For centuries, paper infused with incense has been produced, which can be lit on fire then immediately put out to smolder and smoke, spreading the natural resins that the paper had been infused with through the room.

These were actually preceded by Carta d'Armenia, made by the Santa Maria Novella monks since the 16th c.
