Thank you!
I may give it a try later, but have almost reached the conclusion that they are indeed only 2cm "squares" of filter paper. It was suggested that they may have
been used for TLC developing chambers (a little embarrassed that I did not think of this, but it has been a while since my last TLC). This seems like a plausible use for the squares. I'm not sure as to why they would have been cut in bulk and not as needed,
but it would have been before my time.
If anyone thinks of anything else, please let me know. I really appreciate being able to consult such a fantastic group of individuals!
Regards,
Tiffany

You can sometimes makes out faded labels by viewing them under a UV lamp.

I have an unusual questionÉmaybe.
A relatively old screw-cap amber bottle (wide mouth) was brought to my attention this morning. Inside is what appear to be rounds of filter paper that have been cut into
approximately 2cm squares. Some of the are yellowing at the edges. There was a label on the bottle, but it has long since faded. Does anyone know if these would indeed be just filter paper (vs. self-made test strips of some sort, etc) and they possibly could
have been used for? I'm at a loss as to why they would have been kept.
Sorry for a obvious lack of information, but any sugggestions/ideas would be appreciated.
