Backflow incense cones are designed to guide smoke downwards through a hole in the cone, creating a waterfall effect. Unlike regular cones, backflow cones have a small hollow tunnel through the centre, ending in a hole at the bottom. The size of the hole is important, as it needs to align with the hole on the seat of the incense holder for the smoke to flow properly. The hole is created by inserting a stick into the centre of the incense dough, ensuring it doesn't go all the way through the tip of the cone. The stick is then used to remove the cone from the mould.

What You'll Learn
Backflow incense cones have a hole from top to bottom
Backflow incense cones are designed to guide smoke downwards, creating a waterfall effect. This is achieved through the presence of a small hole from the top to the bottom of the cone, which pulls the smoke downwards due to the intense heat from the ember. The hole at the bottom of the cone must align with the hole on the seat of the incense holder to ensure the smoke is not blocked and can flow through the burner's channels or slopes.
To light a backflow incense cone, the pointy end of the cone should be ignited with a match or lighter until a small flame appears. The flame should then be gently blown out, leaving a glowing ember and smoke emanating from the bottom. It may take a few seconds for the smoke to begin flowing from the bottom, and if the smoke is coming from the tip instead, the cone should be relit.
The unique downward flow of smoke in backflow incense cones is due to the shape and structure of the cone. The hollow section inside the cone, often compared to a tunnel or a pagoda, creates a low-pressure zone as the incense burns. Cooler air from outside then exerts pressure on the smoke, pushing it downward through the hole at the base of the cone. This results in a mesmerizing waterfall-like effect as the smoke flows down the backflow incense burner.
To make a backflow incense cone, it is important to leave a small amount of empty space at the top of the incense mold. A stick is then inserted into the center of the incense dough to create the bottom center hole, ensuring it does not break through the tip of the cone. This process helps to create the perfect size for the final incense cone and allows for the unique downward flow of smoke that characterizes backflow incense cones.

Smoke is pulled down through the hole into the burner
Backflow incense cones are designed with a small, hollow tunnel through the centre, ending in a hole at the bottom. When the cone is lit, the smoke is pulled down through this hole and into the burner, creating a mesmerising effect as the smoke cascades downwards. This is in contrast to conventional incense cones, which do not have a hole and therefore emit smoke from the top of the cone.
To achieve the backflow effect, it is important to ensure that the backflow cone is properly lit. This can be done by igniting the tip of the cone with a lighter or matches and allowing it to burn for a few seconds before gently blowing out the flame. If the cone has an ember, blowing gently will encourage a steady burn and help produce the desired smoke. It may take a few minutes for the backflow effect to start, as the smoke will initially rise from the top like a regular incense cone.
The unique downward flow of smoke in backflow incense is due to the design of the cone, which pulls the smoke downwards through the hole in the burner. This is caused by the intense heat from the ember, which creates a current that draws the smoke downwards. Additionally, the hole in the cone provides an outlet for the smoke, as it will not come off the hot ember due to the downward pull.
To ensure the backflow effect works correctly, it is crucial to use the correct type of cone and burner. While it is possible to modify traditional incense cones by drilling a hole in the bottom, this may not always be successful. It is recommended to use natural incense cones specifically designed for backflow burners to achieve the best results. Additionally, the burner itself should be placed in a well-ventilated room, away from drafts or breezes, as air movement can interfere with the cascading smoke effect. Regular cleaning of the burner is also important to prevent the buildup of residual oils and ash, which can impact the smoke flow.

