[Rockhounds] specimen labels

[J. R. Hodel]

I have been told by a trustworthy source that ink-jet ink cannot be used as it will be affected by humidity eventually, but that laser black ink is waterproof. Also that tiny 5 point labels with just a specimen number should be glued with white glue to the actual specimen, white glue being water soluble to remove the label when needed, and the specimen number on the tiny label will link the actual rock to the larger complete label with the mineral source, etc.
I personally collect rather than curate, so I gave up being organized past keeping source labels with purchased rocks and remembering where I dug my personally collected rocks. 

I know, bad me!
