Get rid of them. Do not use them or worry about them, or wonder about
them. Get rid of them.
1) You do not know what condition the unknown material is in, if it is
pure or possibly contaminated, subjected to detrimental storage
conditions, etc..
2) You CAN'T go on how they look, their texture, etc. You can guess what
they might be from the fact they were in a darkroom, but unless you
analyze them (have them analyzed?) you can't be absolutely sure.
3) There is no way to identify the chemicals without lots of bother and
lots of experience. Much cheaper to just buy the chemicals you need.
I would never go on anyone's assurance that the unknown is what they say
it is. Here is a short story about the problem of contaminated chemicals.
Potassium Perchlorate. No, it is not an ALT Chemical, but it is an
example of a chemical that once contaminated with foreign materials, can
explode because of the contamination.
