Backflow incense cones are exactly as the name suggests – cone shaped incense where the incense smoke (or plume) flows in the opposite direction as “normal” incense, that is, downwards instead of upwards. This is because the incense cone has a small, hollow tunnel through the center, ending at a hole at the bottom.
This is how we think backflow incense works: incense smoke is actually more dense than normal air at room temperature because it contains tiny smoke particles. But when a normal incense is lit, smoke flows upwards because hot air is lighter than room-temperature air. In the case of a backflow incense cone, smoke enters the hollow center tunnel, where it cools as it follows the along the path. When smoke cools, it becomes denser, so when it exits the incense cone at the bottom, it flows gently downwards.
