I have no specific information on the effect of KClO3 on library
materials, but I have some alternative approaches.  It is not clear
here whether you want to measure airflow or visualize the airflow.
Helium-filled bubbles are a nice approach for visualization
<URL:>, but a professional-level rig may
be a little expensive for your application.  Hot-wire anemometers
(e.g., <URL:>) are probably more
useful if you want an actual measurement although they have to be
kept clean, suffer radiant heat effects, and can have some
repeatability concerns. Regards,
