Is inhaling incense smoke bad for you?

Incense with Heavier Smoke, Anyone???

• I have conceived of an idea for an insence burner, where the incense burns upside down inside a top & bottom-opened glass vase; the top is covered, save for a small hole. The incense is inserted into a small key ring (Like what people have on their keys), is lit, placed into the small hole, down into the vase, and is suspended by the key ring; a shot glass is placed over the key ring, to seal the vase on the top. The bottom of the vase is upheld about 2 inches from the bottom of a large bowel. When the smoke builds up in the vase, it begins to pour out from the bottom of the vase, and fills the bowel (providing the surrounding air is still). The effect is quite striking, as it looks like an ethreal fog of smoke has filled the bowl (I also have a light shining up from the bottom of the bowl); however, the smoke dissapates much too rapidly, and the effect is not a strong as it could be. Anyone know where I can find incense that produces a heavier smoke, if there is such a thing?

• Answer:

  It sounds visually lovely but the incense would burn more quickly so I hope you can find an incense that not only has heavy smoke but also burns more slowly. Perhaps instead of incense resin would work . . . Not sure if they make resin sticks. I guess I'm not being much help but I wanted to point out the obvious re. how quickly the incense will burn as a result of the inverted position.
