scenarios
- Home Ambiance: Candles with wicks are widely used for decorative lighting and fragrance.
- Emergency Lighting: Oil lamps and kerosene lamps provide a reliable light source during power outages.
- Scientific Experiments: Alcohol burners are utilized in laboratories for controlled heating.
- Outdoor Activities: Lanterns with wicks provide portable illumination for camping and hiking.
Common Types
- Flat Wicks: Commonly used in container candles; provide a consistent burn.
- Square Wicks: Offer a more robust flame, suitable for larger candles.
- Cored Wicks: Contain a metal core for rigidity and stability, used with softer waxes.
- Tab Wicks: Pre-tabbed for easy insertion into candle containers.
- Self-Trimming Wicks: Designed to curl over and self-extinguish, reducing mushrooming and soot.
- Wooden Wicks: Produce a crackling sound and unique aesthetic.
