The duration it takes for incense to burn out depends on the type whether you use incense sticks or incense cones. Also, the specific brand. Here’s a general overview: Incense Sticks: These typically burn for a longer duration compared to cones. On average, an incense stick can last anywhere from 30 minutes to 1 hour. Some high-quality sticks may burn for even longer. Incense Cones: Cones have a shorter burn time. Most non-backflow incense cones burn for approximately 15 to 30 minutes. Backflow incense cones, designed for special backflow burners, also fall within this range. Remember that factors like the thickness of the incense, the specific blend of ingredients, and the ambient conditions (such as airflow) can influence burn times. If you’re using incense for a specific purpose (meditation, relaxation, or ambiance), consider choosing the type that aligns with your desired burn duration.
