Why Does An Oil Lamp Need A Wick ?
The function of an oil lamp wick is to transfer the fuel from the burner to the flame. Capillary action pulls liquid fuel through the wick and stops the burning of the wick; the fire is actually burned over the top of the wick. The warmth is burned through the wick bottoms.

Oil lamp wicks are available in a variety of sizes and materials. Choosing the right wick size you need will depend on the size of your kerosene burner. The most common material for oil lamp wicks is cotton, but there are also wicks made from other materials such as fiberglass or Kevlar.
The type of oil you use will also affect the type of lamp wick you need. For example, if you are using a light oil such as mineral oil, you will need a different wick than if you are using a heavier oil such as olive oil. Heavier oils will require a thicker wick in order to maintain a steady flame.

2. The round wick provides good air circulation around the flame, which helps to prevent soot buildup.
3. The shape of the wick also allows for a more even burn, resulting in less waste of fuel.

A tubular wick is a type of oil lamp wick that is made from a hollow tube of textile material. The most common type of tubular wick is made from cotton, but other materials such as linen or hemp can also be used.
Tubular wicks are used in oil lamps because they allow the oil to flow evenly and steadily up the wick, which provides a consistent and steady flame.
There are several benefits to using a tubular wick in oil lamps:
- Tubular wicks provide a steadier and more consistent flame than other types of wicks.
- Tubular wicks allow the oil to flow evenly up the wick, which prevents the formation of hot spots and ensures that the entire wick is used.
- Tubular wicks are less likely to smolder and produce smoke than other types of wicks.

Cotton Flat Wicks For Most Oil Lamps
High-quality cotton is used to make clean-burning and rapid transportation of fuels. Cotton wicks are most readily available and are suitable for use in most domestic applications.
Fiberglass Oil Wick
A fiberglass oil wick may be a good choice over a cotton oil wick in certain situations. For example, if you are looking for a more durable wick that will last longer, a fiberglass wick may be a better option. Additionally, fiberglass wicks can typically handle higher heat than cotton wicks, so they may be a good choice if you are using your oil lamps in a high-heat environment.
Kevlar Oil Wick
Kevlar oil wicks are made of a heat resistant material, so they can be used in situations where a cotton or fiberglass oil wick might break down. Kevlar wicks also tend to last longer than other types of wicks.
If you use your oil lamp in a very hot climate, the heat can cause the wick to break down. Also, if you do not trim the wick regularly, it can get too long and begin to break down. Additionally, if you use an oil that is not compatible with the wick material, it can break down the wick. Finally, if you allow the oil level in the lamp to get too low, this can also cause the wick to break down. All of these situations will result in an oil lamp that does not work properly and will need to be replaced.
