摘要：
Fragrance control is provided by articles of manufacture including various solid state fragrancing objects, methods of using such objects, and systems that employ one or more such objects. The solid state fragrancing object can be used to inconspicuously provide fragrance to a user in an environment by disposing the solid state fragrancing object in the environment and configuring the solid state fragrancing object as at least a portion of a fixture within the environment. The fragrancing object can be easy to manufacture, long lasting, provide fragrance that is consistently released over time, provide an indication to the user that the object needs to be replaced, and can hold a desired ratio of fragrance.
