There is a way for to known what type of material do origin at a bolid,
the light profile: with a clip but too with a unique image we can 
extrapolate
the light profile, then comparating it with light profiles in catalogs we 
can
known (near sure, but not certainly) of wich material was composed the
meteoroid that to do origin at the bolid. For to see this light profiles
it must to do a research on the old articles of some dozen years ago.
Best greetings.
