I would recommend using a 4-flap enclosure made of Silversafe or
other photo-safe paper, leaving one flap slightly longer (about 1cm)
at the top edge for writing a number or information on. this will
offer your glass plates protection from abrasion etc. and when
stored upright in boxes, are easily identifiable and accessible.
