The work where was write that I wrote it's:

Z.Ceplecha, in IAU 160 (1994) pag 343-356 "Meteoroid properties
from photographic records of meteors and fireball"

Other work with (little) reference at this topic are:

but as others wrote in the past days nobody worked hard
on this matter, I think that today with photos and especially
clips we can now understand if a meteorid it's rocky,
metallic or cometary.
I can add to that near all rocky meteorites fall in rain
after esplosion in the air but near all metallic meteorites
fall single (only very big metallic meteorites fall in rain
as Cape York, Namibia, Sikhote Alin, Mexican irons,
etc.). Then when we see a bolid esplose we can near sure
that it's rocky (but this it's obvius too because 95% of
meteorites are rocky).
Can I suggest that amateurs of this list do a research on this
topic with professionals? (I cannot work on this research).
Best greetings.
