Abstract

Selon la présente invention, une première étape et une seconde étape sont répétées plusieurs fois. À la première étape, un produit chimique est vaporisé de telle sorte que la quantité de produit chimique vaporisé représente au moins deux fois une quantité de vaporisation chimique de référence qui est la quantité de produit chimique vaporisé lorsqu'une quantité prédéterminée du produit chimique est mélangée uniformément dans un matériau de base d'un encens (1). À la seconde étape, le produit chimique n'est pas vaporisé ou est vaporisé de telle sorte que la quantité de produit chimique vaporisé est inférieure à celle vaporisée à la première étape.
