Marking glass

Has anyone got any advice on physically marking our Museum's
collection of several hundred glass positives, negatives and lantern
slides? They range in size from 2.5 inch square to  5 x 7 inch and
date to the very early 20th century. So far I have pencilled the
number and simple name on the Photosafe paper slip. But these come
adrift and there could be 50 to a box, so data is lost, making
searching for the image you want difficult. Pen and ink, or sticking
a paper number on the non-emulsion side seems a bit severe.
