Reverse flow incense burners, also known as backflow incense burners, are a relatively new type of incense burner that creates a mesmerizing display of smoke flowing downwards in the shape of a waterfall. The incense smoke is denser than normal air at room temperature due to the tiny particles it contains. When the incense is lit, the smoke enters a hollow tunnel, where it cools and becomes even denser, causing it to flow downwards when it exits the burner. While the visual appeal of these burners is widely acknowledged, opinions on the fragrance vary, with some users complaining about unpleasant smells.

Reverse flow incense burners are designed to create a cascading waterfall effect
Reverse flow incense burners, also known as backflow incense burners, are designed to create a cascading waterfall effect. This mesmerizing effect is achieved through the unique flow of incense smoke, which moves in the opposite direction to "normal" incense. Instead of the smoke rising upwards, it gently cascades downwards, creating a soothing and hypnotic visual.
The science behind this reverse flow is based on the density of the incense smoke. When a regular incense stick is lit, the smoke moves upwards due to the heat generated, which offsets the weight of the particles in the smoke. However, in the case of reverse flow incense, the smoke enters a hollow tunnel in the burner, where it begins to cool down. As the smoke cools, it becomes denser, and when it exits the burner at the bottom, it flows gently downwards, creating the desired waterfall effect.
To use a reverse flow incense burner, one must follow specific steps to ensure the correct ignition of the incense cone. The pointy end of the cone is lit with a match or lighter, and it is important to ensure that the incense is fully immersed in the flame until it ignites. Once a small flame appears, it is gently fanned or blown out, leaving a glowing ember and smoke emanating from the bottom of the cone.
The visual appeal of reverse flow incense burners is undeniable, with many people captivated by the cascading smoke. However, opinions vary regarding the fragrance of the incense. While some people enjoy the aromatic experience, others have expressed disappointment, claiming that the incense cones smell horrible and leave an unpleasant odour in the room. Therefore, it is recommended to choose high-quality incense cones from reputable brands to ensure a positive overall experience.
Overall, reverse flow incense burners offer a unique and relaxing experience, combining visual beauty with aromatic pleasure. By understanding the science behind the reverse flow and selecting the right incense cones, individuals can fully appreciate the calming and spiritual benefits that these burners provide.

The incense smoke flows in the opposite direction to normal incense
Backflow incense, also known as waterfall incense or an incense fountain, is a type of incense where the smoke flows in the opposite direction to "normal" incense. That is, the smoke flows downwards instead of upwards. This creates a mesmerising waterfall effect as the smoke gently cascades down the burner.
When normal incense is lit, smoke flows upwards because the effect of the heat offsets the weight of the tiny particles it contains, as hot air is lighter than room-temperature air. However, in the case of backflow incense, the smoke enters a hollow centre tunnel as it burns. The smoke then cools as it travels along the tunnel, becoming denser, and exits the incense at the bottom, flowing gently downwards.
To light a backflow incense cone, hold a match or lighter to the pointy end of the cone until it ignites with a small flame. Gently fan or blow out the flame until only a small glowing ember remains and smoke starts to emerge from the bottom of the cone. If your cone is lit correctly, you should be able to see a glowing ember at the tip and smoke visibly flowing out of the bottom hole when you hold the cone in your hand.
It is recommended that you clean your backflow incense burner after every 2-3 cones burnt to prevent a build-up of residue.

The smoke enters a hollow tunnel, cools, and becomes denser
The key to the reverse flow incense burner is the density of the smoke. Incense smoke is denser than normal air at room temperature because it contains tiny particles. When a regular incense stick is lit, the smoke flows upwards because the heat generated offsets the weight of the particles—hot air is lighter than room-temperature air.
In the case of a reverse flow incense burner, the smoke enters a hollow tunnel in the incense burner where it cools as it travels along the path. As the smoke cools, it becomes denser. This density means that when the smoke exits the burner at the bottom, it flows gently downwards, creating the reverse flow effect. This effect is mesmerising to watch and can be guided to form different shapes.
The downward flow of smoke creates a hypnotic and grounding effect, helping to balance emotions and cleanse your space of negativity. The visual appeal of the smoke is a key part of the experience, with many people enjoying the soft, flowing smoke as it cascades down the burner. This makes the reverse flow incense burner a perfect companion for meditation, manifestation, and energy work.
While the visual aspect of the reverse flow incense burner is a key draw, the fragrance of the incense is also important. The incense cones used in these burners come in a variety of scents, including lavender, vanilla, and sandalwood. However, some people have reported that the fragrance is sometimes an afterthought, with the visual effect taking precedence. It is also important to note that the burner will need to be cleaned regularly to remove any residue from the incense cones, which can affect the smoke flow.

The burner should be cleaned after every 2-3 cones
To ensure your burner continues to work effectively, it is important to keep it clean. It is recommended that you clean your incense burner after every 2-3 cones. This is because, over time, resin from the incense can build up on the burner plate. This can impact the burner's performance and, if left too long, can be difficult to remove.
To clean your burner, start by ensuring the burner is cool to the touch. Then, take a damp cloth and gently wipe down the burner, ensuring you get into any grooves or patterns in the design. If there is stubborn residue, carefully use a small amount of mild soap or detergent on the cloth and gently scrub the area. Rinse the burner with a damp cloth to ensure no soap residue remains. Finally, dry the burner with a soft cloth and leave it to air dry completely before using it again.
If you are using a backflow burner, it is important to clean the inside of the burner as well. Use a small, soft-bristled brush to gently remove any residue from the inside of the burner. Be careful not to scratch the surface of the burner. You can also use a gentle cleaning solution, such as mild soap or detergent, to help remove any stubborn residue. Rinse the inside of the burner with a small amount of water and allow it to air dry completely before using it again.
Some people recommend using a small amount of table salt on a damp cloth to remove any strong odours from the burner. Alternatively, you can create your own natural cleaning solution by boiling lemon slices and water, allowing the mixture to cool, and then using it to gently wipe down the burner. This can help to remove any stubborn smells and leave your burner smelling fresh.

The incense cones are lit by being immersed in a flame
To light an incense cone with a flame, you will need a lighter or a match. Some sources suggest using a regular match or lighter, while others recommend using an electric lighter to avoid an open flame.
Place the incense cone on the burner, pointed-side up. Light the very tip of the incense cone and let it burn for 5 to 10 seconds. Then, blow or fan the flame out. The top of the cone should still be lit, but without a flame. The cone will start to smoulder and release fragrant smoke.
Monitor the amount of smoke produced. If there is too much smoke, adjust the cone's position or gently blow on it to control the burn rate. Keep an eye on the burning incense cone to ensure it remains stable and does not tip over.
Once the incense cone has burned completely and only ash is left, gently tap the holder to extinguish any remaining embers. Allow the ash to cool before disposing of it.
It is important to note that incense cones can be challenging to light and keep lit, and they generate a lot of heat. It is crucial to follow safety precautions when lighting and burning incense cones. Always ensure proper ventilation and avoid drafts or areas with high air movement, as this can affect the even burning of the incense.