The cone must be lit correctly to create a steady ember
To create a steady ember, the backflow incense cone must be lit correctly. The pointy end of the cone should be lit with a match or lighter, ensuring that the incense is immersed in the flame until it ignites. The flame should then be gently fanned or blown out, leaving a small glowing ember. It is important to ensure that the ember is steady and will produce continuous smoke. To do this, the flame should be allowed to burn for a few moments longer, burning about 4mm of the tip, before being gently blown out. The cone should then be glowing red, indicating a steady ember.
If the ember is glowing, the cone should be observed closely to ensure that smoke is flowing through the hole at the base. This may take a few seconds to begin. If the smoke is coming from the tip instead of the base, the cone should be re-lit. The cone must be fully ignited to create a steady ember and produce the desired smoke flow.
Handmade backflow incense cones may be more difficult to light than machine-made versions. This may be due to the density of the cones, as handmade cones are hand-squeezed and more tightly packed. To light a handmade cone, the tip should be immersed in the flame for a longer period, up to 10-15 seconds. The flame can also be left to burn out naturally, rather than being fanned.
The downward flow of smoke in backflow incense is due to the shape and structure of the cone. The hollow section in the centre creates a low-pressure zone as the incense burns, while cooler air from outside exerts pressure on the smoke. The smoke is then pushed downward by the cooler, denser air, creating a waterfall effect. This effect will only occur if the cone is lit correctly and a steady ember is created.

The hole in the cone must align with the hole in the burner
The key to the downward flow of smoke in backflow incense cones lies in the shape and structure of the cone. Unlike regular cones, backflow cones have a small hollow tunnel through the centre, often compared to a pagoda. This tunnel plays a crucial role in manipulating the airflow. As the incense burns, the heat inside the hollow space creates a low-pressure zone. At the same time, cooler air from outside exerts pressure on the smoke. Once the smoke reaches the small hole at the base of the cone, it slows down and, instead of rising, gets pushed downward by the cooler, denser air from above. The smoke then flows gracefully down the backflow incense burner, creating a mesmerising waterfall-like effect.
To achieve this effect, it is crucial that the hole at the base of the cone aligns perfectly with the designated hole or indentation on the backflow incense burner. This is because the hole in the cone pulls the smoke down due to the intense heat from the ember through the hole in the burner. Misalignment can prevent the smoke from travelling properly, disrupting the visual flow of the backflow effect. Therefore, it is important to ensure that the cone is securely seated on the burner and properly aligned with the airflow design.
To light a backflow incense cone, hold the pointy end of the cone over a flame until it ignites. Then, gently blow out the flame or its remnants. If you see a small glowing ember and smoke starts coming out of the bottom, the incense has been correctly lit. It may take a few seconds for the smoke to begin flowing from the bottom. If you notice the smoke coming from the tip instead of the base, check the ember and relight the cone if necessary to ensure the proper burn.
To make your own backflow incense cone, you will need to leave a small amount of empty space at the top of the incense mould. Then, take a stick and insert it into the centre of the incense dough to form the bottom centre hole, ensuring it doesn't go all the way through the tip of the cone. It is helpful to pre-measure the length of the hole and mark this onto the stick so that you know when to stop inserting it into the dough.

Cooler, denser air pushes the smoke down through the hole
The key to the downward flow of smoke in backflow incense cones lies in the shape and structure of the cone. Unlike regular cones, backflow cones have a small hollow section inside, often compared to a tunnel or a pagoda. This design plays a crucial role in manipulating the airflow. As the incense burns, the heat inside the hollow space creates a low-pressure zone. At the same time, cooler, denser air from outside exerts pressure on the smoke.
The smoke, now cooler, is denser than the air around it at room temperature. As a result, once the smoke reaches the small hole at the base of the cone, it slows down and gets pushed downward by the cooler, denser air from above. The smoke then flows gracefully down the backflow incense burner, creating a mesmerizing waterfall-like effect. This effect is further enhanced by the artistic design of backflow burners, which often feature steps or curves to guide the smoke's flow.
To ensure the proper flow of smoke, it is important to align the hole at the base of the cone with the designated hole or indentation on the backflow incense burner. Misalignment can prevent the smoke from travelling through the burner's channels or slopes, disrupting the visual flow of the backflow effect. Additionally, it is recommended to place the burner in an indoor environment free from wind or drafts, as even minor air movement can interrupt the downward smoke flow.
The downward flow of smoke in backflow incense cones is a result of the interplay between the shape and structure of the cone, the heat generated during combustion, and the pressure exerted by cooler, denser air from the surrounding environment. By understanding and manipulating these factors, one can create a unique and visually appealing waterfall-like effect.
