Hi All,

I whole-heartedly agree with Michael's two objections but would like
to add another problem: the four edges of the thin section glass plates.
They should always and principally be cut 45° and ground smooth to
prevent cuts.
As for rusting, this is almost self-evident but the risk of scratching
and abrading does not only occur while removing and returning the TS
to storage but also while rotating the thin section on the microscope
stage when viewing your TS in polarized light to watch minerals go to
exinction. So my vote is:

=> I collect thin sections & prefer WITH COVER SLIPS.

Best regards from
