Personally, I'd not bother with trying to use this film. If (like me) you are interested in trying old films, there are plenty of safe materials available on Ebay, garage sales, etc.

You may well be OK with a small amount of film, but why risk it....it's not like it's exposed film with some important historical content which would justify special conservation. And don't overlook that there are things like your house insurance to consider...I doubt you'd be covered while knowingly using quantities of nitrate film!
